Executive Summary

The Army National Guard (ARNG) is performing Preliminary Assessments (PAs) and Site 

Inspections (SIs) for Perfluorooctanesulfonic acid (PFOS) and Perfluorooctanoic acid (PFOA) 

Impacted Sites at ARNG Facilities Nationwide. A PA for per- and polyfluoroalkyl substances 

(PFAS)-containing materials was completed for Grand Island Army Aviation Support Facility

(AASF; also referred to as the “facility”) #2 in Grand Island, Nebraska, to assess potential PFAS 

release areas and exposure pathways to receptors. The AASF #2 is constructed on a parcel of 

land that has been owned and operated by the Nebraska ARNG (NEARNG) since 2005. The 

performance of this PA included the following tasks: 

• Reviewed available administrative record documents and Environmental Data Resources,

Inc. (EDR)TM report packages to obtain information relevant to potential PFAS releases, such

as: drinking water well locations, historical aerial photographs, Sanborn maps, and

environmental compliance actions in the area surrounding the facility;

• Conducted a site visit 22 October 2019 and completed visual site inspections at locations

where PFAS-containing materials were suspected of being stored, used, or disposed;

• Interviewed a current NEARNG personnel

• Identified Area(s) of Interest (AOIs) and developed a preliminary conceptual site model (CSM)

to summarize potential source-pathway-receptor linkages of potential PFAS in soil,

groundwater, surface water, and sediment for the AOI.

Two AOIs related to potential PFAS releases were identified at the AASF #2 during the PA. The 

AOIs are shown on Figure ES-1 and described below:

Based on potential PFAS releases at the AOIs, there is potential for exposure to PFAS 

contamination in media at or near the facility. The preliminary CSM for the AASF #2, which 

presents the potential receptors and media impacted, is shown on Figure ES-2. Based on the US 

Environmental Protection Agency (USEPA) Unregulated Contaminant Monitoring Rule 3 data, it 

was indicated that no PFAS were detected in a public water system above the USEPA lifetime 

Health Advisory within 20 miles of the facility. PFAS analyses performed in 2016 had method 

detection limits that were higher than currently achievable. Thus, it is possible that low 

concentrations of PFAS were not detected during the UCMR3 but might be detected if analyzed 

today.

1. Introduction

Authority and Purpose

The Army National Guard (ARNG) G9 is the lead agency in performing Preliminary Assessments 

(PAs) and Site Inspections (SIs) for Perfluorooctanesulfonic acid (PFOS) and Perfluorooctanoic 

acid (PFOA) at Impacted Sites at ARNG Facilities Nationwide. This work is supported by the 

United States (US) Army Corps of Engineers (USACE) Baltimore District and their contractor 

AECOM Technical Services, Inc. (AECOM) under Contract Number W912DR-12-D-0014, Task 

Order W912DR17F0192, issued 11 August 2017.

The ARNG is assessing potential effects on human health related to processes at facilities that 

used per- and poly-fluoroalkyl substances (PFAS), primarily in the form of aqueous film forming 

foam (AFFF) released as part of firefighting activities, although other PFAS sources are possible. 

In addition, the ARNG is assessing businesses or operations adjacent to the ARNG facility (not 

under the control of ARNG) that could potentially be responsible for a PFAS release. 

PFAS are classified as emerging environmental contaminants that are garnering increasing 

regulatory interest due to their potential risks to human health and the environment. PFAS 

formulations contain highly diverse mixtures of compounds. Thus, the fate of PFAS compounds 

in the environment varies. The regulatory framework at both federal and state levels continues to 

evolve. The US Environmental Protection Agency (USEPA) issued Drinking Water Health 

Advisories (HA) for PFOA and PFOS in May 2016, but there are currently no promulgated national 

standards regulating PFAS in drinking water. The HA is 70 parts per trillion for PFOS and PFOA, 

individually or combined.

This report presents the findings of a PA for PFAS-containing materials at the Grand Island Army 

Aviation Support Facility (AASF; also referred to as the “facility”) #2 in Grand Island, Nebraska, 

in accordance with the Comprehensive Environmental Response, Compensation, and Liability 

Act (CERCLA), as amended, the National Oil and Hazardous Substances Pollution Contingency 

Plan (40 Code of Federal Regulations Part 300), and Army requirements and guidance. 

This PA documents the known fire training areas (FTAs) as well as additional locations where 

PFAS may have been released into the environment at the AASF #2. The term PFAS will be used 

throughout this report to encompass all PFAS chemicals being evaluated, including PFOS and 

PFOA, which are key components of AFFF.

Preliminary Assessment Methods

The performance of this PA included the following tasks: 

• Reviewed available administrative record documents and Environmental Data Resources,

Inc. (EDR)TM report packages to obtain information relevant to potential PFAS releases, such

as: drinking water well locations, historical aerial photographs, Sanborn maps, and

environmental compliance actions in the area surrounding the facility;

• Conducted a site visit 22 October 2019 and completed visual site inspections at locations

where PFAS-containing materials were suspected of being stored, used, or disposed;

• Interviewed a current NEARNG personnel

• Identified Area(s) of Interest (AOIs) and developed a preliminary conceptual site model (CSM)

to summarize potential source-pathway-receptor linkages of potential PFAS in soil,

groundwater, surface water, and sediment for the AOI.

Facility Location and Description

The AASF #2 is in Hall County, approximately 3 miles northeast of Grand Island, Nebraska. The 

AASF #2 is adjacent to the Central Nebraska Regional Airport. The AASF #2 is accessible from 

East Airport Road from the south.

The AASF #2 is constructed on a parcel of land that is approximately 49.5 acres and has been 

owned and operated by the State of Nebraska Military Department since 2005 (Appendix A). 

Before 2005, the Hall County Airport Authority owned and operated the land. In 2009, the AASF 

#2 was constructed to house the Nebraska Army National Guard maintenance support facility. In 

2014, the Grand Island Readiness Center was added to the campus. The Readiness Center is 

used to train part and fill time soldiers in aviation and skill development. Currently, no other new 

structures have been added to the AASF #2 facility.

Facility Environmental Setting

The AASF #2 is in the Platt River Lowlands of Nebraska (Figure 1-1). The Platte river flows within 

5 miles of the AASF #2. The AASF #2 is surrounded by both agricultural land, and there are three 

lakes located within 3 miles of the facility. Lake Davis, Crystal Lake and Eagles Lake are all located 

to the south of the facility. The elevation of the AASF #2 is approximately 1,860 feet above mean 

sea level.

1.5.1 Geology

The AASF #2 lies within the High Plains section of the Great Plains Province (Figure 1-2). The 

underlying geological features at the facility can be defined by four categories. The first 10 feet 

underneath the surface is alluvial silty clay and topsoil. There is also alluvial sands and gravel 

from the Grand Island Formation which have been reported to be approximately 50 to 60 feet 

thick. A thinner layer of low permeability alluvial silty clay which is about 5 to 15 feet thick from the 

Fullerton Formation is also located in the area. This clay can also be referred to as “blue clay.” 

The last layer underneath the facility is the deepest layer and can be found up to 200 feet thick. 

It is an alluvial sand and gravel from the Holdrege Formation (URS, 2006). 

Grand Island’s geology differs from the typical geological sequence of the High Plains, as there 

is no Tertiary material present (USGS, 1983). The geology the underlies the AASF #2 consist of 

material from the Niobrara Formation. This formation consists of argillaceous chalk, limestone 

and shale (USGS, 2020). There is also substantial Quaternary mantle present in this area, which 

consists of silts, clays and alluvium. There appears to be no surficial difference between the areas 

of the High Plains were there is and isn’t Tertiary materials present (USGS, 1983).

1.5.2 Hydrogeology

There are two aquifers and an aquitard located in the area of the facility; the Fullerton Formation 

Aquitard; the Holdrege Formation Aquifer; and the Formation Aquifer. The Grand Island Formation 

Aquifer is an unconfined water table aquifer within the alluvial sands and gravels of the Grand 

Island Formation. This allows for shallow groundwater under the facility. The depth to water 

ranges from 10 to 16 feet below ground surface with a total thickness of water ranging from about 

50 to 60 feet. The predominant groundwater flow in the Grand Island Formation Aquifer is to the 

northeast. The Holdrege Formation Aquifer is a confined aquifer unit within the sands and gravels 

of the Holdrege Formation. The groundwater flow of the Holdrege Formation Aquifer flows to the 

northeast, which is a similar direction as the Grand Island Formation Aquifer. The Fullerton 

Formation Aquitard is an underlying clay unit with low-permeability that acts as a barrier to 

groundwater flow. This aquitard creates a presence of head differences between the two aquifers

(URS, 2006). 

The Grand Island Formation aquifer supplies most of the water for the region in the form of 

irrigation supply and potable water. The City of Grand Island uses 21 wells that lie between two 

channels of the Platte River, using 3 pumps that allow water to be moved from the basins into 

town (City of Grand Island Utilities, 2017). 

There are no wells located within the boundary of the facility; however, there are domestic wells

and several irrigation wells downgradient and side gradient of the AASF #2. There are several 

additional livestock, irrigation, commercial/industrial wells within a 1-mile radius of the facility 

(Figure 1-2). Drinking water for the AASF #2 is supplied by the City of Grand Island, which 

sources water from groundwater via sand and gravel aquifers that underlies the area (City of 

Grand Island Utilities, 2017). Based on the USEPA Unregulated Contaminant Monitoring Rule 3 

data, it was indicated that no PFAS were detected in a public water system above the USEPA HA 

within 20 miles of the facility. PFAS analyses performed in 2016 had method detection limits that 

were higher than currently achievable. Thus, it is possible that low concentrations of PFAS were 

not detected during the UCMR3 but might be detected if analyzed today. 

1.5.3 Hydrology 

The AASF #2 is in the Platte River floodplain (Figure 1-3). The primary surface water feature 

found south of the facility and is an intermittent tributary of the Warm Slough. The Warm Slough 

generally flows southwest to northeast and eventually drains into the Platte River approximately 
PFAS Preliminary Assessment Report

Grand Island AASF #2, Grand Island, Nebraska

7

24 miles from the facility. Surface water flow direction at the site is to the southeast towards Warm 

Slough.

The Platte River is classified as the longest braided river in North America. It flows from the Rocky 

Mountains in Colorado and Wyoming to the Missouri River, which drains into the Mississippi River. 

As a braided river, the Platte River is a network of multiple small shallow channels that all flow in 

the same direction. The Platte River is prone to flooding and has contributed to flooding in Grand 

Island as recently as 2019 (URS, 2006). 

1.5.4 Climate 

The climate at the facility has four defined seasons where the summers are warm and mostly 

clear; the winters are freezing, windy, snowy and typically have a lot of cloud cover. Temperatures 

vary from average highs of 62.3 degrees Fahrenheit (°F) to average lows of 39.2 °F. The average 

annual temperature is 50.75 °F. Average precipitation is 26.61 inches of rain (World Climate, 

2019).

1.5.5 Current and Future Land Use

The AASF #2 is a controlled access facility with public roads and is adjacent to Central Nebraska 

Regional Airport. Reasonably anticipated future land use is not expected to change from the 

current land use; however, future infrastructure improvements, land acquisitions, and land use 

controls at the Central Nebraska Regional Airport are unknown.

2. Fire Training Areas

One FTA where PFAS was potentially released was identified during the PA. A description of the 

FTA is presented below and is shown on Figure 2-1. Interview records and photographs are 

included in Appendix B and Appendix C, respectively.

Non-AFFF FTA

Since 2010, personnel at the AASF #2 in conjunction with the Grand Island Fire Department, have 

conducted annual fire training drills. These drills consist of training exercises where ABC hand 

held fire extinguishers and soap/water filled TriMaxTM 30 mobile units were dispensed to the ramp 

area outside the hangar of the AASF #2 to put out small pan fires. It is reported that the TriMaxTM

30 used for fire training exercises arrived at the AASF #2 empty and has never been filled with

AFFF. The geographic coordinates are 40°57'43.84"N and 98°17'56.49"W (Figure 2-1). There 

has been no reported use of AFFF during training exercises.

3. Non-Fire Training Areas

In addition to FTAs, the PA evaluated areas where PFAS-containing materials may have been 

broadly used, stored, or disposed. This may include buildings with fire suppression systems, paint 

booths, AFFF storage areas, and areas of compliance demonstrations. Information on these 

features obtained during the PA are included in Appendices A and B. Two non-FTAs were 

identified at the AASF #2 during the PA through interviews or document review. A description of 

the non-FTA are presented below and shown on Figure 3-1. Interview records and photographs 

are included in Appendix B and Appendix C, respectively. 

Hangar Fire Suppression System

The hangar fire suppression system was installed in 2010 when the hangar was constructed. The 

geographic coordinates of the hangar are 40°57'42.38"N and 98°17'58.43"W (Figure 3-1). The 

hangar fire suppression system consists of a 250-gallon tank filled with 2 percent High Expansion 

Foam (HEF) concentrate. After installation in 2010, the fire suppression system was tested with 

a full hanger release. During the fire suppression testing, the hangar doors were closed, which 

have rubber seals at the bottom of the door to prevent leaks. The HEF was directed to the trench 

drains in the hangar, which drain to an oil/water separator and eventually discharges to the Grand 

Island City Sanitary Waste Water Treatment Plant (WWTP). The fire suppression system has 

been serviced annually by a contractor, where the system pressure is checked without releasing 

any of the HEF concentrate. The fire suppression system was last serviced in 2017 and is housed 

in a room with no floors drains adjacent to the hanger. During the visual site inspection, there was 

visible corrosion and rust stained concrete under valves in the fire suppression system room. The 

interviewee indicated this was most likely caused by the valve leaking HEF concentrate. Direct 

interviewee knowledge prior to 2017 is unavailable; therefore, it is unknown if the rubber seals at 

the bottom of the hangar doors leaked during the 2010 fire suppression system testing. 

There is a cold storage hangar located to the north of the main hangar, however it does not contain 

a fire suppression system. 

TriMaxTM 30 Fire Extinguishers

There are six TriMaxTM 30 fire extinguishers filled with AFFF located at the AASF #2. It is unknown 

when the fire extinguishers arrived at the facility. The TriMaxTM 30 fire extinguishers are placed in 

various locations on the ramp area in front of the two hangars. One TriMaxTM 30 extinguisher is

filled with soap and water for training purposes. There were two additional empty TriMaxTM 30

extinguishers found in crates in the cold storage hanger at the facility that were never filled with 

AFFF. The fire extinguishers were serviced in 2019; the NEARNG sent the AFFF-filled TriMaxTM

30 fire extinguishers to the Lincoln AASF #2 in Lincoln, NE where they could be sent to a 

contractor to undergo hydrostatic testing. There have been no reports or accounts of the TriMaxTM

30 extinguishers ever being used or dispensed at the facility.

5. Adjacent Sources

One potential off-facility source of PFAS adjacent to the AASF #2, not under the control of the 

ARNG, was identified during the PA. Based on interviews with NEARNG personnel (Appendix 

B) and historical document review, the identified adjacent area with potential AFFF releases is

outside the AASF #2 boundaries. A description of the adjacent source is presented below, and

the adjacent source is shown on Figure 5-1.

Central Nebraska Regional Airport

The Central Nebraska Regional Airport geographic coordinates are 40°58'9.22"N; 98°19'7.22"W. 

The Central Nebraska Regional Airport was constructed in 1937 and is owned and operated by 

the Hall County Airport Authority. The facility is northwest and side gradient of the Central 

Nebraska Regional Airport. The airport does not have a fire department. There are public, 

corporate, and private aircraft hangars, which could potentially have AFFF fire suppression 

systems.

6. Preliminary Conceptual Site Model

Based on the PA findings, two AOIs were identified at the AASF #2: AOI 1 Hangar Fire 

Suppression System and AOI 2 TriMaxTM 30 Fire Extinguishers Location. The AOI locations are

shown on Figure 6-1. The following sections describe the CSM components and the specific CSM 

developed for AOI 1 and AOI 2. The CSM identifies the three components necessary for a 

potentially complete exposure pathway: (1) source, (2) pathway, (3) receptor. If any of these 

elements are missing, the pathway is considered incomplete. 

Pathways

In general, the potential PFAS exposure pathways are ingestion and inhalation. Human exposure 

via the dermal contact pathway may occur, and current risk practice suggests it is an insignificant 

pathway compared to ingestion; however, exposure data for dermal pathways is sparse and 

continues to be the subject of PFAS toxicological study (National Ground Water Association, 

2018). 

Potential AFFF releases identified at the AASF #2 may have occurred on paved surfaces and 

surface soil. AFFF releases to the paved surfaces could have infiltrated the subsurface via cracks 

in the pavement or joints between areas that are paved with different materials. In addition, 

potential AFFF releases may have occurred on surface soil; which could have infiltrated 

subsurface soil. Ground-disturbing activities may result in potential exposure to surface soil, 

subsurface soil, and groundwater. The preliminary CSM for AOI 1 and AOI 2 are shown on Figure 

6-2, and Figure 6-3, respectively.

PFAS are water soluble and can migrate readily from soil to groundwater via leaching. There are 

several monitoring, commercial/industrial, irrigation, livestock, and domestic wells that exist within 

a 4-mile radius. Additionally, it is possible that unregistered private drinking water wells and 

domestic exist with 4 miles downgradient of the facility and may result in potential exposure via 

ingestion of groundwater.

Receptors

Receptors include construction workers and off-facility residents. These receptors as they pertain 

to the facility are described below:

• Site workers typically work at or use the site and may come into contact with the surface soils.

• Construction workers are considered workers who represent a utility worker or other worker

who would be exposed to subsurface conditions and groundwater through ground-disturbing

activities.

• Off-facility residents identify receptors who occupy properties outside of the AASF #2. Offfacility residents may come into contact with groundwater using unregistered, private,

domestic wells.

The preliminary CSM for the AASF #2 indicates which specific receptors could potentially be 

exposed to PFAS. The preliminary CSMs for AOI 1 and AOI 2 are shown on Figure 6-2, and 

Figure 6-3, respectively.

AOI 1 Hangar Fire Suppression System 

The hangar fire suppression system consists of a 250-gallon tank filled with 2 percent HEF 

concentrate. After installation in 2010, the fire suppression system was tested with a full hanger

release. During the fire suppression testing, the hangar doors were closed, which have rubber 

seals at the bottom of the door to prevent leaks. The HEF was directed to the trench drains in the 

hangar, which drain to an oil/water separator and eventually discharges to the Grand Island City 

Sanitary Waste Water Treatment Plant (WWTP). Direct interviewee knowledge prior to 2017 is 

unavailable; therefore, it is unknown if the rubber seals at the bottom of the hangar doors leaked 

during the 2010 fire suppression system testing. Potential PFAS exposure pathways resulting 

from potential releases at AOI 1 are described in Table 6-1. 

Table 6-1 Exposure Pathways at AOI 1

Pathway Receptor

Subsurface Soil Considered a potentially complete pathway to construction workers via 

ingestion or inhalation of dust

Groundwater Considered a potentially complete pathway to construction workers and 

residents via ingestion

AOI 2 TriMaxTM 30 Fire Extinguishers Location

There are six TriMaxTM 30 fire extinguishers filled with AFFF located at the AASF #2. It is unknown 

when the fire extinguishers arrived at the facility. The TriMaxTM 30 fire extinguishers are placed in 

various locations on the ramp area in front of the two hangars. There have been no reports or 

accounts of the TriMaxTM 30 extinguishers ever being used or dispensed at the facility; however, 

it is possible that leaks or spills may have occurred on the ramp area since direct interviewee 

knowledge from 2010 to 2017 is unavailable. Any potential releases to the paved surfaces could 

have migrated a short distance onto the surrounding surface soil. Potential PFAS exposure 

pathways resulting from potential releases at AOI 2 are described in Table 6-2. 

Table 6-2 Exposure Pathways at AOI 1

Pathway Receptor

Surface Soil Considered a potentially complete pathway to site workers, and 

construction workers via ingestion or inhalation of dust

Subsurface Soil Considered a potentially complete pathway to construction workers via 

ingestion or inhalation of dust

7. Conclusions

This report presents a summary of available information gathered during the PA on the use and 

storage of AFFF and other PFAS-related activities at the AASF #2. The PA findings are based on 

the information presented in Appendix A and Appendix B. 

Findings

Two AOIs related to a potential PFAS release were identified (Table 7-1) at the AASF #2 during 

the PA (Figure 7-1).

Based on potential PFAS releases at the AOIs, there is potential for exposure to PFAS 

contamination in media at or near the facility. The preliminary CSMs for AOI 1 and AOI 2, which 

presents the potential receptors and media impacted, are shown on Figure 6-2 and Figure 6-3. 

The following areas discussed in Section 2 through Section 5 were determined to have no 

suspected PFAS releases (Table 7-2).

Rationale for No Suspected Release 

Determination

Non-AFFF FTA NEARNG

ABC fire extinguishers and TriMaxTM 30 

extinguishers filled with soap/water were used

during training exercises.

Cold Storage Hangar NEARNG

Two empty TriMaxTM 30 fire extinguishers were 

found on crates in the cold storage hangar. The 

TriMaxTM 30 units have never been filled with 

AFFF. 

Uncertainties

A number of information sources were investigated during this PA to determine the potential for 

PFAS-containing materials to have been present, used, or released at the facility. Historically, 

documentation of PFAS use was not required because PFAS were considered benign. Therefore, 

records were not typically kept by the facility or available during the PA on the use of PFAS in 

training, firefighting, or other non-traditional activities, or on its disposition. 

The conclusions of this PA are based on all available information, including: previous 

environmental reports, EDRsTM, observations made during the VSI, and interviews. Interviews of 

personnel with direct knowledge of a facility generally provided the most useful insights regarding 
PFAS Preliminary Assessment Report

Grand Island AASF #2, Grand Island, Nebraska

24

a facility's historical and current PFAS-containing materials. Sometimes the provided information 

was vague or conflicted with other sources. Gathered information has a degree of uncertainty due 

to the absence of written documentation, the limited number of personnel with direct knowledge 

due to staffing changes, the time passed since PFAS was first used (1969 to present), and a 

reliance on personal recollection. Inaccuracies may arise in potential PFAS release locations, 

dates of release, volume of releases, and the concentration of AFFF used. There is also a 

possibility the PA has missed a source of PFAS, as the science of how PFAS may enter the 

environment continually evolves.

In order to minimize the level of uncertainty, readily available data regarding the use and storage 

of PFAS were reviewed, retired and current personnel were interviewed, multiple persons were 

interviewed for the same potential source area, and potential source areas were visually 

inspected. Table 7-3 summarizes the uncertainties associated with the PA. 

Table 7-3: Uncertainties

Area of Interest Source of Uncertainty

AASF #2 Direct interviewee knowledge is not available before 2017. 

Whether potential use, storage, or release of PFAS-containing 

materials occurred at this facility from 2010 to 2017 is 

unknown. 

AASF #2 It is unknown whether the 2 percent C2 HEF contains 

fluorinated compounds. 

AASF #2 It is unknown when the TriMaxTM 30 fire extinguishers arrived 

at the facility. There have been no reports or accounts of the 

extinguishers ever being used or dispensed at the facility; 

however, direct interviewee knowledge from 2010 to 2017 is 

unavailable.

Potential Future Actions

Interviews and records (covering 2017 to present) indicate that activities may have resulted in 

potential PFAS releases at the AOI identified during the PA, however the environmental media at 

the AASF #2 was not directly impacted. Table 7-4 summarizes the rationale used to determine if 

the AOI should be considered for further investigation under the CERCLA process and undergo 

an SI.

ARNG will evaluate the need for an SI at the AASF #2 based on the potential receptors, the

potential migration of PFAS contamination off the facility, and the availability of resources.

2.1 EVALUATION OF DISCHARGE POTENTIAL

The facility is located northeast of Grand Island, Nebraska adjacent to the Central Nebraska 

Regional Airport. The facility is approximately 4,000 feet northwest of an intermittent tributary of 

Warm Slough. Warm Slough generally flows from southwest to northeast (refer to Figure 1, 

Topographic Map, Appendix A) and eventually drains into the Platte River approximately 24 miles 

from the facility. Surface water flow direction at the site is to the southeast towards Warm Slough. 

Detailed descriptions of drainage pathways related to releases are provided in Section 3.7. Based 

on the volume of oil stored and spill prevention and containment measures at this facility, it is 

unlikely for a release to reach navigable waters.

2.2 DISCHARGE HISTORY

There have been no releases from containers subject to SPCC regulations at this facility.

Olsson Project No. 016-2929 7

PART 3: DISCHARGE PREVENTION - GENERAL SPCC PROVISIONS

3.1 FACILITY DESCRIPTION (40 CFR 112.7(A)(3))

The NEARNG AASF 2 facility consists of the Administration and Maintenance Hangar, Controlled 

Waste Building, Storage Buildings, Readiness Center, and parking lots. Oil storage in containers 

greater than 55-gallons includes JP8 jet fuel, used oil, used hydraulic fluid, used fuel, and diesel 

fuel. Oil is stored in mobile fuel tankers (MFTs), 55-gallon drums, a double-walled generator tank, 

and a 10,000-gallon double-walled aboveground storage tank (AST). A 1,222-gallon capacity 

underground oil-water separator (OWS) is also located at the facility. The capacity is below the 

42,000-gallon threshold for SPCC requirements.

3.2 OIL STORAGE (40 CFR 112.7(A)(3)(I))

Oil containers at this facility that fall under the SPCC regulations are listed in Table 3.1. The 

location of oil storage is depicted on Figure 3, Appendix A.

An electric transformer is located on the west side of the Administration and Maintenance Hangar. 

The transformer is not included in this plan because the City of Grand Island Utilities is the owner 

and is responsible for spill prevention of this device.

The facility had a 15,000-gallon AST that never contained fuel. It has been removed from the site. 

The facility may store 600-gallon fuel pods, but these pods are always stored empty.

Olsson Project No. 016-2929 8

3.3 DISCHARGE PREVENTION MEASURES (40 CFR 112.7(A)(3)(II))

AASF 2 has developed procedures for the routine handling of oil including loading, unloading and 

transfer of oil stored at the facility. A description of these procedures is provided in Section 3.7.

3.4 DISCHARGE OR DRAINAGE CONTROLS (40 CFR 112.7(A)(3)(III))

AASF 2 has discharge and drainage controls in place to prevent a release of oil or oil-contaminated 

water from reaching navigable waters. These include secondary containment (see Sections 3.6 and 

3.7) and water discharge procedures (see Section 4.1). 

3.5 DISCHARGE RESPONSE AND SPILL REPORTING (40 CFR 112.7(A)(3)(IV, V, VI), (4))

Discharge response and spill reporting will be conducted in accordance with the Spill Notification 

and Response Procedures in Appendix B. A spill accident report form (Appendix B) will be 

completed upon detection of any release of oil. Additional information on spill response is provided 

in the Army National Guard Oil Spill Prevention and Contingency Plan, Section 1 (Appendix C).

The following regulatory agencies may need to be contacted in the event of a release. Regulatory 

agency reporting will be conducted by CFMO-ENV.

3.5.1 NRC Notification Procedure 

Any release of oil that reaches waters of the United States (this includes a discharge to a 

sanitary or storm sewer) must be immediately verbally reported to the National Response Center 

(NRC) at 1-800-424-8802. The following information must be provided to the NRC:

1. The exact address or location and phone number of the facility;

2. Date and time of discharge;

3. Type of material discharged;

4. Estimate of the total quantity discharged to navigable waters;

5. Source of the discharge;

6. Description of all affected media;

7. Cause of the discharge;

8. Any damages or injuries caused by the discharge;

2 – Based on fuel remaining in MFT when it is out of use.

3.7 SPILL PREVENTION MEASURES (40 CFR 112.7(C))

The following subsections discuss the control measures in place to prevent and contain releases. 

Overfill prevention measures are discussed in Section 4.2.8.

3.7.1 MFTs

When not fueling, the MFTs are parked in secondary containment (MFT containment pad, See 

Figure 3) that is designed to contain 110% of the volume of the largest compartment (see 

Containment Calculations, Appendix D).

The MFTs will receive fuel from a transport truck or off-site source and deliver fuel to aircraft on 

the facility apron. When receiving or delivering fuel, the most likely spill is a hose rupture that 

will take approximately 30 seconds to stop. Based on fuel transfer rate of approximately 100

gallons per minute, a maximum of 50 gallons of fuel may be released. A spill kit located on the 

MFT could be used to control a spill of this magnitude.

Additional spill prevention measures associated with MFT fueling are discussed in the Army 

National Guard Oil Spill Prevention and Contingency Plan, Section 3 (Appendix C). 

3.7.2 55-gallon Drums

The 55-gallon drums are stored in the Controlled Waste Building. The controlled waste building 

has raised side walls and a sloped floor that leads to a sump. The building walls, floor, and 

sump serve as containment for any release from the drums (see Containment Calculations, 

Appendix D). Spills that may occur during filling of the drums from other small containers would 

be contained in the building. When the drums are full, a licensed hauler evacuates the drum by 

vacuum removal of the contents. If a hose located outside of the building were to break during 

oil removal, the spill volume would be minimal and would be controlled by a spill kit. 

3.7.3 Generator

The facility generator has an integral, on-board 1,080-gallon diesel tank which is double walled

providing secondary containment. Any spills that may occur during fuel delivery would be 

controlled by the facility spill kit.

3.7.4 Out of Use MFTs

The facility is used to store four MFTs that are not in use. The MFTs are stored empty except 

for approximately 100 gallons remaining in the tank to prevent seals from drying out. A release 
NEARNG AASF 2 Spill Prevention Control and Countermeasure Plan

 Grand Island, Nebraska

Olsson Project No. 016-2929 12

from the out of use MFTs would drain from the paved parking area west to a drainage ditch. 

The drainage ditch does not have an outlet and thus serves as secondary containment.

To assure the out of use MFTs do not contain more than 100 gallons, access to the fill piping is 

secured by locks and a sign is placed on the MFT indicating it is out of use.

3.7.5 10,000-gallon AST

A 10,000-gallon double-walled AST is located north of the MFT parking area. A truck offloading 

pad and pump station are located to the south of the AST. Bollards surround the pump pad and 

piping extending from the tank to the pump pad. The truck offloading pad slopes to a drain and a 

containment basin to capture any leaks from the delivery truck. The pump station is contained 

on a pad with a 6-inch high curb to capture minor leaks from the pump and piping. A curbed 

concrete gutter runs beneath the piping from the AST pad to the pump station. The piping which 

runs vertically down the tank, plus one foot of horizontal piping from the tank to the edge of the 

tank pad (for the loading and offloading line), is not contained within secondary containment.

The total amount of fuel contained within the piping that does not have secondary containment is 

approximately 7.5 gallons. The piping would contain fuel during loading and offloading. The 

AST will be recirculated regularly. Trained personnel will be present during AST recirculation. 

The pump is not operational when loading, offloading, or recirculation is not occurring. A tank 

gauge with overfill alarm and an overfill prevention valve are installed to prevent overfilling the 

tank during filling of the tank. Trained personnel are present during the entire delivery of fuel. 

Any spills that may occur during fuel delivery or tank recirculation would be controlled by the 

facility spill kit located in the Controlled Waste Building. The piping and tank is inspected 

monthly for leaks.

3.8 PRACTICABILITY OF SECONDARY CONTAINMENT (40 CFR 112.7 (D))

Implementing secondary containment is practicable and feasible for the site; therefore, this section 

does not apply. 

3.9 INSPECTIONS, TESTS AND RECORDS (40 CFR 112.7(E), (K), AND 112.8(C)(6))

NEARNG personnel conduct inspections for the bulk storage containers in accordance with the 

guidance provided in the Steel Tank Institute (STI) - Standard for the Inspection of Above Ground 

Storage Tanks, SP001, September 2011, which is an EPA accepted industry standard. Personnel 

conducting these inspections will meet the following qualifications: 

• Knowledgeable of the facility operations and;

• Knowledgeable regarding the type of container, its associated components and the 

characteristics of the liquid stored. 

Based on SP001, the MFTs and the 55-gallon drums are classified as Category 1 portable 

containers, which do not require integrity testing, only periodic inspections. The generator tank is 

Category 1 and requires monthly and annual inspections. Due to generator size and containment 

equipment, no integrity testing of this container is required.
NEARNG AASF 2 Spill Prevention Control and Countermeasure Plan

 Grand Island, Nebraska

Olsson Project No. 016-2929 13

All inspections will be completed using the appropriate inspection forms in Appendix E. Inspections 

are also conducted any time material repairs to the containers are made. All inspection forms are 

maintained in the plan for a period of three years. The inspection schedule is summarized on Table 

3.6 below.

3.10 PERSONNEL, TRAINING, AND DISCHARGE PREVENTION PROCEDURES (40 CFR 

112.7(F))

NEARNG provides spill prevention training and review to all employees responsible for oil 

management and implementing this plan. The training and review includes the operation and 

maintenance of equipment to prevent discharges; monitoring systems; discharge procedure 

protocols; regulations concerning reporting spills; general facility operations; updating names and 

phone numbers in the SPCC Plan; and the overall contents of this SPCC Plan. Refresher training is 

provided for these employees once per year and new employees are trained within 30 days of 

employment. A list of employees who have received this training is maintained by NEARNG. During 

each training session, any discharges or failures, malfunctioning components, and any recently 

developed precautionary measures will be discussed. A typical record training form is provided in 

Appendix F.

3.11 SECURITY (40 CFR 112.7(G))

The following security measures are in-place at the facility:

• Unauthorized access to the facility is controlled by a fence encompassing the entire property 

perimeter as well as a security guard. This overall site security is also adequate for all pump 

controls and drain valves, 
NEARNG AASF 2 Spill Prevention Control and Countermeasure Plan

 Grand Island, Nebraska

Olsson Project No. 016-2929 14

• Transfer lines and fill ports (as applicable) are capped for out of use tanks/containers;

• The Controlled Waste Building, where 55-gallon drums are stored, is locked when the facility 

is unattended;

• Facility lighting is provided near the MFT parking, inside the controlled waste building, and 

near the generator. Lighting is sufficient to detect a discharge and to deter vandals.

3.12 TANK TRUCK LOADING/UNLOADING ASSOCIATED WITH LOADING RACKS (40 

CFR 112.7(H))

The facility does not have a loading rack; therefore, this section is not applicable. 

3.13 BRITTLE FRACTURE EVALUATION (40 CFR 112.7(I))

This section is not applicable as the facility does not have field-constructed ASTs. 

3.14 CONFORMANCE WITH STATE AND LOCAL APPLICABLE REQUIREMENTS (40 CFR 

112.7(J))

The Nebraska State Fire Marshal’s office regulates storage of class 1 liquids per NFPA 30 and 

NFPA 407. All oil storage containers at the facility conform to these standards. The State of 

Nebraska has not promulgated an SPCC rule that is more stringent than the federal 40 CFR 112 

requirements. Therefore, this SPCC Plan is written to conform with 40 CFR part 112 requirements. 

All discharge notifications are made in compliance with local, state, and federal requirements.

3.15 QUALIFIED OIL-FILLED OPERATIONAL EQUIPMENT (40 CFR 112.7(K))

As was previously mentioned, the oil-filled transformers located on-site are the property of the power 

company, who is responsible for providing spill prevention measures for the transformers.

PART 4: SITE SPECIFIC REQUIREMENTS

4.1 FACILITY DRAINAGE (40 CFR 112.8(B) AND (C)(3))

The MFT secondary containments can be drained by opening the valve on the containments. The 

valves are kept closed and can only be opened by authorized personnel.

In the event that water from rainfall or snowmelt accumulates within the secondary containment, it 

will be visually inspected for the presence of oil. An “SPCC Secondary Containment Drainage 

Report” form, provided in Appendix G, will be filled out. If no oil or sheen is noted, the water will be 

discharged to the ground surface. If there is evidence of oil in the containment area, it will be 

soaked up or pumped into portable storage tanks or drums. Records of all water discharges and/or 

oil collection are maintained as described in Section 4.5. Additional information on drainage of 

secondary containment devices is discussed in the Army National Guard Oil Spill Prevention and 

Contingency Plan, Section 3 (Appendix C).

Oil transfer activities may occur outside containment in undiked areas. Controls of potential spills 

from these activities are discussed in Section 3.7.

The facility has an underground OWS designed to capture oil in facility discharge. The effluent from 

the OWS discharges to the sanitary sewer. The OWS is inspected annually and pumped every 

1-2 years. 

4.2 BULK STORAGE CONTAINERS (40 CFR 112.8(C))

The following discussion demonstrates compliance with the requirements concerning the oil storage 

containers used at the facility. 

4.2.1 Construction (40 CFR 112.8 (c)(1))

All containers are constructed of steel, polyethylene, or fiberglass, which are all compatible with 

the oil stored. The oil is stored under standard atmospheric conditions and the containers are 

vented as appropriate to prevent accumulation of pressure. 

4.2.2 Secondary Containment (40 CFR 112.8 (c)(2))

All of the secondary containment devices are capable of containing the appropriate capacity of 

the container (see Appendix D). The secondary containment structures are made of materials 

compatible with oil and are sufficiently impermeable so that a discharge of oil will be observed. 

4.2.3 Drainage of Secondary Containment (40 CFR 112.8 (c)(3))

Refer to Section 4.1.

4.2.4 Corrosion Protection for Buried Metallic Tanks (40 CFR 112.8 (c)(4))

The facility does not operate any underground storage tanks; therefore, this section is not 

applicable. 
NEARNG AASF 2 Spill Prevention Control and Countermeasure Plan

 Grand Island, Nebraska

Olsson Project No. 016-2929 16

4.2.5 Partially Buried and Bunkered Storage Tanks (40 CFR 112.8 (c)(5))

The facility does not operate any partially buried or bunkered storage tanks; therefore, this 

section is not applicable. 

4.2.6 Inspections and Testing (40 CFR 112.8 (c)(6))

Inspections of containers are conducted by facility personnel in accordance with industry 

guidelines and site-specific conditions (refer to Section 3.8). Additional inspections and testing 

requirements are discussed in the Army National Guard Oil Spill Prevention and Contingency 

Plan (Appendix C).

4.2.7 Heating Coils (40 CFR 112.8 (c)(7))

The facility does not operate any containers using heating coils; therefore, this section is not 

applicable. 

4.2.8 Overfill Prevention Systems (40 CFR 112.8 (c)(8))

To prevent overfilling, the MFTs have site gauges, high level shut-offs, and procedures which 

only allow filling within 50 gallons of capacity. 

The 10,000-gallon AST has an overfill prevention valve, installed at the fill port of an 

aboveground storage tank. The valve terminates flow of product when the liquid level reaches a 

preset warning level.

When fueling aircraft, overfills are prevented by the aircraft’s automatic float shut-off and 

procedures requiring personnel to be present during all fueling operations.

The used oil, used hydraulic fluid, and used fuel drums are filled in small increments using small 

containers. The fluid level in the drums can be observed during the filling operations to prevent 

overfill.

The generator will be filled using a delivery truck equipped with an automatic shut-off nozzle. 

Additionally, AASF 2 personnel will be present during all fuel transfers.

Additional overfill prevention measures are discussed in the Army National Guard Oil Spill 

Prevention and Contingency Plan, Section 3 (Appendix C).

4.2.9 Effluent Treatment Facilities (40 CFR 112.8 (c)(9))

An OWS with a 1,222-gallon capacity and a pit is located underground to the west of the hangar.

All wastewater lines from AASF #2 lead to the OWS. The OWS is inspected annually and 

contained oil is pumped out every 1-2 years as needed. If repairs are needed, the OWS will be 

emptied and repairs will be completed prior to returning the OWS to use. Water from the OWS 

discharges to the sanitary sewer system.

4.2.10 Visible Discharges (40 CFR 112.8 (c)(10))

Visible discharges from tanks, containers, piping, and other appurtenances will be mitigated 

immediately. If the discharge cannot be repaired, the container will be emptied. 
NEARNG AASF 2 Spill Prevention Control and Countermeasure Plan

 Grand Island, Nebraska

Olsson Project No. 016-2929 17

4.2.11 Mobile or Portable Storage Containers (40 CFR 112.8 (c)(11))

Mobile and portable storage container spill prevention measures are discussed in Section 3.7.

4.3 TRANSFER OPERATIONS, PUMPING, AND FACILITY PROCESSES (40 CFR 

112.8(D))

The facility does not have buried or above ground piping. Facility inspections include all 

components of the oil storage containers as discussed in section 3.8. Because there is no piping,

signs warning vehicles are not necessary.

4.4 SUBSTANTIAL HARM CRITERIA (40 CFR 112.20(E))

The facility does not meet the Substantial Harm Criteria based on its potential oil storage and other 

criteria. The approximate maximum volume of the oil storage on site is 27,130 gallons. A 

completed Certification of the Applicability of the Substantial Harm Criteria Checklist for the facility is 

included in Appendix H.

4.5 RECORD KEEPING

The inspection, testing, and training records will be maintained in the SPCC Plan for at least three 

years. Completed forms will be kept in Appendix I of this Plan.

4. REQUIREMENTS FOR SPILL NOTIFICATION AND RESPONSE PROCEDURES

a. The Department of the Army (DA) requires that all installations with the capability to 

release oil and/or hazardous substances in quantities which may be harmful to the environment 

but that do not exceed the 1,320 gallon Spill Prevention, Control and Countermeasures Plan 

(SPCCP) requirements, maintain written procedures on spill notification to include reporting and 

response at potential spill sites or at the office responsible for the facility. Spill contingency 

planning will be commensurate with the operation, quantity, toxicity, and potential for 

environmental damage from the materials used or stored at a particular site. 

5. PURPOSE:

The purpose of these procedures is to establish spill notification and response procedures 

and resources to be used to contain, report, and cleanup any oil and hazardous substance spills 

which may occur at any NEARNG facility. 

NOTE: These procedures are for immediate response to an oil and/or hazardous 

substance situation. 

6. DUTIES OF FOSC (Facility On-Scene Coordinator):

The FOSC is responsible for coordinating the activities of the Facility Response Team 

(FRT) relative to containment and cleanup of oil and hazardous substance spills. At least one 

alternate FOSC will be designated. 

7. DUTIES OF FRT (Facility Response Team):

The FRT is the spill response team performing functions and duties as assigned and/or 

directed by the FOSC. The FRT will follow the SPILL RESPONSE PROCEDURES outlined in 

#3.

 

8. MATERIAL RESOURCES:

Each facility is required to have a spill kit and keep sufficient volume, as judged by the 

FOSC, on hand to contain and cleanup the normal amount of oil or hazardous substances stored 

and used at that facility.

OIL SPILL PREVENTION AND CONTINGENCY PLAN

INTRODUCTION

Mobile Fuel Tankers (MFTs) are used by the Army National Guard (ARNG) for a

variety of transportation-related purposes. Based on ARNG history, the most

common uses with the potential to adversely affect the environment include

fuel transport, refueling operations, fuel transfer, and parking. This plan is

designated to address these typical potential spill situations and discuss spill

prevention and response contingencies.

ABOUT THIS PLAN

Purpose and Scope

The purpose of this Oil Spill Prevention and Contingency Plan (OSPCP) is to

establish procedures for preventing and responding to discharges that may

occur from ARNG-owned MFTs. Designed using guidance from the Clean

Water Act (CWA), and intended to meet the requirements for a Department of

Transportation (DOT) Response Plan for MFTs (49 CFR 130.31), this OSPCP

also provides guidance for transporting fuel, conducting refueling operations,

transferring fuel, and parking.

Filing This Plan

This OSPCP must be kept in each MFT, as well as one copy must be kept on

file at the ARNG’s State Environmental Office where the MFT is assigned.

By law this plan only applies to MFTs with a capacity of 3,500 gallons or more

(49 CFR 130.31), but may be kept in MFTs with less than a 3,500-gallon

capacity as a guidance document for preventing and responding to spills. As

a Best Management Practice (BMP) all ARNG MFTs are required to have this

OSPCP in them at all times. In order to provide maximum protection to the

environment and the general public, the ARNG is instituting the plan to

exceed the regulatory standards and provide spill plans to all of its MFTs.
v

Army National Guard

OIL SPILL PREVENTION AND CONTINGENCY PLAN

Spill response supplies will also be carried in all ARNG MFTs at all times.

MANAGEMENT RESPONSIBILITY

Unit Commanders are directly responsible for oil spill prevention and control

for this MFT. The United States ARNG is committed to providing the

necessary resources to prevent spills and, if necessary, to quickly control and

remove harmful quantities of oil or hazardous substances discharged from

this vehicle.

PRIVATE RESPONSE PERSONNEL

In accordance with (IAW) 49 CFR 130.31(3), a list of private personnel and

equipment available to respond to a spill from this vehicle is provided in the

plastic folder at the back of this OSPCP. This list may also contain public

services that respond to spills, such as the Fire Department. This list must

be maintained by the individual states where this plan is employed.

STATE-SPECIFIC REQUIREMENTS

Your state may have adopted regulations or policies that are more stringent

than the requirements of this plan. A summary of those requirements, if

any, can be found in the plastic folder at the back of this OSPCP. In the event

you are hauling fuel in another state and need guidance, refer to the list of

all state Departments of Transportation (DOT) and Emergency Response

coordinators in Appendix A. This list has the state DOT and emergency

contact phone numbers. There is also a list of ARNG Environmental Office

phone numbers provided in Appendix B.

SPILL RESPONSE AND CONTINGENCY

A timely response to a spill is critical. How you respond depends

on whether the spill is an on whether the spill is an emergency or an incidental incidental release. release

Responding to Responding to Emergency Emergency Releases Releases

Emergency spills are spills that CANNOT be absorbed or otherwise controlled

at the time of release by personnel in the immediate release area. These

include spills that pose a significant safety or health hazard, such as fire or

explosion, or that may reach a water source.

Follow these steps when responding to an emergency spill:

Step 1. Evacuate all personnel to a safe distance upwind from the spill.

Secure the area, and immediately notify the local Fire Department.

If phone number is unavailable, use the phone numbers provided

in the plastic folder at the back of this OSPCP or the Appendices.

Be prepared to provide the following information:

! Your name

! Location of spill

! Substance spilled

! Number of any injured personnel and nature of injuries

! Amount spilled and extent it has traveled

! Amount stored and rate at which substance is spilling

(estimated)

! Time spill started

When the Fire Department/Emergency Spill Response arrives, make yourself

available to the Senior Emergency Response Official in charge.

Step 2. As soon as possible, notify by telephone the state ARNG

Environmental Section (Appendix A) or the Staff Duty Officer, and

the Unit Commander. A list of important phone numbers is provided

in the plastic folder at the back of this OSPCP, and/or in the

Appendices. Only notify other agencies and/or response

organizations if instructed to do so by your chain of command.

Step 3. Complete the Spill Incident Report form located in the plastic folder

at the back of this OSPCP and submit it to your state ARNG

Environmental Section within 72 hours. An example of the form is

provided at the end of this section for you to photocopy and use if no

printed copies are available.

Responding to Responding to Incidental Incidental Releases Releases

Incidental releases are spills small enough to be handled using personnel

and equipment routinely located in the immediate area of the release. These

include, but are not limited to, fuel spills of less than 25 gallons that do not

pose a significant safety or health hazard such as a fire or an explosion, or

that do not pose a risk to a water source.

Follow these steps when responding to an incidental release:

Step 1. If necessary, evacuate all personnel to a safe distance upwind

from the spill and secure the area.

Step 2. Remove the source. Turn off all sources of ignition. While

wearing the proper personal protective equipment (PPE), and

without placing yourself at risk of injury, attempt to stop the

source by closing valves or shutting off pumps.

Step 3. Using the spill kit maintained on the MFT, envelop the spill.

Stop or slow the spread of the spill by diking or by diverting

the flow to a natural pit for temporary containment and clean

up.

Step 4. Absorb and/or accumulate the spill using a dry sweep,

absorbent socks, absorbent pads, soil, etc. Do not use metal not 

shovels or rakes or any other equipment that may cause a

spark.

Step 5. Place all spill residue and related waste in containers. Scoop

or shovel contaminated media (soil, gravel, etc.) into a DOTapproved container, separating liquids from solids. Make

sure you label and mark the container to identify its

contents.

Step 6. As soon as possible, notify by telephone the state ARNG

Environmental Section or the Staff Duty Officer, and the Unit

SPILL PREVENTION IN REFUELING & FUEL TRANSFER

OPERATIONS

MFT operators must comply with state, local, and installation (training area)

regulations when performing refueling and all other types of fuel transfer

operations. Other types of fuel transfer operations may include loading of

bulk fuel to or from an aboveground storage tank (AST). This section,

developed IAW 49 CFR 130 and 177, provides guidelines for selecting and

setting up a refueling site, conducting refueling and other fuel transfer

operations, and closing a refueling site.

Selecting a Refueling Site

When selecting a refueling site, the driver must consider SAFETY and the

ENVIRONMENT. Important criteria in selecting a refueling site include the

location, surface characteristics and elevation, and natural obstacles and

accessibility at the site.

Location

The driver should look for a site AWAY from environmentally sensitive areas,

and ensure that the refueling location is NOT near any of the following: NOT

! Ditches, streams, lakes, and other bodies of water

! Drainage Swales

! Drinking water or other water supply wells

Surface Characteristics and Elevation

When possible, select a refueling site where the fuel truck can be

parked on a FLAT, IMPERVIOUS surface, such as concrete or

asphalt pavement. If such a surface is not available, choose a site

where the terrain will direct a spill into a natural pit for temporary

containment and allow for easier clean-up.

Natural Obstacles and Accessibility

Select a refueling site that is readily accessible for the vehicles and

equipment being refueled. Make sure that it’s clear of debris such as

equipment, shrubs, rocks, and tree limbs. Make sure the site is large enough

to handle the expected volume of traffic, and that it includes a waiting area

for vehicles to be refueled.

Setting Up a Refueling Site

Posting Signs

Once you have selected a suitable site, mark the perimeter of the refueling

area with signs that are readable from 50 feet. The signs must say

“FLAMMABLE” and “NO SMOKING WITHIN 50 FEET.”

Containment for Spills

Before conducting refueling operations, MFT operators should construct

diking by using dirt, sandbags, plastic sheeting, absorbent booms, or some

other method that will stop or slow the spread of a spill. Limiting the spill will

minimize the impact to the environment. When practicable, use the natural

terrain to direct potential spill to plastic lined pits or berms.

Refueling Procedures

General

MFTs must be operated in accordance with their respective Technical

Manuals (TMs). These are the minimum training qualifications necessary for

personnel to conduct refueling operations:

! Knowledge of fuel hazards and emergency procedures

! Knowledge of the proper PPE and how to use it

! Authorization and ability to move the vehicle being refueled

Operating Practices to Prevent Spills

Handling fuel can be very dangerous. Improper handling can result in spills,

fires, and explosions. Before conducting refueling and other fuel transfer

operations, review the following precautions to minimize spills and hazards.

The practices listed below do not replace the requirements of the vehicles -10

Technical Manual (TM).

Work Area Precautions

1. Eliminate any hazards and keep the work area free of equipment,

tools, lumber, debris, and other objects that may cause accidents.

2. Keep refueling equipment and supplies in good working condition.

3. Replace worn or broken parts immediately.

Refueling Precautions

1. Check all drains, outlets, valves, lines, fittings, issue/receiving

points, and around the tank area for leaks before, during, and after

all fueling operations. Equipment failure is the primary spill danger

during refueling: a high-pressure line break, loose/broken fittings or

valves, supply or vent line rupture, a vehicle accident, or by

overfilling a tank.

2. Ensure that the vehicle is turned off and that no one

remains in it during refueling and other fuel transfer

operations.

3. Carefully open hatches, vents, and valves, as pressure

may have built up within the system.

4. Ensure that the fuel attendant stays within 25 feet of

valves and

fittings for

the MFT and keeps an unobstructed view of the hoses,

connections, and vehicle being refueled.

5. Never perform refueling or other fuel transfer operations when

electrical storms threaten.

6. Provide a positive means to load a predetermined quantity of fuel

when bottom-loading an MFT vehicle.

7. Leave 1% headspace in every flammable or combustible liquid tank

or compartment for content expansion when temperatures rise.

Fire Precautions

1. Supply all MFTs with at least one portable fire extinguisher

rated 20-B, C or with two portable fire extinguishers

rated 10-B, C.

2. Always place fire extinguishers and firefighting equipment

in a safe location within easy reach.

3. If a fire occurs in a tank compartment, stop the flow of fuel, if

possible, and close the manhole cover.

Personal Protective Equipment Precautions

! Use PPE, such as gloves, apron, boots, goggles, and protective

clothing, when working directly with fuel.

! Wear cotton clothing with no metal zippers. NEVER wear nylon,

wool, or rayon clothing when handling petroleum products, as

static electricity can build up in such fabrics.

! If clothing gets soaked with fuel, thoroughly wet the clothes and

immediately remove them. If no water is available, hold a piece of

grounding equipment with both hands to ground yourself for a

moment before removing your clothing.

Managing Accumulated Rainwater

This section provides guidance for managing rainwater that may accumulate

in secondary containment systems.

Visually inspect the accumulated rainwater surface for the presence of an oily

sheen.

! If the water’s surface does not display an oily sheet, discharge it onto the

ground.

! If the water’s surface does display a visible oily sheen indicating fuel

contamination, perform the following actions:

Step 1. Obtain a closed-top 55-gallon DOT approved drum.

Step 2. Label the drum with a “Non-Hazardous Waste” label marked ‘FUEL

WATER WASTE’. Indicate the name of the unit and the date the

waste was placed in the container. Attach the fuel’s MSDS to the

drum in a clear plastic bag with tape or adhesive.

Step 3. Put on rubber boots, rubber gloves, safety goggles, and splash suit.

Remove the oil sheen by using absorbent pads, absorbent socks, a

skimmer or similar method and put it in the labeled drum. If you

cannot remove the sheen, then collect all of the water using a pail or

bucket and put it in the drum.

Step 4. Turn in the wastewater at the training installation. Do not take it

back to the home station.

Closing a Refueling Site

Follow these steps to close a refueling site.

Step 1. Inspect Refueling Area

1. Inspect the entire site for any leaks or spills as a result of the refueling

operation.

2. Look for stained or fuel-smelling soil and dead or stressed vegetation.

3. If any contaminated soils are identified, notify your commander and

clean up the site IAW step 3 below.

Step 2. Dismantle Containment Structures

1. If plastic, sandbags, bricks, or concrete blocks were used, remove them.

2. If a pit was dug, fill it in and regrade the area.

3. If an earthen berm was constructed, level it and spread the soil over the

site.

Step 3. Site Restoration

1. Before leaving the site, ensure that it is clean and the area is restored to

its original condition.

2. Don the proper PPE and dig up any contaminated soil. Place the soil in

an approved drum or other container. Properly containerize and label all

fuel wastes, stained or fuel-smelling soil and/or rainwater, used PPE,

and plastic liners.

3. Turn in the waste at the installation where the spill occurred. If refueling

occurred on public property, contaminated soil must be taken back to

the home station for disposal.

SPILL PREVENTION IN PARKING THE MOBILE FUEL TANKER

MFT operators must comply with state, local, and installation (training

areas) regulations when parking the fuel tanker. This section has been

prepared IAW 49 CFR 397.7. It explains the actions to take when parking at

a rest stop, home station, or the cantonment area.

Driver's Requirements

Complete the following actions when parking this MFT.

1. Park in a designated MFT parking area, if available, away from all

overhead power lines.

2. Block the wheels with chocks.

3. Display placards of the appropriate type for the fuel in the tank or, if

empty, the last type of fuel hauled. Placards must remain on the

vehicle unless it is cleaned of ALL residual matter (49 CFR 172.514).

Note: Purging the tanker or triple-rinsing it are examples of cleaning ALL

residual matter from the MFT storage volume. For the ARNG, a

MFT is considered empty when, while parked on a level surface,

no more fuel can be removed from the bulk storage tank using the

vehicles normal fuel unloading delivery system. This should leave

enough fuel in the MFT to ensure seals do not dry out and also

pose minimal threat to the environment.

4. Connect the required grounding wires for the vehicle or tank.

5. Do not park the MFT on or within five feet of the traveled portion of a

public street or highway, except when absolutely necessary.

6. If parking with fuel in the tank, check with your supervisor or Unit

Environmental Compliance Officer (UECO) for additional guidance.

OIL SPILL PREVENTION AND CONTINGENCY PLAN

SECTION 4

When In Maintenance

When this MFT is in maintenance for shop-level repairs and/or service (e.g.,

transmission, engine, etc.), the fuel storage tank must be empty. An MFT is

considered empty when, while parked on a level surface, no more fuel can

be removed using the vehicle’s normal unloading delivery system.

Mobile Fuel Tankers at sites that do not have approved secondary

containment structures may have their bulk storage tanks filled with fuel up

to three calendar days prior to Annual Training or an Individual Duty Training

(IDT) weekend, and they can remain parked at their Home Station. The

MFT’s vehicle records must indicate the date the bulk storage tank was

filled. MFTs will be in the “transport” status under Department Of

Transportation (DOT) regulations. These MFTs do not have to be parked in a

secondary containment structure. However, all efforts will be made to ensure

the MFTs are parked in a safe condition (away from water sources, or

adjacent property, and on level land with a spill containment kit available).

All convoy vehicles should have full fuel tanks prior to the start of the convoy.

However, full MFTs may be used to fuel convoy vehicles prior to the start of

the convoy. The MFT may also be used to fuel vehicles during the convoy to

the Training Site. Secondary containment for the MFT is not required for

these operations. These actions are considered to be Refueling On the Move

(ROMs), and are not an EPA regulated activity. Upon arrival at the Training

Site, parking and refueling operations will be conducted according to

installation regulations and Army requirements. The fuel transported from

the Training Site back to Home Station in the MFT should be only the

necessary volume for distribution during the convoy so that the MFT is

returned empty.

HYDROGEOLOGY OF PARTS OF THE CENTRAL PLATTE AND LOWER LOUP 

NATURAL RESOURCES DISTRICTS, NEBRASKA

By J. M. Peckenpaugh and J. T. Dugan

ABSTRACT

Water-level declines of at least 15 feet have occurred in this 

heavily irrigated area of central Nebraska since the early 1930's, and 

potential for additional declines is high. To test the effects of 

additional irrigation development on water levels and streamflow in the 

area, computer programs were developed that represent the surface-water 

system, soil zone, and saturated zone of the hydrogeologic system. A 

two-dimensional, finite-difference ground-water flow model of the 3,374 

square-mile study area was developed and calibrated using steady-state 

and transient conditions, and three management alternatives were examined. 

Results indicate that significant additional water-level declines will 

occur even if there is no additional ground-water development.

The first management alternative examined is diversion of an 

additional 125,000 acre-feet of water per year from the Platte River. 

This alternative would have a substantial effect on flows in the Platte 

River. During a water year in which flows are similar to those in 1957, 

months of zero streamflow at Grand Island and near Duncan would increase 

from the historical 2 and 3, respectively, to 7. Projected declines in 

ground-water levels based on this alternative and the 1976 level of 

ground-water development are small. After 5 years of such low flows, in 

36 model nodes (997.4 acres per node) water levels would decline more 

than 5 feet, and the maximum decline would be 10.7 feet.

The second alternative examined is to allow no new ground-water 

development after 1980, but to apply irrigation water at five different 

rates ranging from a low of 80 percent of consumptive-irrigation requirements 

(CIR) to a high of 16.0 inches per year (about 125 to 150 percent of 

CIR) for the western part of the study area. With a medium application 

rate of 100 percent CIR, water-level declines of more than 20 feet are 

projected for 20 percent of the study area by the year 2000; maximum 

projected declines are between 60 and 79 feet. For the same application 

rate, maximum projected declines by the year 2020 are between 100 and 

119 feet.
The third alternative is to allow potentially irrigable but unirrigated 

land to be developed at an annual rate of 2, 5, and 8 percent and to 

apply irrigation water at 80, 100, and 120 percent of CIR. Compared to 

water levels of August 31, 1976, maximum projected declines by the year 

2000 for each of the development rates and for 100 percent of CIR are 

between 60 and 79 feet.

Thirty variations of the last two alternatives were evaluated, and 

maps showing results of 17 are included in this report. Also included 

are 10 maps delineating and describing the hydrogeologic characteristics 

of the aquifer.

Modeling results indicate that water levels will decline. The 

declines in shallow-water areas will increase the amount of evapotranspiration 

salvage, will cause more surface water to move into the aquifer, and 

will cause less ground water to move into the streams.

INTRODUCTION

During the past several decades, the availability of ground water 

for irrigation has enabled the farmers and ranchers in much of Nebraska 

to greatly increase productivity. This has been particularly true in 

this study area (fig. 1). Irrigation itself is not new to the area; 

both the Platte and the Loup Rivers, between which the study area lies 

in central Nebraska, have been used as sources of surface water for 

irrigation since the 1890's. However, limitations on the availability 

of surface water, the widespread availability of ground water and other 

factors spurred the use of and dependence on ground water for irrigation, 

so that now part of this area has the highest irrigation-well density of 

any comparable area of the State.

Ground-water supplies, while rechargeable in most instances, are 

not infinite, and in several areas of the State intensive withdrawals of 

ground water severely strain the capacity of the ground-water system so 

that water levels are declining. Although no severe problems of waterlevel decline have as yet been identified, progressive water-level 

declines are occurring in parts of the study area. Declines of at least 

15 feet have been measured in parts of Dawson and Buffalo Counties.

The potential for additional water-level declines is high for 

several reasons. First, current ground-water pumpage for irrigation, 

which caused the present declines, will continue. Second, within the 

area, additional development that will accelerate current declines is 

likely. Finally, additional ground-water irrigation west of the study

area and additional surface-water diversions from the Platte River may 

result in additional water-level declines, but only if these developments 

reduce the annual flows of the Platte River within the study area below 

a critical level. Fred Otradovsky of the U.S. Bureau of Reclamation, 

Grand Island, Nebr. (personal communication, 1983), believes a reduction 

of 50 percent in streamflow would cause less than a 1-foot drop in river 

stage. Such a drop in stage would produce additional but only small 

declines in ground-water levels.

The continuation of additional water-level declines is predictable; 

however, the location and magnitude of future declines are less predictable. 

Realizing this, the Central Platte and the Lower Loup Natural Resources 

Districts, in 1977, entered into an agreement with the U.S. Geological 

Survey to do a quantitative hydrogeologic study of the area. The results 

of this study are to serve as a basis for testing the effects of various 

management alternatives for additional irrigation development on water 

levels and streamflow in the study area and are the subject of this 

report.

Purpose and Scope

There are two principal purposes for this study. The first is to 

describe the hydrogeologic system of the study area. The second is to 

develop and demonstrate a capability for evaluating, quantitatively, the 

effects of different management alternatives on water levels and on 

streamflow in the study area.

In this study, the different components of the hydrologic system -- 

surface-water system, soil zone, unsaturated zone, and saturated zone -- 

were analyzed using mathematical programs whenever possible. These 

programs are linked to form a single model of the system so that the 

responses of the entire system to variations imposed on it can be simulated 

mathematically. The surface-water system is included in the model only 

to the extent necessary to determine the effects of surface water on 

recharge to the ground-water reservoir, or the converse.

Few new field data were obtained for this study. Hydrologic and 

geologic data obtained by previous investigators were reviewed and 

reinterpreted using numerical techniques. Also, large amounts of data 

on land use, climate, and water use were obtained from others. Such 

data are essential input in evaluating the effects of different management 

alternatives on the water resources of the study area.
Management alternatives for evaluation were selected in consultation 

with the Central Platte and the Lower Loup Natural Resources Districts. 

A total of 30 variations of alternatives were examined. Of these, 

results of the 17 most representative variations are shown in maps and 

tables of this report.

Previous Studies

Several previous investigations were made to determine the geology 

and hydrology of this area. Three cover nearly all of the present study 

area that lies within the Platte Valley -- the flood plains and terraces 

between the Platte and Loup Rivers -- and provide historic records, such 

as those of water levels, critical to this study. Reports on studies of 

smaller areas provide insight into special problems of local interest. 

Most of the previous studies were limited to terraces and flood plains 

of the Platte and Loup Rivers.

Lugn and Wenzel (1938), in an early study of south-central Nebraska, 

describe in detail the geology and hydrology of nearly all of the Platte 

Valley included in this study area. They discuss the origin, character, 

and thickness of the Pleistocene water-bearing materials in the Platte 

Valley, present logs of about 75 test holes, provide maps showing depth 

to water from the land surface and elevation of the water table during 

the summers of 1931 and 1932. They also discuss development of both 

surface- and ground-water irrigation up to 1932.

Wenzel (1940) investigated declining water levels beneath the city 

of Grand Island. He concluded that the cause was excessive pumping from 

wells too closely spaced and recommended that wells be installed outside 

the city so that pumping stress could be distributed over a larger area.

Several studies were made in the 1940 T s and 1950 T s as part of the 

program of the Department of the Interior for development of the Missouri 

River Basin. Waite and others (1949) supplemented existing hydrogeologic 

information on the Platte Valley from North Platte to Fremont, Nebr. 

Maps were presented that show net changes in water levels from 1930 to 

1939 and from 1939 to 1946 and that show the elevation and configuration 

of the water table in March 1947.

Several areas investigated under the Missouri River Basin Program 

were being considered for project development by the U.S. Bureau of 

Reclamation. These areas cover a major part of the present study area. 

Keech (1952) describes the ground-water resources of the Wood River Unit 

from near Kearney to near Wood River, Nebr., a 233 square-mile area 

proposed for a balanced surface- and ground-water irrigation system.
Sniegocki (1955) describes the ground-water resources of the Prairie 

Creek Unit, a 650 square-mile area between the Loup and Platte Rivers 

extending from near Grand Island to Columbus. Schreurs (1956) describes 

the geology and ground-water resources of Buffalo County and parts of 

adjacent Dawson and Hall Counties, where consideration also was being 

given to development of a balanced surface- and ground-water irrigation 

system. Keech and Dreeszen (1964), in a report on the availability of 

ground water in Hall County, include a map showing the elevation and 

configuration of the water table in 1961. Their study, however, was not 

a part of the Missouri River Basin Program.

Several hydrogeologic studies have been conducted in the Loup River 

basin, but only one included any of the present study area. In that 

one, Hyland and Keech (1964) describe the ground-water resources of the 

Cedar Rapids Division in southeastern Howard and northwestern Merrick 

Counties.

More recently, hydrogeologic studies have been conducted for parts 

of the study area using ground-water flow models. Marlette and Lewis 

(1973) and Marlette and others (1974) discuss the development and 

results of a study using such a model for the Platte River valley of 

Dawson County. Also, Lappala and others (1979) used such a model in a 

study of the entire Platte River basin, which included all of the study 

area.

Bentall (1975a) describes the physiography, geology, soil, and 

agriculture of a large part of the study area. Bentall (1975b) also 

describes the hydrology of the study area and upstream reaches of the 

Platte River. In his reports, Bentall reviews previous studies and 

discusses the above items as they relate to a proposed surface-water 

diversion project in this area.

General Methodology

The general methodology for this study was first to subdivide the 

hydrogeologic system into four components -- surface-water system, soil 

zone, unsaturated zone, and saturated or ground-water zone. Computer 

programs were developed or obtained to represent each of the components 

except the unsaturated zone, for which this was not possible.

A ground-water flow model was developed to represent the hydrogeologic 

conditions in the area over time. Hydrogeologic data, necessary for the 

model, were obtained mainly from previous investigations. However, data 

on recharge and consumptive-irrigation requirements (CIR) were obtained
either from existing files or were generated, in part, through use of 

computer programs. The model was then calibrated using the above data, 

and several management alternatives were simulated with the calibrated 

model.

The hydrogeologic data are those needed to describe the characteristics 

of the ground-water system. They include but are not limited to hydraulic 

conductivity, specific yield, base of the aquifer, and elevation of the 

water table. Recharge and CIR data, hereafter called "recharge-CIR 

data", are those necessary to generate data on deep percolation and 

discharge required for the ground-water flow model. Recharge-CIR data 

provide information on soils, climate, water requirements of plants, 

land use, irrigation-well distributions, acres irrigated per well, 

surface-water irrigation and seepage, and stream flow.

and Lower Loup Natural Resources Districts during this study. Also 

appreciated is the assistance of representatives of the U.S. Bureau of 

Reclamation and of the Nebraska Natural Resources Commission in obtaining 

data and programs. Special thanks are extended to Eric G. Lappala, the 

first project leader of this study, who worked with the cooperators in 

developing the study, developed numerous procedures, programs, and data 

used in the study, and provided technical guidance on many occasions.

PHYSICAL SETTING

The physiography, geology, climate, soils, natural vegetation, and 

land use of the study area are extremely important in influencing the 

surface-water and ground-water developments of the area. These features 

have also been instrumental in determining urban and rural development 

and the general economic systems of this area, which are strongly dependent 

upon agriculture, especially irrigated agriculture.

Location and Extent

The study area is shown in figure 1. It comprises all of the 

Central Platte Natural Resources District (NRD) north of the Platte 

River and all of the Lower Loup NRD south of the South Loup, Middle 

Loup, and Loup Rivers. The study area was extended 3 miles west of the 

western borders of Dawson and Custer Counties so that modeling errors 

near these borders could be minimized. The study area includes 3,374 

square miles. Its maximum east-west distance is 155.7 miles and its 

maximum north-south distance is 59.3 miles.

Physiography

The study area lies within the High Plains section of the Great 

Plains Province. From central Hall County eastward, the study area does 

not fit the standard geologic description of the High Plains because the 

Tertiary materials are absent. A substantial Quaternary mantle is 

present in this area, and there is no surficial difference between areas 

where the Tertiary materials are present or absent.

Significant contrasts exist between the topography in the valleys 

and uplands of the study area. Three major topographic types are present: 

(1) uplands, (2) terraces, and (3) flood plains. Figure 2 delineates 

the location of these types. This figure was developed from soil maps 

of the area (Hayes and others, 1924, 1925, 1926, 1928; Veatch and Seabury, 

1918; Paine and others, 1929).

The uplands are predominantly loess-mantled, highly dissected, and 

generally not suitable for sustained cultivation. However, relatively 

large tablelands are found in Custer County and small, flat interfluves 

occur in Dawson and Buffalo Counties. Both of these land forms support 

irrigated agriculture. Significant areas of the uplands and high terraces 

in southwestern Custer County, southeastern Howard County, and northern 

Merrick County are mantled with dune sand stabilized by grass. Most of 

this sandy material exists as a relatively thin veneer over loess (windblown silt) or as silty deposits that have drifted in from the Sand 

Hills or other nearby sources of sand.

The terraces and flood plains are the result of entrenchment of the 

Platte and Loup Rivers and their tributaries at elevations from 50 to 

150 feet below the uplands and tablelands. The Platte River was superimposed 

on the existing Tertiary landscape, and Quaternary materials were deposited 

during periods of aggradation, while some of these materials and other 

units were eroded during periods of degradation. The terraces are 

primarily covered by a loess mantle with a sandy or gravelly substratum. 

The loess in some areas is reworked with sandy alluvium; whereas, in 

other areas it is eroded so that the terraces are covered by a silty and 

clayey alluvium.

The flood plains along the Platte River gradually blend into the 

terraces. Those along the north side of the river are more extensive 

than those on the south side. The flood plains in all but the downstream 

reaches of the Wood and South Loup Rivers are so narrow that they are 

not mappable at the scale used in figure 2. The flood plain of both 

streams widens toward the east, that of the Wood River as it merges with 

the flood plain of the Platte River and that of the South Loup River as 

it nears its confluence with the Middle Loup River. The flood plains

are usually covered by sandy, silty, and clayey materials that reflect 

the energy, or carrying capacity, of the moving water and their depositional 

history. However, some of the terraces and flood plains, near Shelton 

and west of Grand Island, are mantled with dune sands.

The width of the Platte Valley varies throughout the study area. 

It is about 12 miles wide east of Gothenburg, but narrows to about 6 

miles near Elm Creek and to 3 miles west of Kearney. From there to 

western Merrick County it widens to a maximum of 17 miles. The terraces 

and flood plains of the Middle Loup and Loup Rivers, beginning in western 

Hall County, increase significantly in width from upstream reaches in 

which the valley is 1 to 4 miles wide. From Merrick County eastward to 

the confluence of the Loup and Platte Rivers, the Loup and Platte River 

valleys merge but are separated in two areas by uplands where dune sands 

have been deposited forming sandhills.

Land-surface elevation of the study area varies from 3,088 feet in 

the west to 1,405 feet in the east. From west to east, the Platte 

Valley declines from 2,400 feet to about 1,550 feet, which is an average 

slope of 7 feet per mile. West of Kearney the topography is rougher and 

has a steeper riverward slope than east of Kearney. From Merrick County 

eastward, the topography is nearly level, having slopes only slightly 

greater than those of the Platte River, except in northern Merrick 

County where rough sand dunes occur. Throughout most of the valley, the 

terraces merge gradually into the flood plains.

Geology

Quaternary deposits comprise the land surface in the study area and 

form the most significant portion of the saturated zone from the middle 

of Hall County eastward. These deposits are sands, gravels, silts, and 

clays of fluvial origin and silts and clays of eolian origin. The 

thickness of these deposits varies from about 20 feet in the Platte 

Valley of southwestern Buffalo County to about 350 feet in the upland of 

eastern Dawson County.

In the study area, several episodes of fluvial and eolian deposition 

were followed by periods of erosion and soil formation during Quaternary 

time. These events were related to the advancing and retreating (melting) 

of continental ice sheets in eastern Nebraska. These ice sheets blocked 

the valleys of eastward-flowing streams and diverted their flow southward 

and southeastward along the ice margins.

10
The diversion of these streams lowered their gradients and reduced 

their sediment-carrying capability. The streams aggraded their valleys 

and eventually constructed alluvial plains in front of the ice sheets. 

After melting of the ice sheets, the sediment load of these streams 

decreased. The level to which the streams could erode valleys into the 

alluvial plain lowered, and subsequent erosion produced a new landscape 

of valleys and uplands.

Within each depositional sequence, the lower part is generally 

coarse-textured sediments, sands and gravels, while the upper part is 

finer-textured sediments, silts and clays, which, in some cases, were 

largely removed during the erosional intervals. Thus, in many places 

the sand and gravel deposits of one sequence occur vertically adjacent 

to those of another sequence, or are separated only by thin layers of 

clay or silt.

The Quaternary deposits in the upland areas contain thicker intervals 

of silts and clays than in the flood plains and terraces, because the 

silts and clays in uplands were less subject to removal during erosional 

intervals. As a result, thick units of silts and clays, primarily 

loess, still remain beneath the uplands. However, only a few feet of 

loess remain beneath the flood plains and terraces because most of it 

has been removed by erosion or has been reworked into alluvium. The 

loess and loess-like alluvial deposits are the most extensive surface 

deposits in the study area.

Upper Quaternary dune sand covers parts of southwestern Custer 

County and extensive areas between the Platte and Loup River valleys in 

Hall, Merrick, Howard, Nance, and Platte Counties. These dune sands 

usually rest on loess. In several small areas, dune sand has been 

reworked from existing sand deposits to form areas of rough topography.

Alluvium, consisting primarily of reworked loess, mantles most 

terraces in the Platte Valley. Its deposition probably alternated with 

the deposition of silt and fine sand blown from the loess-mantled uplands. 

The thickness of the alluvium ranges from 50 feet, adjacent to the 

uplands, to zero feet at the margins of the terraces and flood plains. 

Alluvium extends up the Wood River valley and other stream valleys that 

drain the uplands.

The Tertiary Ogallala Formation lies immediately below the Quaternary 

deposits in the study area from the middle of Hall County westward. The 

Ogallala Formation, fluvial in origin, consists of semi consolidated 

calcareous silt, sand, and sandstone with some interbedded marly zones, 

and with a basal gravel at some locations. The thickness of the Ogallala 

Formation ranges from zero feet at its eastern extent in Hall County to 

over 540 feet in Dawson and Custer Counties and is related to the topography 

of the underlying Cretaceous bedrock.

11
Cretaceous bedrock units, which are thick beds of shale with some 

thinner beds of shaley chalk and chalk are not considered hydrologically 

important to this study. These units directly underlie the Ogallala 

Formation and the Quaternary deposits where the Ogallala Formation is 

not present. The bedrock surface, which was produced by erosion, consists 

of valleys and intervalley ridges that are unrelated to the present land 

surface. The total relief of this buried surface is about twice the 

present land surface.

Climate

The climate of the study area, which has irregular precipitation, 

low to moderate humidity, hot summers, and severe winters, is typical of 

regions within large continents in the mid latitudes. The average 

temperature of the warmest month, July, ranges from 75° to 78° F across 

the study area, whereas, that of the coldest month, January, ranges from 

22° to 26° F. Extreme temperatures range from -40° F to 117° F. The 

winters are slightly milder in the western part of the study area, and 

the summers are warmer and more humid in the eastern part. The growing 

season (period between killing frosts) averages from 150 days in the 

west to 160 days in the east.

Variability characterizes precipitation in the study area. Mean 

annual precipitation from 1931 to 1976 ranged from about 19.3 inches in 

the western part to about 24.8 inches in the extreme east. Annual 

precipitation frequently varies from the mean by 50 percent. Drought 

periods can last for several years. Noteworthy droughts since the last 

century occurred in the mid-1890's, 1930's, mid-1950's, and mid-1970's. 

The dry periods were accompanied by warmer-than-average temperatures, 

and increases in desiccating winds increased evapotranspiration losses 

and intensified drought conditions. Frequent short-term deficiencies of 

precipitation during the growing season often have serious effects on 

crop production. Although from 70 to 80 percent of the annual precipitation 

normally occurs during the growing season of April through September, it 

often is irregularly distributed. Precipitation generally is uniformly 

distributed over the study area from September through April because of 

its cyclonic or frontal origin. From May through August; however, most 

precipitation is the result of convective activity (thunderstorms); 

thus, it is distributed nonuniformly.

Potential evapotranspiration (PET) in the study area exceeds average 

annual precipitation. Although precipitation ordinarily exceeds PET 

from October through May, PET exceeds precipitation from June through 

September. Low humidity, periods of persistent winds, and a high incidence 

of sunshine contribute to high PET rates.

12
Soils

The soils of the study area are indicative of the climatic, geologic, 

and biotic factors that influence their development. The major soil 

characteristics resulted from the development of the soils on loess, or 

loess-like fluvial silts, in a semiarid to subhumid climate with a 

grassland regime. Development under such conditions produced dark, 

granular, relatively thin topsoils. Several of the soils possess an 

argillic horizon, which is an accumulation of clays in the upper subsoil 

resulting from downward movement of fine-grained materials (clays) 

during soil development.

The soils and topography of an area are strongly related. This is 

apparent from a comparison of the soils and topographic-types maps 

(fig. 3 and 2, respectively). On figure 3, the soils in the study area 

have been grouped according to hydrologic properties. The following 

discussion illustrates the relationships between soil groups and topography.

Dissected uplands are composed of soils possessing minimal development 

that are formed on loess. These soils comprise the Coly-Colby-Uly-Ulysses 

group (map symbol "F" on fig. 3).

Level uplands and high terraces exhibit much deeper soil development. 

They are formed on loess and reworked loess, with the major group being 

Holdrege-Hord-Hall-Kenesaw (map sumbol "E"). The substrata of some 

terrace soils may be sandy alluvium. These soils have moderate to low 

permeabilities and are well suited for irrigation.

Extensive areas of the uplands and terraces are mantled with 

highly permeable soils as a result of their formation in sandy alluvium 

or eolian sands. The Ortello-Blendon group (map symbol "D") and the 

Valentine-Thurman group (map symbol "G") are these types of soils.

Parts of the lower terraces that formed in loess and silty alluvium 

have a well-defined claypan and are slowly permeable and, in places, 

poorly drained. These soils form the Wood River - Silver Creek group 

(map symbol "H"). The Inavale-Loup-Alda-Platte group (map symbol "A") 

and the O'Neill-Sarpy group (map symbol "I") also occupy the lower 

terraces, but have been derived from sandy materials and are highly 

permeable and well drained.

Flood-plain soils include a variety of textural types ranging from 

silty or clayey to sandy, with the more sandy soils predominating. The 

Gibbon-Lamo group (map symbol "C") occupies clayey bottomlands; whereas, 

the Warm-Gass-Leshara group (map symbol "B") occupies sandy bottomlands. 

All of these soils are poorly drained as a result of seasonal high-water 

tables.

The agricultural potential of most soils in the study area is high. 

Only the soils of the dissected uplands, which are thin and sloping, and 

of certain bottomlands, which are poorly drained because of frequent 

high-water table conditions or presence of a clay layer, have low agricultural potential.

Natural Vegetation

The natural vegetation of the study area has largely been replaced 

by cultivated crops. Only in the dissected uplands and along the streams, 

where conditions are not conducive to cultivation, do large tracts of 

natural vegetation remain.

The natural vegetation consists primarily of grasslands known as 

the mixed prairie. Weaver and Albertson (1956) divide the natural 

vegetation of the study area into three principal plant communities. 

Short grasses capable of thriving with low soil moisture predominate on 

the hilltops of the uplands. Tall and midgrasses of the true prairie 

occupy the bottoms, low terraces, and lower slopes of the hills where 

more moisture is available. Mixed short and taller grasses occupy the 

side slopes between hilltops and bottoms.

The mixed prairie gradually gives way to the true prairie to the 

east of Grand Island. Here the taller grasses become dominant as mean 

annual precipitation increases.

Most of the grasses, particularly the short varieties, have extensive 

root systems in relation to top growth. Roots often extend 4 to 7 feet 

downward with significant lateral expansion. Many of these grasses 

produce dense, tough sod that stabilizes the soil and limits runoff. 

Consumptive water requirements of the native grasses are nearly the same 

as those of legumes.

Along permanent streams, woodlands are present that contain both 

natural and introduced species. Many of these species, such as willows, 

are phreatophytes that have high consumptive water requirements.

15
Land Use

Agriculture is the predominant land use for at least 90 percent of 

the study area. Forty percent of the agricultural lands are unsuitable 

for cultivation and are left as rangeland. Most of the remaining agricultural lands are irrigated or are potentially irrigable. More than 

600,000 acres in the study area are irrigated with ground water from 

more than 12,000 wells (Nebraska Department of Agriculture, annual 

report for 1976). About 44,000 acres in Dawson and Buffalo Counties are 

irrigated with surface water.

Land use within the study area, for selected years from 1931 through 

1976, is listed in table 1. Information for this table was developed 

from county data on harvested crop acreages published by the Nebraska 

Department of Agriculture (annual reports, 1931-1976). Even though the 

information is for entire counties, it represents, adequately, land use 

in the study area.

Alfalfa acreage has not changed significantly during the period of 

study. Approximately 20 percent of the alfalfa in Dawson and Buffalo 

Counties receives supplemental irrigation water, and large acreages of 

alfalfa are subirrigated in the high-water table areas of the Platte 

River valley.

The acreage of small grains has declined significantly since the 

1930's from about 20 percent to about 5 percent of the land area. 

Virtually no small grain is irrigated.

Acreages of irrigated row crops increased over time at the expense 

of dryland row crops and small grains. In Hall and Merrick Counties, 

irrigated row crops occupy about 50 percent of the land area. Total 

acreages of dryland and irrigated row crops increased since the 1930's 

for Platte, Hall, and Merrick Counties, but decreased, or remained about 

the same, for the other counties.

The principal row crop of both irrigated and dryland is corn; other 

row crops, in order of decreasing acreages are soybeans, grain sorghum, 

sugar beets, and potatoes. Most of these row crops, with grain sorghum 

being the principal exception, are irrigated.

Pasture and range acreages increased over time for most of the 

study area. Only in Merrick County have acreages of pasture and range 

decreased. During this period of 1931 to 1976, fluctuations in the 

acreages of pasture and range were numerous.

Short-term increases and decreases in some land-use categories 

usually represent either abnormal climatic conditions, significant 

variations in crop prices, or governmental policy changes. Long-term 

changes in some land-use categories reflect variations in ground-water 

irrigation development. The flood plain and terrace lands were irrigated 

for crop production earlier than the uplands. Thus land-use changes 

occurred first in the valleys and later in the uplands. The land-use 

changes also reflect the economics of producing and marketing different 

crops.

DESCRIPTION OF THE HYDROGEOLOGIC SYSTEM

For this study, the hydrogeologic system is divided into four 

components: Surface-water system, soil zone, unsaturated zone, and 

saturated or ground-water zone. Computer programs have been developed 

to represent and describe three of these components; however, there are 

neither appropriate data nor an adequate computer program to represent 

the unsaturated zone satisfactorily.

Surface-Water System

The surface-water system consists of streams and canals. This 

system and the ground-water zone are interrelated where the aquifer is 

connected hydraulically with streams and where canals provide passageways 

either for diversions or return flows to the streams.

Streams

Most of the major streams in the study area flow nearly parallel to 

the Platte or Loup Rivers. In areas having shallow water tables, several 

streams, particularly in Hall and Merrick Counties, frequently cease to 

flow during the irrigation season as ground-water pumpage lowers water 

levels. Other streams have no base flow and carry only surface runoff 

from precipitation.

Live reaches of the streams in the study area, that is, reaches 

interconnected with the saturated zone and in which there is perennial 

flow, are shown on figure 4. Each square, or node, on this model grid 

map represents an area of 6,525 by 6,525 feet, or 997.4 acres, and is 

identified by a row and column number. The nodes marked with "X" represent 

stream nodes and have live streams touching or flowing through them. 

For modeling purposes, the entire node is treated as a stream. Nodes 

corresponding to intermittent reaches are not marked with "X". Neither 

are the nodes corresponding to streams that are constantly flowing but 

not connected with the saturated zone.

Stream reaches can either gain water from the ground-water system 

or lose water to it at different times during the year. Some reaches of 

the Platte River, for example, gain water from the ground-water system 

at certain times of year, but lose water to the ground-water system at 

other times. Streamflow in the Loup River system is relatively constant 

because it is derived almost entirely from ground-water discharge that 

is nearly constant throughout the year. Thus, in most of the Loup River 

system, the streams are gaining ones.

In the ground-water flow model for this study, average rates of 

streamflow were used whenever possible. However, the level of detail 

necessary in the model for handling the stream-aquifer relationship 

along the Platte River requires the use of streamflow rates for each 3- 

month irrigation pumping period (from June through August) and for each 

9-month nonirrigation pumping period (from September through May).

Figure 5 is a schematic of the surface-water system showing the 

live streams, stream-gaging sites, canal diversions, and canal returns. 

The average annual flows at stream-gaging sites and of inflow from 

tributary streams are indicated. Also indicated are the average annual 

canal diversions and returns.

Base flows, calculated for stream-gaging sites at which flows are 

neither regulated by upstream reservoirs nor affected by canal diversions 

or return flows, are given in table 2. These flows were calculated by 

averaging streamflows in October, November, and December for the period 

of record. Streamflows caused by surface runoff from heavy precipitation 

were excluded in the calculations.

Seepage measurements were performed to supplement the base-flow 

data. Both base-flow data and seepage data indicate in what stream 

reaches and in what amounts water moves as seepage through the streambeds 

into the underlying saturated zone, or the converse. The results of 

seepage measurements for the Loup River system, Prairie Creek, Silver 

Creek, Wood River, and Warm Slough are listed in table A of "Additional 

Information."

Data on average streamflows, base flows, and seepage gains or 

losses help improve our understanding of the stream-aquifer relationships. 

For example, streamflows in the Wood River have declined since the 

1930 T s, and the number and lengths of live reaches of this stream have 

also decreased. Analysis of flow, seepage, and ground-water pumpage 

data indicate that these changes are related to ground-water development 

near the Wood River. Decreases in streamflow also have occurred in 

Prairie and Silver Creeks because of ground-water development and drainage 

of high water-table areas. Effects of ground-water development on the 

Loup River system, however, appear to have been relatively minor.

2 Stream gage is outside study area.
Effects of ground-water development in the study area on flows in the 

Platte River are masked by the regulation of flow from upstream reservoirs 

along the Platte River and its tributaries.

Canals

In the study area, four canals currently are used for irrigation. 

These canals, from west to east on figure 5, are the Gothenburg, Cozad, 

Dawson County, and Kearney Canals. All were in full operation prior to 

1931, as was the Elm Creek Canal, abandoned in 1963. The Kearney Canal 

is used for hydroelectric-power generation. Until 1974, this was true 

also of the Gothenburg Canal. Figure 5 shows the main canals, but not 

the laterals or field-distribution systems.

Other canals either divert or return water to the south side of the 

Platte River and thus are outside the study area. These include Jeffrey 

Power Return and Johnson Power Return of the Tri-County Canal, Thirtymile 

Canal, Sixmile Canal, and Orchard and Alfalfa Canal. The Loup River 

Canal, also outside the study area, diverts water from the north side of 

the Loup River. Data on averages of water diverted or returned and on 

acres irrigated are given in table 3. As for streamflows previously 

discussed, annual canal flows were divided into a 3-month irrigation 

pumping period and a 9-month nonirrigation pumping period for use in the 

ground-water model. Flow volumes of the canals were evenly divided 

between these two pumping periods for each year from 1931 through 1976.

Soil Zone

The soil-zone component of the hydrogeologic system consists of the 

soils extending from the land surface through the plants' root systems. 

Of the water from precipitation and applied irrigation that infiltrates 

the soil zone, some is stored within the soil zone, some is withdrawn 

from the soil zone by evapotranspiration, some percolates to drains and 

is carried away as surface runoff, and some percolates to the underlying 

unsaturated zone or directly to the saturated zone, if no unsaturated 

zone exists.

Hydrologic Properties of the Soils

The soils in the study area have been delineated into nine soil 

groups (fig. 3) based on hydrologic properties of the soils. Each soil 

group was differentiated by soil texture, topographic position, slope, 

available water capacity, and average profile permeability of the soils. 

A listing of the hydrologic properties for the soil groups is provided 

in table 4. The source materials for information on these properties 

are available in published form from the Soil Conservation Service.

24
The available water capacity and the average profile permeability 

are important parameters in determining the amount of water stored in 

the soil and the amount that percolates downward to the saturated zone. 

Soils with higher permeabilities allow the water to move downward more 

rapidly than soils with lower permeabilities. Also, soils with high 

permeabilities have low available water capacity, which is the capacity 

of the soil to hold water for use by plants. The available water capacity 

is essentially the inverse of permeability. Thus, soils with high 

permeabilities and low available water capacities have a high potential 

for recharging the saturated zone, but soils with low permeabilities and 

high available water capacities, because they hold more water in the 

soil profile, have a low potential for recharging the saturated zone.

Infiltration of water and surface runoff are important in determining 

the amount of water stored in the soil profile and the amount recharged 

to the saturated zone. Soils with higher permeabilities normally have 

higher infiltration rates and lower surface runoff rates than soils with 

lower permeabilities. However, the intensity of rainfall, the amount of 

water in the soil profile, the vegetation cover, and whether the ground 

is frozen also influence infiltration rates.

Water Requirements of the Vegetation

Because different types of plants have different water requirements, 

it is necessary to distinguish between natural and cultivated vegetation 

and between the types of cultivated crops. Water requirements of landuse groups in table 1 in decreasing order are: irrigated alfalfa; 

dryland alfalfa (alfalfa and tame hay); irrigated row crops (corn, 

soybeans, grain sorghum, sugar beets, and potatoes); dryland row crops; 

pasture and range (fallow, urban lands, farmsteads, roads, woodlands, 

and predominantly pasture and range); and small grains (wheat, oats, 

barley, and rye).

Input to and Output from the Soil Zone

Precipitation and water applied in irrigation are inputs to the 

soil zone; whereas, evapotranspiration, surface runoff, and deep percolation 

are outputs from the soil zone.

Monthly precipitation data from 15 weather stations for the period 

January 1931 to December 1976 were compiled for this study. Missing 

monthly precipitation data were estimated from two or three surrounding 

weather stations using simple linear regression. Locations of these 15 

weather stations are shown on figure 3, and the average annual precipitation 

for each station is listed in table 5.

Polygons (fig. 3) were constructed around each weather station 

using the Thiessen method (Linsley and others, 1958) to areally distribute 

the point measurements of precipitation. The area within each polygon 

is assumed to receive the same monthly precipitation as the weather 

station.

The study area contains both lands that are irrigated with surface 

water and with ground water. Those irrigated with surface water, the 

distribution of which has not changed appreciably since 1970, are all in 

Dawson and Buffalo Counties; those irrigated with ground water are 

dispersed throughout the study area. Figure 6 shows the distribution of 

the lands irrigated with surface water in 1970, and figure 7 shows the 

distribution of all lands irrigated in 1980, whether by surface water or 

ground water.

The amount of irrigation water applied depends on land use, varying 

with type of crop grown, as previously discussed. Where lands are 

irrigated with surface water, approximately 50 percent of the water 

diverted into canals is assumed to percolate from the canals to the 

saturated zone; the remaining 50 percent is applied to the crops (Fred J. 

Otradovsky, U.S. Bureau of Reclamation, personal commun., 1979).

The largest component of discharge from the soil zone is evapotranspiration (ET). The Jensen-Haise procedures for calculating potential 

evapotranspiration (PET), which are described by Jensen, Wright, and 

Pratt (1969) and Lappala (1978), were used for this study. The PET data 

were used with appropriate crop coefficients, which are monthly ratios 

of actual ET to PET, to obtain the ET values for the different crops. 

Additional details on the ET procedures will be given in the section on 

recharge-CIR.

The other components of discharge from the soil zone -- deep percolation 

(recharge) and surface runoff -- are discussed further in the section on 

recharge-CIR.

Unsaturated Zone

The unsaturated zone extends from the soil zone to the saturated 

zone, or ground-water zone. Water in the unsaturated zone may move 

downward, upward, or laterally, and it may be stored for limited periods. 

The physics of water movement within the unsaturated zone is complex and 

not completely understood. For this study the unsaturated zone is 

treated simplistically as a conduit through.which water moves upward and 

downward with no storage. Major assumptions are that all water leaving 

the soil zone reaches the ground-water zone, that water moving up from 

the ground-water zone through the unsaturated zone reaches the soil 

zone, and that lateral movement of water within the unsaturated zone is 

negligible.

Saturated Zone

The saturated zone, also called the ground-water zone, hereafter 

will be referred to as the aquifer. It extends from the water table to 

the base of the lowest coarse-grained materials -- sand or gravel -- 

above the Cretaceous bedrock. The aquifer is composed of an upper part, 

which is primarily Quaternary materials, and a lower part, which is 

primarily the Ogallala Formation of Tertiary age, from eastern Hall 

County westward and fine-grained Quaternary materials from eastern Hall 

County eastward. For this study, the aquifer is divided into two parts 

because the materials have significantly different hydrogeologic properties, 

The Quaternary materials generally have higher hydraulic conductivities 

and storage capacities than the Ogallala Formation or the fine-grained 

Quaternary materials in the eastern part of the study area.

Boundaries of the Aquifer

The boundaries of the aquifer are important in delineating the 

occurrence of ground water in the study area. Water levels and changes 

in water levels over time define the upper surface of the aquifer; 

whereas, the configuration and elevation of the bases of two aquifer 

parts define the lower surfaces of the aquifer. The saturated thickness 

of the aquifer and the depths to water provide additional information on 

the boundaries of the aquifer.

Water Levels

The water table, which constitutes the upper boundary of the aquifer, 

fluctuates in response both to short-term and long-term variations, 

mainly in recharge but also in discharge. By comparing maps showing the 

configuration and elevation of the water table before and after largescale irrigation development, it is possible to determine the effects of 

the development on the water table and to project probable future effects.

32
Figure 8 shows the configuration and elevation of the water table 

in the study area prior to the extensive ground-water development that 

began in the mid 1950's. The configuration shown for most of the Platte 

Valley was prepared from water-level data obtained during the summers of 

1931 and 1932 by Lugn and Wenzel (1938). The configuration shown for 

the uplands, however, was developed from all water-level data available 

through 1978. These data were used because almost no water-level data 

were available for the uplands prior to the 1960's. No irrigation wells 

existed in the uplands in 1931 (fig. 9) and few existed prior to the 

1950's. Most of the development of ground-water irrigation in the 

uplands followed the introduction in the late 1960 ! s of center-pivot 

systems. Thus, the water-level data obtained are assumed to represent 

predevelopment water levels.

Although the water-table contours on figure 8 represent water-level 

conditions in the Platte Valley prior to large-scale ground-water development, 

surface-water development beginning in the 1890 ! s had an impact on water 

levels in these counties prior to the 1930 ! s. Lugn and Wenzel (1938) 

report that by 1931 irrigation with surface water had already caused 

water levels to rise, especially under terrace lands. Also, by 1931 

about 600 irrigation wells were in operation in the Platte Valley from 

mid-Buffalo County through Hall County. As of 1931, there were no 

measurable water-level declines attributable to pumpage of ground water 

from these wells. Evidently, pumpage by these wells was offset by the 

interception of ground water that might otherwise have been lost to 

evapotranspiration.

Since 1931, the increase in the number of irrigation wells in the 

Platte Valley has been extraordinary. Figure 10 shows the distribution 

of irrigation wells registered with the Nebraska Department of Water 

Resources through December 31, 1976. Where well density is still low, 

water levels today probably do not differ greatly from those of predevelopment days. However, in many places, well density is so great that water 

levels today are bound to differ significantly from those predating 

development.

A second map showing configuration and elevation of the water table 

was required so that the ground-water flow model could be calibrated. 

The map prepared (fig. 11) is for the fall of 1976. Additional measurements 

of water levels were made to supplement those made in the fall of 1976 

in the uplands of Buffalo County (fall 1977) and Custer County (spring 

1978), and in southeastern Howard County (spring 1978).

Figure 11.--Configuration and elevation of the water table, fall of 1976, 

prepared from measured water levels.

37
An examination of the water-level configuration maps of 1931 (fig. 8) 

and 1976 (fig. 11) shows both similarities and differences. Groundwater flow directions, which are perpendicular to water-table contour 

lines in an isotropic aquifer, are similar for most of the area. Major 

differences in the directions of ground-water flow are evident in southeastern Howard County. There are also a few minor changes in the direction 

of ground-water flow along some reaches of the Platte River, where 

formerly gaining segments of the stream are now losing segments. Inadequacies 

in the predevelopment water-level map may account for the differences in 

southeastern Howard County.

Differences between figures 8 and 11 indicate that noticeable 

changes occurred in the relationship between stream and aquifer along 

the Wood River. Locations of gaining and losing segments of the stream 

changed significantly from 1931 to 1976. Also, although not evident on 

the figures, in 1931, the Wood River was live or flowing about 3 miles 

further upstream than in 1976. Also, water levels declined noticeably 

since 1931. The most significant decline occurred in the Platte River 

valley of Dawson, Buffalo, and western Hall Counties. Water-level 

declines in the valley are illustrated by the upgradient positions of 

the 1976 water-level contour lines with respect to their positions in 

1931.

Depth to Water

Depth to water is delineated on figure 12; depths in excess of 100 

feet are not differentiated further. First, land-surface elevations 

were obtained for the center of each grid node using Geological Survey 

7 i2-minute quadrangle topographic maps. These maps have a scale of 

1:24,000 and contour intervals of 10 feet. Then, depth to water for 

each node was computed by subtracting the 1931 water level (fig. 8) from 

the land-surface elevation at the node.

An examination of figure 12 together with figure 2 (topographic 

types) indicates that shallow depths to water occur in the flood plains 

and terraces. Substantial increases in the elevation of water levels 

may occur shortly after major recharge events in the fall and spring of 

each year. The areas where the depth to water is 5 feet or less probably 

are more extensive following such events than is indicated on figure 12, 

especially during the spring. Likewise, in some areas where depths to 

water are shown to be between 6 and 10 feet below land surface, water 

levels may occasionally rise to within 5 feet of the land surface.

Base of the Aquifer

As previously mentioned, the aquifer is divided into an upper and 

lower part, and the bases of the two parts are delineated on plate la 

and Ib, respectively. The base of the upper part slopes toward the 

east, with a decrease in elevation of about 1,400 feet -- from about 

2,700 to 1,300 feet. The base of the lower part of the aquifer also 

slopes toward the east, but with a decrease in elevation of only about 

950 feet. Elevations of this part vary from 2,250 feet in the west to 

1,300 feet in the east.

Saturated Thickness

Plate Ic and Id shows the variations in aquifer thickness with 

location of the upper and lower parts of the aquifer, respectively. The 

saturated thickness of the upper part ranges from zero feet in northern 

Buffalo County to 250 feet along the South Loup River in Custer County. 

The saturated thickness of the lower part of the aquifer ranges from 

less than 25 feet in the eastern part of the study area to more than 500 

feet in the western part.

The areas of zero saturated thickness for the upper part of the 

aquifer in 1931, primarily in Buffalo County, occurred naturally and 

were not due to dewatering of the aquifer. At that time, no irrigation 

wells had yet been developed in the upper part of the aquifer; all 

subsequent development has been in the lower part.

Hydraulic Characteristics

The hydraulic characteristics of the aquifer indicate the availability 

and volume of ground water. For this study, hydraulic conductivity and 

specific yield are the parameters necessary to define the hydraulic 

properties of the aquifer.

Hydraulic Conductivity

The distribution of hydraulic conductivity, K, of the upper and 

lower parts of the aquifer is shown in plate le and If, respectively. 

Hydraulic conductivity of the upper part ranges from 1 to 300 feet per 

day, and that of the lower part from 1 to 79 feet per day. On plate 

le, a hydraulic conductivity of zero feet per day is indicated where the 

upper part of the aquifer was unsaturated. On plate If, however, a 

hydraulic conductivity of zero feet per day is indicated where the lower 

part of the aquifer is not present.

40
The hydraulic-conductivity maps were prepared starting with 

lithologic logs of test holes. For each lithologic unit described in 

the test-hole logs, a hydraulic-conductivity value was assigned according 

to the grain size of material comprising the unit and its degree of 

sorting and (or) silt content using table B given in "Additional Information." Each value, so assigned, was then multiplied by the thickness 

of the lithologic unit it represented. The sum of the products was 

divided by the saturated thickness of all the lithologic units to yield 

a weighted-average hydraulic conductivity for each of the two parts of 

the aquifer at each test-hole site. The weighted-average values were 

then plotted, and maps were developed showing lines of equal hydraulic 

conductivity. It is from these maps that the ranges in hydraulic conductivity shown for individual nodes in plate le and If eventually 

were obtained.

Hydraulic-conductivity values determined from aquifer tests (Lugn 

and Wenzel, 1938) and those derived from specific-capacity data for 

irrigation-wells were used to check and, in a few cases, modify the 

weighted-average values obtained as described in the previous paragraph. 

Aquifer-test data pertained only to the upper part of the aquifer; 

whereas, specific-capacity data pertained to the entire aquifer.

During the modeling process, the need for some modifications in the 

assigned weighted-average hydraulic-conductivity values became apparent. 

The modified values have been incorporated into plate le and If.

Hydraulic conductivity shown in plate le and If, if multiplied by 

the appropriate saturated thickness from plate le and Id, can be used 

to compute tne transmissivity of the aquifer at each node. The transmissivity is a good indicator of potential well yield at a given location. 

Areas where transmissivity is large are favorable for developing wells 

having high yields.

Specific Yield

The specific yield, Sy, or drainable porosity of the upper and 

lower parts of the aquifer is indicated in plate Ig and Ih, respectively. 

The range in Sy for the upper part of the aquifer is 0.16 to 0.26, and 

that for the lower part is 0.12 to 0.21.

Specific-yield values were developed, as were the hydraulic-conductivity 

values, from lithologic logs of test holes. For each lithologic unit, a 

specific-yield value was assigned depending on grain-size class or 

range, using table B given in "Additional Information." A weightedaverage Sy for the saturated materials at each test hole was computed in 

the same manner described earlier for hydraulic conductivity. Values 

for individual test-hole sites were plotted, maps with lines of equal

41
specific yield were prepared, and the specific-yield values shown on 

plate Ig and Ih for individual nodes were selected. The need for some 

changes in the original Sy values selected became evident during the 

modeling procedure; these changes have been incorporated into the illus 

trations.

Flow in the Aquifer

Ground water flows in the direction of decreasing hydraulic head, 

or approximately normal to the water-table contours (figs. 8 and 11). 

Tne regional ground-water flow pattern is modified near discharge and 

recharge areas. The flow paths converge toward areas of discharge and 

diverge from areas of recharge.

The velocity of ground-water movement through an aquifer is a 

function of the hydraulic conductivity and the gradient of hydraulic 

head, which is the potential energy of the water. The velocities are 

usually low and they are expressed as follows (Lappala, 1978) :

where

q. = the average unit area rate of volume flux, LT ,

K = Hydraulic conductivity, LT ,

h = total hydraulic head, L,

x. i = a coordinate direction, ' L. 

Rates of ground-water movement in the study area range from less than 10 

feet per year to slightly more than 100 feet per year.

Underflow of ground water into the study area is along the western 

border of Dawson and Custer Counties and can be calculated as follows 

(Lappala, 1978) :

b. = average aquifer thickness over interval i, L,

. = width of the increment i, L, iw

( ) = hydraulic gradient normal to the boundary, dimensionless. 9n .

i

The underflow into the study area was determined by the above 

equation to be 28,700 acre- feet in 1931 and 39,600 acre- feet in 1976.

The average volume of water in storage in the summers of 1931 and 

1932 within the two parts of the aquifer were calculated by multiplying 

average saturated thickness by specific yield. The volume in storage in 

the upper part of the aquifer was 58,300,000 acre- feet, and that in the 

lower part was 62,500,000 acre- feet.

Outflows from the aquifer consist of discharge from domestic, 

municipal, industrial, and irrigation wells, ET losses from shallow 

water-table areas, and ground-water discharge to the surface-water 

system. ET losses and ground-water discharge to streams are handled 

within the ground-water flow model. The net recharge or discharge, 

which is entered into the flow model, will be discussed in the RechargeCIR section. Underflow of ground water to areas outside the study area 

is negligible, and for modeling purposes, is assumed to be intercepted 

by the surface-water system.

43
PROCEDURES FOR ESTIMATING RECHARGE-CIR DATA

Hydrologic data seldom are in a form directly usable in a groundwater flow model. Ordinarily, "raw" data must be converted, combined 

with other data, or operated upon in some other manner before it can 

become usable. This section provides information on the procedures 

adopted to prepare data for use in the model and on simplifying assumptions made with regard to the data.

Soil-Zone Programs

The movement of water through and within the soil zone is represented 

by two computer programs: one is called the potential-evapotranspiration 

program (PET), and the other is called the soil-water program. These 

programs require input of climatic, soil, and crop data to calculate the 

CIR of the crops and the amount of water that will pass through the soil 

zone to become recharge to the aquifer.

The physical basis for, and operational procedures of the soil-zone 

programs were discussed by Lappala (1978). No changes were made in the 

PET program for this study, but two major changes were made in the soilwater program. The first change was the addition of a method to handle 

the nonuniform distribution of rainfall with respect to time. This 

involved adding a regression equation to the soil-water program (Fred J. 

Otradovsky, U.S. Bureau of Reclamation, written commun., 1979) in an 

attempt to account for the temporal errors that result from using 

monthly instead of daily precipitation data. The results of this change 

were increases in the values used for precipitation and deep percolation 

or recharge.

The second change in the soil-water program was the addition of a 

method to account for recharge that results because of seepage from road 

ditches, ponds, low areas, and intermittent drains. Originally, the 

rainfall-runoff curves in the soil-water program were developed from 

data collected on 4-acre watersheds and reflected only initial surface 

runoff. However, when larger areas are considered, much of the original 

surface runoff reaches road ditches, ponds, swales, etc., from which 

water percolates downward to become recharge to the aquifer. The 

fraction of the original surface runoff that is subsequently retained 

and percolates downward to become recharge is referred to as "seep" and 

is treated as additional deep percolation in the soil-water program 

(Fred J. Otradovsky, U.S. Bureau of Reclamation, written commun., 1979).

44
The PET program computes the monthly PET for the 15 weather stations 

in the study area. Inputs to the program are: (1) Monthly values for 

precipitation, air temperature, and percent possible sunshine; (2) the 

mean minimum and maximum air temperatures for the warmest month of the 

year (July); and (3) the mean daily solar radiation values on cloudless 

days for each month.

The locations of the weather stations are shown on figure 3. The 

areas for which records from a given station are assumed to apply are 

shown on the figure by Thiessen polygons. The station locations and 

polygons are shown on figure 3 because of the close relationship in the 

modeling process between climatic data and the soil properties.

Precipitation data were available for each weather station; however, 

air temperature data were not, and those for the Gothenburg, Kearney, 

and Central City stations were assigned to the other weather stations 

according to their location. If air temperature and precipitation data 

were missing, they were estimated by linear regression with data from 

nearby stations. Data on percent possible sunshine and mean daily solar 

radiation on cloudless days were available only for the National Weather 

Service station at North Platte, about 35 miles west of this study area.

Monthly output from the PET program and mean monthly precipitation 

and air temperature for each weather station were used as input to the 

soil-water program. Additional inputs to this program are: (1) Crop 

coefficients (fig. 13), which are the monthly ratios of actual to PET 

for row crops, alfalfa, small grain, and pasture and range; (2) infiltrationcurve coefficients coupled with infiltration-curve numbers (fig. 14) 

that are dependent on the soils, lithology, topography, and crop cypes; 

and (3) water-holding capacity of the soil.

Figure 13 shows crop coefficients for different times of the year. 

These coefficients were modified from Lappala (1978). Modifications are 

the use of a coefficient of 1.0 for row crops during July, and a lowering 

of the coefficient for pasture and range from July through October when 

the grasses are dormant.

Figure 14 shows the relationship between monthly precipitation and 

monthly infiltration. The relationship differs markedly for different 

combinations of soil, vegetation, and topography, and therefore is 

expressed using four different curves. Selecting the appropriate curve 

is simple. For example, for sandy soils on flat topography, monthly 

infiltration is determined using curve 1. Table 6 gives the available 

water capacity, curve number, and seep values used for the nine soil 

groups in the study area.

Output from the soil-water program includes data on the following 

items for each soil, crop, and weather station: (1) Infiltration, (2) 

ET, (3) surface runoff, (4) irrigated land deep percolation, (5) CIR, 

(6) irrigated land soil moisture, (7) dryland deep percolation, (8) 

dryland water shortage, and (9) dryland soil moisture. Deep percolation 

from dryland areas entirely from precipitation and seepage from ditches, 

drains, and swales; whereas, deep percolation from irrigation areas is 

from precipitation, excess irrigation, and seepage from ditches, drains, 

and swales. Output from the soil-water program for the soils that are 

found in the area enclosed by the Thiessen polygons, identified with the 

Gothenburg, Kearney, and Central City weather stations, is given in 

table C of "Additional Information." Ninety-two different combinations 

of weather stations and soils exist in the study area; table C presents 

a representative subset of these data.

Recharge-Discharge Programs

Computation of recharge to the ground-water system and of discharge 

from it requires data for a variety of parameters. Unfortunately, very 

few of these parameters are measurable directly; thus, procedures, were 

developed by which their magnitudes could be estimated. These procedures 

comprise tne recharge-discharge programs.

For this study the recharge-discharge programs consist of computer 

programs and the ET subroutine in the ground-water flow model. The 

Pumpage and Flowx programs, developed by the authors, compute the rechargedischarge values and streamflow data needed as input to the ground-water 

flow model. The Pumpage program uses recharge-CIR data from the soilwater program, together with data on additional parameters, to compute 

net recharge to the aquifer or discharge from the aquifer at each node 

for each pumping period. The Flowx program computes either the inflow 

to or the outflow from stream nodes using data from nodes just outside 

the study area but adjacent to the stream nodes. The ET subroutine by 

Trescott and others (1976) computes the discharges from shallow groundwater nodes for each time step within each pumping period.

Assumptions in the Procedures

Numerous assumptions are incorporated in the recharge-discharge 

program. Those believed to be most significant are discussed in the 

following paragraphs.

The first group of assumptions pertain to development of the Pumpage 

program. No measurements were available on the volumes of surface water 

diverted by canals that reach irrigated fields. After discussions with 

cooperators and personnel of the U.S. Bureau of Reclamation, the assumption

49
was made that only 50 percent of the surface water diverted actually is 

applied in irrigation; the other 50 percent is assumed to be seepage 

loss that recharges the aquifer (Fred J. Otradovsky, U.S. Bureau of 

Reclamation, personal commun., 1979). Another assumption pertaining to 

surface water is that the acres irrigated with surface water have remained 

unchanged since 1970, both in location and extent.

The assumption that only 50 percent of the surface water diverted 

is actually applied in irrigation leads to still other assumptions. If 

the 50 percent applied is more than the CIR for a given node, the residual 

water is assumed to become recharge to the aquifer. If, on the other 

hand, the 50 percent applied is less than the CIR for the node, the 

deficit is assumed to be made up by pumping of ground water if an irrigation well exists in the node.

Data available on acreages of alfalfa do not distinguish between 

irrigated and nonirrigated acres. After discussions with cooperators, 

20 percent of the alfalfa lands in the Platte River valley from Gothenburg to west of Kearney is assumed to be irrigated with ground water 

each year, and the remaining 80 percent is assumed to be subirrigated 

witn shallow ground water.

The acres irrigated with ground water in each study are computed as 

the number of irrigation wells per node multiplied by the acres irrigated 

per well. The number of wells per node for each year was computed from 

the file of registered irrigation wells of the Nebraska Department of 

Water Resources, and the acres irrigated per well were computed for each 

county for 5-year intervals from data on registered irrigation wells 

given in "Nebraska Agricultural Statistics" (Nebraska Department of 

Agriculture, annual reports). The number of registered irrigation wells 

and acres irrigated per well for each county for 5-year intervals are 

given in table 7.

Procedures used to determine the acres irrigated with ground water 

have been substantiated by comparing computed results with results of 

field data collected by the Bureau of Reclamation for Buffalo, Hall, and 

Merrick Counties during 1946, 1970, and 1971. Results of this comparison 

are given in table 8. The greater number of wells and the lesser acres 

per well computed for this study from the Agricultural Statistics probably 

can be attributed to the inclusion of all registered irrigation wells 

drilled through the end of each year, even though not all such wells 

were used during the year.

Withdrawals of ground water for domestic, stock, industrial, and 

most municipal purposes are assumed to be insignificant with respect to 

regional water-level changes. Thus, ground-water usages for these 

purposes, except that for the cities of Grand Island and Kearney (table 9),

Does not include pumpage from the Platte River well 

field, which was first used in 1965.

were not included in the recharge-discharge model. Of the withdrawals 

for Grand Island, only those from the well field within the city were 

included; those from the well field along the Platte River that fall within 

a stream node were not included because stream nodes are modeled as 

constant-head nodes.

To determine the volume of ground water pumped, the number of 

irrigated acres is multiplied by the CIR for a particular land use. An 

assumption is made that sufficient irrigation water will be applied to 

satisfy the CIR for that particular use. Thus, land use is the only 

unknown factor in this procedure for determining the pumpage.

Although information is available to indicate acres for each landuse category -- row crop, alfalfa, small grain, pasture and range --by 

counties each year, comparable information on a farm-by-farm basis is 

not available. Therefore, assignment of acreages to different land-use 

categories for individual nodes for different periods clearly is impossible. 

The Conservation and Survey Division of the University of Nebraska 

developed land-use data for 1974 for the Central Platte Natural Resources 

District, and the U.S. Soil Conservation Service developed, but did not 

publish, a 1977 land-use map that covers the entire study area. Using 

information from these sources, acreages were assigned to each of the 

four land-use categories for each node. The acreages so assigned were 

not allowed to vary.

53
Additional lands brought under irrigation are assumed to have been 

used for growing dryland row crops and small grains. It is also assumed 

that all additional irrigated lands are irrigated row crops. Thus, as 

irrigated row-crop acreages increase, dryland row-crop and small-grain 

acreages decrease.

Calculations in the Flowx program also involve some assumptions. 

This program is used to quantify the movement of water between boundary 

streams and the aquifer immediately outside the study area.

The rate of water movement, in cubic feet per second, was calculated 

by using the summers of 1931 and 1932 water levels (fig. 8), the hydraulic 

conductivity for the entire aquifer at each node, the saturated thickness 

for the entire aquifer at each node, and the area of each node. The 

rate of water movement equals the product of the following: (1) hydraulic 

conductivity, (2) saturated thickness, (3) differences in hydraulic head 

between the stream node and the adjacent node outside the study area, 

and (4) the area of the node.

The output from the Flowx program -- the rate of water movement -- 

was input into the ground-water flow model and held constant for the 

entire calibration and predictive time intervals. An assumption was 

made that hydraulic-head changes from 1931-32 to 1976 did not significantly affect the rate of water movement. The rate of water movement 

was from +7.14 to -3.28 cubic feet per second, where positive values 

represent flow into streams from the ground-water system and negative 

values represent flow out of streams into the ground-water system.

The procedures that are used for computing evapotranspiration from 

the aquifer are based, in part, on assumptions. The physical processes 

that control ET losses from ground water are difficult to represent in a 

mathematical equation. For this study, the ET losses from ground water 

are assumed to be represented by the linear relationship,

X- M = ETr ETT CGi,j -Vj,^ (3)

f i i k)

The terms in this equation, modified from Trescott and others (1976), 

are as follows:

q is the ET from ground water for node (i,j) and time (k),

C L. f - . -I -v

IT ~l K I >J> in inches per year;

ETr is the maximum evapotranspiration rate from ground water, in 

inches per year;

54
ETz is the depth below the land surface at which ET ceases, in feet;

G. .is the elevation of the land surface, in feet; and i>J

h. is the elevation of the water table, in feet. i,J,k

Use of the terms ETr and ETz is based on assumptions that the ET rate 

decreases linearly with depth, and that ET ceases at one depth regardless 

of type of soil or crop.

The ET values calculated by equation (3) represent ET losses or 

discharges from the aquifer. ETr and ETz were selected as 9 inches per 

year and 5 feet, respectively, after extensive experimentation with the 

values utilizing steady-state conditions in the ground-water flow model. 

When water levels at any node drop below ETz (5 feet), the ET losses are 

zero at that node.

ET salvage occurs when the water table is lowered by ground-water 

pumpage. The amount of ET salvaged equals the amount represented by the 

reduction in the water table down to ETz, which for this study is 5 

feet. If the water table is maintained at a lowered level, ET salvage 

resulting from the original lowering of the water table becomes a continuing process. For this study, ET salvage is approximated as a linear 

function. It is zero when the water table is from 0 to 1 foot below 

land surface and increases linearly with depth to a maximum of 9 inches 

(ETr) at 5 feet below land surface. At depths to water greater than 5 

feet, ET salvage remains at its maximum.

Input and Output

The input data differ for the various components of the rechargedischarge programs. Input data for the Pumpage program are as follows: 

Canal diversions (table 3); municipal ground-water pumpage for Grand 

Island and Kearney (table 9); number of wells per node; output from the 

soil-water program (table C of "Additional Information); land-use data; 

and acres irrigated per well (table 8). This program is run once for 

each pumping period and the output data are the net recharge or discharge 

for each node, which in turn become input data to the ground-water flow 

model.

The Flowx program uses as input water levels of the summers of 1931 

and 1932, the average hydraulic conductivity, and the average saturated 

thickness of the aquifer. This program is run once for the entire 

simulation, and the output data, which are the flux values for the 

stream nodes, are read into the ground-water flow model for each pumping 

period.

55
The ET-loss procedures are performed within the model for each time 

step within the pumping period. Input data are the water levels, which 

may change after each time step; the land surface elevation; ETr; and 

ETz. Output data are ET flux values, which are handled as discharge 

from the aquifer.

The annual streamflows and canal diversions are computed and read 

into the ground-water flow model for each pumping period.

SIMULATION OF THE GROUND-WATER SYSTEM

The development of the ground-water flow model includes the selection 

of a type of model that can adequately represent the ground-water system, 

the generation of the necessary hydrogeologic and recharge-CIR data, and 

the calibration of the model and data against known changes in the water 

levels.

Description of the Ground-Water Flow Model

The type of model used in this study to simulate both the groundwater system and streamflow is the U.S. Geological Survey's two-dimensional, 

finite-difference model of ground-water flow developed by Trescott and 

others (1976). For this study, four modifications were made in the 

model. First, the model was modified to handle relationships between 

ground water and streamflow where streams are connected to the aquifer. 

Streamflow was handled by considering the stream network to be represented 

by a binary-tree structure. Surface water discharging into or from 

streams is processed by this accounting procedure. In addition, surface 

water that flows from the stream into the aquifer (inflow) or ground 

water that flows from the aquifer into the stream (outflow) are handled 

by this accounting procedure (Lappala, 1979). Second, it was modified 

by the addition of constant-gradient boundary nodes where water is added 

or removed from such nodes to maintain a constant water-table gradient 

(Lappala, 1979). Third, the procedures for storing hydrogeologic parameters 

were modified by Eric G. Lappala and Joe S. Downey (written correspondence, 

1978) so that data for only the active nodes in the model are stored 

within the computer's central processing unit. Finally, the model was 

modified to permit the use of two values each for hydraulic conductivity, 

specific yield, and top and base of the aquifer for each node. This 

final modification, developed by Eric G. Lappala (written correspondence, 

1978), allowed the use of hydrogeologic parameters required to describe 

both the upper and lower parts of the aquifer. This final modification 

was tested during this study by running the model as both one- and twolayer cases with the maximum possible pumpage; that is, with 100 percent 

of the study area irrigated with ground water. No stability or numerical 

problems occurred, indicating that the model was functioning properly 

with this modification.

56
The north, south, and east boundaries of this study area are streams 

(fig. 4). Nodes in which the streams are present are treated as constanthead nodes -- nodes in which water levels are not permitted to vary 

unless the streamflow in the node is zero. The west boundary lies 

approximately 3 miles west of the Central Platte NRD's boundary. Nodes 

along this boundary are constant-gradient nodes, in which gradient 

across them remains constant throughout time, but changes in saturated 

thickness of the aquifer are permitted. The extension of the study to 

the west was required to eliminate potential water-level problems at the 

NRD's boundary caused by the use of the constant-gradient nodes.

Assumptions in the Ground-Water Flow Model

Some assumptions necessary in developing and running the groundwater flow model pertain to the required input data; whereas, others 

pertain to the development and operation of the model. Assumptions 

pertaining to input data have already been discussed. Discussions that 

follow pertain to assumptions in the development and operation of the 

model.

1. The entire ground-water system can be represented as a nonhomogeneous, isotropic, unconfined aquifer. There may be small areas in 

which tiie ground-water system responds like a confined aquifer; however, 

the regional response is that of an unconfined aquifer.

2. The vertical ground-water flow component is negligible; thus, 

ground-water flow is assumed to occur only in the horizontal plane.

3. Irrigation wells penetrate, and are open to, the entire thickness 

of the upper and lower portions of the aquifer.

4. Pumping rates of irrigation wells are not affected by the 

saturated thickness of the aquifer. Thus, in model operation, the 

pumping rates are not adjusted as the aquifer is dewatered until the 

aquifer is completely dewatered and pumping ceases.

5. Underflow does not exist in nodes where the streams are connected 

to the aquifer.

6. The boundary conditions -- constant-head nodes and constantgradient nodes -- represent the aquifer at their locations.

57
Calibration of the Ground-Water Flow Model

Calibration of a model is the process of adjusting model input so 

that model output will be both realistic and valid. Commonly, calibration 

is accomplisned by trial-and-error adjustment of input data until 

differences between model-output data and measured data are within 

acceptable limits. The calibration of the model usually involves operating the model under steady-state and transient conditions. Steady-state 

conditions are those in which the model results are independent of time 

and in which the elements of the hydrogeologic system are assumed to be 

in balance. Transient conditions are those in which the model results 

are dependent upon time and in which the elements of the hydrogeologic 

system are not required to be in balance.

For this study, the ground-water flow model was calibrated using 

the steady-state procedures to check the validity of data for hydraulic 

conductivity, recharge, water levels, and ET losses from ground water, 

and to determine the sensitivity of model results to changes in the 

various input data. Also, the model was calibrated using transient 

procedures occurring between 1931 and 1976. Model input values were 

adjusted until a reasonable fit occurred between the computed and measured 

1976 water levels.

Steady-State Procedures

In operating the model using steady-state procedures, water levels 

from the summers of 1931 and 1932 (fig. 8) were used as the initial 

water levels, together with the weighted-average hydraulic conductivity 

and the elevations of the top and base of each part of the aquifer. 

With steady-state procedures, no storage of water is allowed in the 

model; thus, the specific-yield values were set at zero. Also, with 

steady-state conditions, model results are independent of time; therefore, the model was run for only one time step.

The ground-water model was run using steady-state procedures to 

check and, if necessary, to adjust some of the input data. Results from 

different runs in which selected input data were varied were compared; 

adjustments were then made in the original input data so as to produce 

model results that successfully simulated more closely the true response 

of the ground-water system.

The recharge data were modified, as necessary, by adjusting the 

soil, climate, crop, and seep values. For a few soils, the available 

water capacity (table 6) was adjusted to provide either more or less 

recharge. These adjustments were within a plausible range of available 

water capacities for the individual soils that comprise the soil group.

58
Due to the spatial variability of the climatic data, some adjustments 

were necessary so as either to raise or lower recharge. However, most 

were to lower recharge by 20-25 percent.

The only adjustment made in the crop data was to lower the coefficient 

(fig. 21) for pasture and range, because grasses become dormant during 

the summer. The effect was to lower the dryland and irrigated water 

requirements for pasture and range.

Adjustments in seep values (table 6) were made using information 

provided by Fred J. Otradovsky, U.S. Bureau of Reclamation (personal 

commun., 1979), who has developed procedures for testing input parameters 

to the soil-water program. These adjustments were made so that the seep 

values represented more accurately the seepage losses of the different 

soil groups. The effect of these changes were to increase recharge in 

some places, and to decrease it in others.

Steady-state procedures also were used to adjust the hydraulic 

conductivity for some of the nodes and the ET rate. The model was run 

using hydraulic conductivities ranging from 0.4 to 2.0 times the initial 

conductivities for both parts of the aquifer. The hydraulic conductivities 

selected were those that yielded water levels that most nearly matched 

those of the summers of 1931 and 1932. The average change in hydraulic 

conductivities was approximately 1.3 times the initial values. Similar 

techniques were used in selecting an ET rate; in this case, the model 

was run using ET rates ranging from 6 to 12 inches.

A major assumption in the procedures for adjusting input data so 

that computed and measured water levels were in agreement was that the 

summer 1931 and 1932 water levels were the most accurate input data. 

These water levels, therefore, were the last data to be adjusted. Water 

levels in the upland areas, which were not developed from the summer 

1931 and 1932 measurements, were adjusted a number of times.

Transient Procedures

In running the model using the transient procedures, the water 

levels for the summers of 1931 and 1932 (fig. 8) were used as the initial 

water levels. The model was then run for the period January 1931 to 

September 1976 with the adjusted hydraulic conductivity, specific yield, 

elevations of the top and base of each part of the aquifer, and with 

other adjusted input data.

Normally, the initial water levels used in the model would have 

been smoothed by running the steady-state procedures to eliminate waterlevel irregularities that are caused by inadequacies in measurement, 

contouring, and coding. This was not done, however, because complete

59
precipitation records for 1895 to 1931 are available for only 3 of the 

15 weather stations in the study area. Therefore, recharge-discharge 

data necessary for generating the 1931-32 water levels are incomplete, 

and additional errors in the water levels would have occurred because of 

the inadequate climatic data. Thus steady-state procedures were used 

only to check and adjust some of the input values.

Output from the Flowx program, streamflows, and discharge from the 

Pumpage program were not modified while running the transient procedures. 

However, values for recharge (deep percolation) for parts of southwestern 

Custer County and southeastern Howard County were decreased by about 50 

percent during the running of the transient procedures. Excessive 

simulated water-level rises were indicated for these areas when running 

the model for the calibration period of January 1931 to September 1976. 

Fine-grained materials beneath the surficial Valentine soils (fig. 3), 

which could not be directly included in the soil-water program, prevented 

complete deep percolation of water to the aquifer.

Hydraulic conductivity and specific-yield values were changed for 

a few nodes during running of the transient procedures. Plate le, If, 

lg, and lh indicate the final values used for these parameters.

Calibration of the ground-water model was considered complete when 

the computed 1976 water levels compared favorably with the measured 1976 

water levels. Comparison of lines of equal water-level elevation prepared 

using computed water levels (fig. 15 with those measured water levels 

(fig. 11) shows good agreement, especially from Hall County eastward. 

West of Hall County the contour lines on the two figures are similar but 

show some divergence. The lines prepared from the computed water levels 

are more generalized and do not reflect the local effects of pumping and 

recharge as well as do the lines prepared from measured water levels.

Differences between computed water levels (fig. 15 and those 

derived from measurements in 1976 (fig. 11) are shown for each node on 

figure 16. For most nodes, the differences are less than 10 feet. 

Nodes for which differences are more than 10 feet are mostly in uplands 

where depths to water exceed 100 feet and where measured water-level 

data are sparse. The accuracy of water levels for individual nodes 

derived from measurements is plus or minus 5 feet, or one-half the 

contour interval of 10 feet used on work maps from which figure 11 was 

prepared.

A root-mean-square (RMS) analysis was performed on the 1976 computed 

and measured water levels as a check on the calibration of the model. 

This analysis involved the following: (1) Subtracting the computed from 

the measured 1976 water levels for each node, (2) squaring the differences,

(3) adding all the squared differences for all the nodes, and (4) dividing 

this sum by the number of nodes and taking the square root of the result. 

The results of the RMS analysis, excluding the constant-head nodes, for 

all flood plain, terrace, and upland nodes, for flood plain and terrace 

nodes, and for upland nodes were 8.84, .7-76, and 9.66 feet, respectively. 

The lower RMS values (7.76) occur in the flood plain and terrace areas 

where both the 1931-32 and 1976 water-level data are more plentiful. 

Such RMS values, which are less than a water-level contour interval of 

10 feet, indicate that water levels generated by the model are acceptable 

for this study.

Model-computed streamflows are compared to measured streamflows -- 

those computed from measurements and gaging records --in table 10, The 

model-computed flows were generated using data on precipitation and on 

surface water (averaged for the nonirrigation pumping period of September 

through May) flowing into the study area. The model-computed flows 

represent streamflow for May 31; whereas, the measured flows are mean 

daily flows for the month of May.

It is unrealistic to expect that the computed flows for May 31 

would match individual daily flows published for May 31. This is because 

individual daily flows are dependent upon the time relationship between 

precipitation, surface runoff, and surface-water discharges, and thus 

are highly variable. However, one might expect them to match the mean 

daily flows for May in which the time component is not as critical. 

This they do reasonably well.

Model-computed and measured streamflows for the irrigation pumping 

period of June through August compare less favorably than do the flows 

for the nonirrigation pumping period. This is due principally to the 

extreme variability in measured streamflows during this period, which is 

caused by variable precipitation and snowmelt along the upper reaches of 

the Platte River.

A check of the computational performance of the model was made by 

examining the balance of fluxes (flows) into and out of the aquifer. 

Table 11 indicates the rates of the different types of flux that were 

generated by the model for the irrigation pumping periods during 1931, 

1950, 1960, 1970, and 1976. The sums of the rates in the last column 

are all extremely small, indicating that the model was not encountering 

stability or other numerical problems and that the model was properly 

processing and tabulating flux values. The negative storage values 

(ground water added to storage) and the large recharge values for 1950 

and 1960 represent time periods during which precipitation was much 

higher than average.

Sensitivity Analysis

The effects of data uncertainties on simulation results can be 

assessed, to a certain degree, by performing sensitivity analyses on the 

various types of input data for both steady-state and transient conditions. 

The sensitivity of the model was examined by adjusting hydraulic conductivity, specific yield, and recharge within their expected ranges and 

observing the resulting changes in computed water levels.

Results of sensitivity analyses indicated that water levels were 

more responsive to adjustments in recharge than to adjustments in hydraulic 

conductivity or in specific yield by a factor of at least 2. Also, the 

magnitude of changes in water levels in response to adjustments in 

discharge and in ET losses are similar to the magnitude of changes in 

response to adjustments in recharge.

Potential Uses and Limitations of the Calibrated Model

A variety of management alternatives or predictive schemes can be 

examined utilizing the calibrated model. However, careful construction 

and application of the predictive schemes must be followed or erroneous 

results will be produced. Also, there are limitations on what the model 

can predict with reasonable accuracy even if good techniques are employed.

The calibrated model can be used to examine effects on the hydrogeologic system of a variety of ground-water development rates, irrigationapplication rates, surface-water irrigation projects, and streamflow 

changes. Alternatives in ground-water development might include: no 

additional development, cutbacks in development, or additional development 

at different rates estimated by a variety of procedures.

Alternatives in rates of applying irrigation water might be based 

on existing technology, future technology, or expected changes in farm 

practices. An examination of literature on existing technology reveals 

that the irrigation-application rates vary significantly with type of 

cultivation, of weed-control programs, and of irrigation-scheduling 

procedures. Future technology may reduce rates at which irrigation 

water must be applied through development of more drought-resistant 

varieties of plants and through the use of more water-efficient farming 

practices. Changes in farming practices might include the growing of 

crops that require less water or deliberately using less irrigation 

water than is required to achieve maximum yield.

68
Numerous alternatives relating to surface-water use are possible 

for the study area. Present surface-water irrigated acreage in Dawson 

and Buffalo Counties might be altered so that more or less ground water 

for irrigation may be required. Irrigation projects using surface water 

have been proposed for Buffalo and Hall Counties that might provide 

recharge to the ground-water system and reduce ground-water pumping by 

converting some ground-water irrigated lands to surface-water irrigation.

Variations in the flows of the boundary streams are possible in the 

future because of additional diversions either within the study area or 

upstream, or because of additional ground-water irrigation in upstream 

areas, or both. The probable effects of these variations on the hydrology 

of the study area can be examined in the ground-water flow model by 

varying flows in the boundary streams.

The model should not be used to examine management alternatives 

that it was not designed to handle. For example, this model was not 

designed to handle relationships between streamflows and bank storage in 

the ground-water system during floods. Nor was it designed to handle 

alternatives relating to economics, government policies, and numerous 

other items.

MANAGEMENT ALTERNATIVES EXAMINED

Selecting management alternatives to be examined with a groundwater flow model is often difficult because water-resources development 

is uncertain. A technique commonly used is to identify a type of development likely to take place and to describe the effects on the hydrology 

of the area for both an assumed lowest and assumed highest probable rate 

of development. At least tentative management decisions can be made 

using results of interpolation between the effects of the assumed lowest 

and highest probable rates of development.

Also, the number of alternatives that can be examined is limited by 

practicable considerations of cost and time. It is important, therefore, 

that the alternatives selected for examination be realistic and meet the 

perceived needs of planning agencies. To assure this, the alternatives 

were selected in close consultation with personnel of both cooperating 

agencies.

The management alternatives examined pertain to three major areas 

of concern. These are as follows: (1) The effects on ground-water 

levels and on streamflows that might result from diverting annually 

within the study area an additional large volume of water from the 

Platte River; (2) the effects on water levels and on streamflow if no 

new ground-water irrigation development takes place from 1980 through

69
2020, but if five different irrigation-application rates are used; and 

(3) the effects on water levels and on streamflow if the annual rate of 

irrigation development of irrigable but unirrigated land is 2, 5, or 8 

percent and if the irrigation-application rates are less than, equal to, 

or greater than CIR.

Additional Diversion of Water from the Platte River

The first management alternative examined is the diversion of an 

additional 125,000 acre-feet of water per year from the Platte River. 

This alternative is based on a plan to divert as much as 125,000 acrefeet per year for a proposed irrigation project outside the Platte River 

Basin. Water for the proposed irrigation project would be diverted from 

the Central Nebraska Public Power and Irrigation District's Tri-County 

Canal. Without this diversion, this water would be returned to the 

Platte River at stream node 47,28 -- the Johnson Power Return on figures 4 

and 5. The maximum rate of diversion is set at 450 cubic feet per 

second, and at no time would it be allowed to exceed 75 percent of the 

flow of the Platte River. Diversions are to be permitted between September 1 

and January 15, with additional diversions permitted after April 1, if 

necessary to obtain 125,000 acre-feet. However, for modeling purposes, 

all diversions are made between September 1 and January 15.

The first step in analyzing this management alternative was to run 

the ground-water model using steady-state procedures. The 1976 waterlevel configuration map (fig. 11) was used as the initial water levels. 

The net recharge or discharge values used were the average values for 

the 1931 to 1976 climatic period with 1976 irrigation-well distribution 

and land use. Output from running the steady-state procedures were 

"smoothed" 1976 water levels. Irregularities in the measured 1976 water 

levels and errors and irregularities in hydraulic conductivity and 

recharge-discharge values were lessened by developing the "smoothed" 

water levels.

The final step was to run the ground-water flow model with transient 

procedures. In this step, the "smoothed" 1976 water levels were used as 

the initial water levels. The 1957 water-year streamflow and climatic 

data and the 1976 irrigation-well distribution and land-use data were 

used to generate net recharge or discharge values for each node for a 1- 

year period. This was repeated five times using the same data to generate 

5 years of data.

The rationale for the previous procedures is as follows: First, 

this alternative has been examined earlier using a ground-water flow 

model developed for the Platte River Basin, Nebraska Level B Study 

(Lappala and others, 1979). The purpose of this current examination is

70
to update the earlier results to 1976 ground-water conditions. Second, 

this current examination of the alternative was performed before the 

present ground-water flow model was completely calibrated. Therefore, 

steady-state procedures were used to develop the "smoothed" 1976 water 

levels used as input for the transient procedures instead of modelcomputed 1976 water levels. Third, 197-6 data on irrigation-well distribution 

and land use were used to generate recharge-discharge data because they 

correspond in time to the 1976 water levels. Fourth, climatic data for 

the 1931-76 period were used in order to include a wide variety of 

climatic conditions. Finally, streamflow values used for stations along 

the Platte River were those of the 1957 water year, because they are 

typical of those one might expect during a prolonged period of low flow. 

This is indicated by the fact that the 1957 annual flow at Grand Island 

was 483,000 acre-feet, which is close to the 479,000 acre-feet average 

for the 1953-57 period -- the period of lowest prolonged streamflow on 

record since closure of the dam on Lake McConaughy.

The output from two model runs using transient procedures are two 

sets of data, one indicating what the water levels would be with the 

diversion, and the other indicating what the water levels would be 

without the diversion. The differences between these sets of water 

levels for March 31, after 5 years of simulation are shown on figure 17 

It should be noted that the differences are those that developed following 

a prolonged 5-year period of low flow. They clearly would be less 

following shorter prolonged periods of low flow, or periods of normal or 

high flows. It should also be noted that a diversion of 125,000 acrefeet of water represents 26 percent of the annual flow at Grand Island 

for the 1957 water year. However, this diversion would represent only 

12 percent to less than 5 percent of the annual flow for normal- or 

high-flow years, respectively.

An evaluation of figure 17 indicates that the declines in water 

levels greater than 5 feet would occur in 36 nodes, and that declines 

greater than 10 feet would occur in 3 nodes. The maximum decline would 

be 10.7 feet in node 33,87. The pattern of declines was well established 

within the first 2 years of the 5-year period; during the remaining 3 

years, both the amount of decline and the areal extent of the decline 

increased.

The slight decline in water level just south of Elm Creek, near 

stream node 48,40, at the Kearney Canal diversion site would be the 

result of the decrease in return flows from the Johnson Power Return at 

stream node 4«7,28.

The effects of pumpage in the Grand Island well field, which is on 

an island in the Platte River near stream node 39,84, were not evaluated. 

Inclusion of this well field would most likely produce increased waterlevel declines in this area because of the additional water pumped from 

the aquifer.

72
Recharge from the Loup River affects the area from columns 113 

through 126 when the Platte River is dry. Evidently, when the Platte 

River is dry, water flows from the Loup River through the aquifer toward 

the dry channel of the Platte River.

The effects that the additional diversion would have on flow in the 

Platte River are shown in table 13. The measured flows are the mean 

daily flows reported for each of the months in the U.S. Geological 

Survey annual water-data report for 1957. The computed flows by the 

ground-water model and by other procedures (State of Nebraska, 1978) are 

those that would have occurred in 1957 had there been diversion of an 

additional 125,000 acre-feet that year. Whereas, without the diversion, 

the Platte River was dry at Grand Island in September and October and 

near Duncan in December. Had there been the diversion, it would have 

been dry the entire period of September through March.

The declines in water levels and streamflows projected as a result 

of additional diversion are for a period following 5 years of low 

streamflow in which the Platte River was dry for as much as 6 months 

annually. The declines projected would have been less had they been 

applied to a period of normal streamflow.

No New Ground-Water Irrigation Development After 1980

Before this set of management alternatives could be examined, the 

calibrated ground-water flow model had to be extended from September 1, 

1976, to August 31, 1980. Data on irrigated acres from 1977 to 1980 

were generated by the same procedures used in generating data on irrigated 

acres from 1931 to 1976. Climatic and streamflow data for the 1951 

through 1954 period were used in the recharge-discharge model to represent 

the 1977 through 1980 period. The use of the existing 1951-54 data 

instead of the 1977-80 data allowed a considerable savings in time and 

effort in running this and the final management alternative. The use of 

this shortcut does not impair the predictive results, since the objective 

of the predictive schemes was not 1980 water levels but water levels in 

the 1990's through 2020.

To examine this management alternative, it was necessary to know 

the acres irrigated in 1980 (fig. 7). In addition, the acres suitable 

for irrigation (fig. 18) and acres suitable but not irrigated as of 

1980 (table 14) were developed for each node. The acres suitable for 

irrigation were determined by examining both the hydrologic properties 

of the soils and the hydrogeologic limitations of the aquifer. Urban 

areas were excluded, but no areas were excluded because of hydrogeologic 

limitations of the aquifer.

The 1980 level of ground-water irrigation development is considered 

to be the zero or the no-additional-development management alternative. 

The following procedures and conditions applied in the examination of 

this alternative:

(1) The 1951 to 1970 climatic and streamflow data were used to 

obtain 1 through 20 years and 21 through 40 years of predictive data to 

be used, in turn, as input for the 40-year predictive period. Data for 

this period were selected because this period occurred after the TriCounty Canal system and Lake McConaughy became operational in the early 

1940's. Also, it contained wet, normal, and dry periods, and thus 

appeared to have been a representative period. The average annual 

precipitation for all the weather stations for the period was 0.65 

inches more than for the 1931-76 period --a period that included the 

very dry 1930's.

(2) Five different irrigation-application rates recommended by 

cooperators, in order of increasing magnitude, were considered: (a) 80 

percent of CIR; (b) low rates of 8.8 inches per year in Buffalo County 

eastward and 10.2 inches per year in Dawson and Custer Counties; (c) 

CIR; (d) medium rates of 11.0 inches per year in Buffalo County eastward 

and 12.75 inches per year in Dawson and Custer Counties; and (e) high 

rates of 13.75 inches per year in Buffalo County eastward and 16.0 

inches per year in Dawson and Custer Counties. CIR differs with soil 

group and crop. Specifically, how it differs in this study area can be 

seen in table C of "Additional Information."

76
Following the procedures and conditions mentioned, a modified 

Pumpage program was used to generate recharge and discharge data for the 

predictive period. The ground-water flow model then was run to simulate 

the 40-year predictive period, and output results indicate projected 

water levels for each of the application rates. Literally hundreds of 

combinations of time spans and application rates might have been examined. 

For this report, however, results of examination of only a few such 

combinations have been chosen for presentation and are given in plate 2a, 

2b, 2c, and 2d.

Plate 2a and 2b bracket the range of application rates and show 

what is likely to happen to water levels by the year 2000 at a low rate 

of irrigation application (80 percent of CIR) and a high rate. Plate 

2c indicates what is likely to happen at a medium rate (CIR) of irrigation 

application. Similar illustrations could have been presented for the remaining 

two application rates indicated in (b) and (d) above; they would have 

shown intermediate water-level declines relative to those on the plate 

presented.

The projected water-level declines shown in the plate are relative 

to water levels of August 31, 1976. Water levels of 1976 were used as 

the base for comparison rather than those for 1980 because they are 

calibrated water levels and, thus, are more accurately defined. The 

time span involved is about 24 years.

The declines in water level that might be expected by May 31, 2020, 

which marks the end of a predictive time span of 44 years, are indicated 

on plate 2d. The further we project into the future, the greater the 

uncertainty. Thus, no attempt is made to "bracket" a range in application 

rates, as was done for the shorter predictive period. Instead, the CIR 

application rate, which is the rate that will satisfy the consumptiveirrigation requirements of the crops, is used for the longer predictive 

period.

Comparison of plate 2a, 2b, and 2c clearly shows that both the 

areas and magnitudes of water-level declines will differ significantly 

depending on which irrigation-application rate is used. If an application 

rate of 80 percent of CIR is used (fig. 2aJ, declines of more than 20 

feet below 1976 levels can be expected in several areas 'comprising about 

10 percent of the study area. The maximum decline to be expected will 

be between 40 and 59 feet in an area north of the city of Wood River.

If an application rate exceeding CIR (fig. 2bj is used, declines of 

more than 20 feet below 1976 levels can be expected in nearly half the 

study area; declines of more than 40 feet will be common. The maximum 

decline will be between 120 and 139 feet in the area north of the city 

of Wood River.

77
If an application rate equal to CIR is used (fig. 2c), declines of 

more than 20 feet below 1976 levels can be expected in about 20 percent 

of the study area; declines of more than 40 feet can be expected in two 

areas. The maximum decline expected will be between 60 and 79 feet, 

again in the area north of the city of Wood River.

Plate 2d shows projected water-level declines by 2020, assuming an 

application rate equal to CIR. This plate can be compared logically 

only with plate 2c, with which it shares a common application rate. 

Areas and magnitudes of water-level decline on plate 2d are greater 

than those on plate 2c simply because the predictive period involved is 

longer.

Water-level declines that may be expected if the higher application 

rates are used will be so great that parts of the aquifer from Hall 

County eastward will be completely dewatered. The number of nodes that 

will be dewatered by the year 2020 for the CIR and the high irrigationapplication rates are 11 and 99, respectively.

Balance in the rates of flux into and out of the aquifer for the 

CIR application rate is indicated in table 15. A comparison of this 

table with table 11 indicates that much less water would be lost to ET 

from the shallow water-table areas under this alternative than has been 

lost historically. This is to be expected, because ET from the shallow 

water-table areas ceases when the depth to water exceeds 5 feet, and 

with the greater water-level declines, the areas within 5 feet of the 

land surface become smaller.

The projected effects that the different irrigation-application 

rates would have on streamflow in the years 2000 and 2020 are presented 

in table 16. The model-computed streamflow for May 31, 1970, represents 

the 20th year of the 1951 to 1970 climate and streamflow data that were 

used to generate the predictive recharge-discharge data for the model. 

Depletions shown, therefore, are the amounts by which the flows in 2000 

and 2020 will fail to match those in 1970.

Most of the stream nodes for which depletions are given are at 

stream-gaging locations. The first stream node listed for the Platte 

River is node 32,2 on the western edge of the study area; so, as indicated 

by the zeros in table 16, there will be no depletions at this stream 

node if this management alternative is followed. Likewise, no depletions 

will occur at stream nodes 14,80 along the North Loup River and 8,98 

along the Cedar River. At each of the remaining stream nodes, the 

expected depletions increased with the irrigation-application rate. 

Also, in nearly all cases, depletions will be higher in 2020 than in 

2000. The exception will be for the Wood River near Gibbon and near 

Chapman, where the model indicates that there would be little or no flow 

on May 31 in either year as projected depletions equal computed flows.

The depletions projected in table 16 apply only to May 31. However, 

they are typical of the magnitude of the depletions that can be expected 

for any day during the nonirrigation period of September through May.

Irrigation Development at Selected Rates from 1981 to 2020

To assume no new irrigation development after 1980, as was done in 

the previous section, is instructive but somewhat unrealistic. New 

lands will undoubtedly be brought under irrigation using ground water, 

but the rate at which this will occur is uncertain. Recognizing this 

uncertainty, both cooperators agreed that we should bracket what they 

believed to be a high development rate and a low development rate, and 

that we should consider, in addition, one intermediate rate. Thus, a 

decision was reached to examine the effects on ground-water levels of 

development rates that would annually convert to irrigation 2, 5, or 8 

percent of the acres irrigable but unirrigated at the end of each predictive year. The period simulated was from 1981 to 2020.

The effects on ground-water levels will depend significantly on the 

rate at which irrigation water will be applied. Irrigation application 

rates of 80 percent of CIR, CIR, and 120 percent of CIR were examined. 

Results are presented for all three application rates in 2000 and the 

CIR application rate in 2020.

Climatic and streamflow data for the period 1951 to 1970 were used 

to represent equivalent data for the periods 1981 to 2000 and 2001 to 

2020.

New acres assumed to be developed for irrigation each year were 

selected by counties using a random-procedures program provided by 

Richard A. Kern, Nebraska Natural Resources Commission (personal commun., 

1981). This program selected nodes and tested whether they contained 

the minimum acres required for development - - at least 10 acres of 

irrigable but unirrigated lands in terraces and flood plains, or at 

least 100 acres in uplands. If a randomly-selected node did not contain 

the minimum required acres, the node was not used and another was 

randomly selected. The selection and testing process continued until 

the required percentage of acres was selected for each county. This 

procedure was repeated for each year of the predictive period or until 

all irrigable plots of adequate size in the county had been placed under 

irrigation.

Table 17 contains information on the projected irrigated acres and 

projected irrigable but not irrigated acres for 1990, 2000, 2010, and 

2019 (the last irrigation pumping period used in the predictive period)

for annual ground-water irrigation development rates of 2, 5, and 8 

percent. An examination of this table shows significant differences in 

the projected irrigable acres, especially between the 2 and 8 percent 

development rates.

Data obtained as just described were used in a modified version of 

the Pumpage program discussed in an earlier section. Outputs from the 

Pumpage program were recharge and discharge data that were used in the 

calibrated ground-water model. Output from the ground-water model was 

then used to construct plate 3a to 3h.

Plate 3a and 3b show areas and magnitudes of water-level declines 

to be expected by the year 2000 if the rate of irrigation development 

is 2 percent. Both the area and the magnitude of the declines increases 

with the rate of application.

Plate 3c and 3d show areas and magnitude of water-level declines 

to be expected by 2000 if the rate of irrigation development is 

5 percent, and plate 3e and 3f show areas and magnitude of water-level 

declines to be expected by 2000 if the rate of irrigation development 

is 8 percent. The same pattern of increased area and increased severity 

of decline are evident in these illustrations as was mentioned for 

plate 3a and 3b.

Maximum water-level decline, regardless of which plate is consulted, 

will occur north of the city of Wood River. As for the previous management alternative, declines are projected from August 31, 1976, instead 

of 1980. By the year 2000, the maximum decline below the August 31, 

1976, water levels, for each development rate with an application rate 

of 120 percent of CIR, will be between 80 and 99 feet. Also, by 2000 

declines of 60 to 79 feet will develop northwest of Cozad and northeast 

of Grand Island if water is applied at 120 percent of CIR.

Water-level declines that may be expected by 2020, if rates of 

irrigation development are 2 percent and 8 percent, respectively, are 

shown in plate 3g and 3h. For each rate of development, only the CIR 

application rate was presented. Because of the tentative nature of a 

40-year projection and the need for economizing space in this report, 

illustrations are not included for the 5-percent development rate nor for 

application rates of 80 and 120 percent of CIR.

In plate 3g water-level declines of 100 to 119 feet are projected 

for the year 2020 north of the city of Wood River and along the western 

boundary of Merrick County. Such declines are more extensive and up to 

40 feet greater than declines projected through the year 2000 for the 

same development and application rates (plate 3b).

83
As plate 3h indicates, a development rate of 8 percent through the 

year 2020 will result in much more extensive water-level declines than 

any of the management alternatives previously described. These declines 

are up to 60 feet greater than those representing the same development 

and application rates for the year 2000. Also, declines of 80 to 99 

feet will occur in a small area northwest of Cozad. Maximum water-level 

declines by the year 2020 will be 120 to 139 feet north of the city of 

Wood River and northeast of Grand Island.

The rates of flux generated by the ground-water model, assuming an 

application rate equal to CIR and annual irrigation-development rates of 

2, 5, and 8 percent, are listed in table 18. The rates are for the 

1990, 2000, 2010, and 2019 irrigation pumping periods and for the 2020 

nonirrigation pumping period. A comparison of data in this table to 

data in table 14 indicates the projected effects of additional groundwater irrigation development. The amount of pumping will have increased 

by, in some cases, as much as a factor of two.

Fluctuations in pumping, recharge, storage, and the other parameters 

listed in table 18 can be explained, in part, by variations in the 

climatic data used as input for the 40-year interval. Thus, it is 

useful to compare rates of flux for years for which the same climatic 

and streamflow data were used. These are, in one case, the years 1960 

(from table 11), 1990, and 2010 and, in another case, the years 1970 

(from table 11), 2000, and 2020. Such comparisons indicate that with 

additional development the volume of pumpage and water removed from the 

aquifer (storage) increase, that flow from the stream to the groundwater system (inflow) likewise increases, and that recharge from infiltration through the soil zone to the aquifer decreases. Also, the amount 

of water loss to ET decreases as development increases. The net effect 

is a decrease in the volume of ground water stored in the aquifer and a 

lowering of water levels.

The water-level declines will become larger as the application 

rates and the irrigation-development rates increase, and parts of the 

aquifer east of the Buffalo-Hall County line will be dewatered. The 

number of nodes that will be dewatered by the year 2020 with 2, 5, and 

8 percent irrigation-development rates and with an application rate 

equal to CIR will be 15, 25, and 28, respectively.

The projected effects of different rates of irrigation development 

and of different rates of application on streamflow are shown in table 19. 

The depletions are compared to computed streamflow of May 1970 for 

reasons discussed previously in the section "No New Ground-Water Irrigation 

Development after 1980." Data in this table indicate that increased 

streamflow depletions accompany increased development and application 

rates.

SUMMARY OF CONCLUSIONS

Maps and tables presented in this report indicate that water levels 

will decline in the future throughout much of the study area even without 

additional development beyond the 1980 level unless reductions are made 

in the volume of ground water used. These reductions might be attained 

either through cutbacks in the acreages irrigated or through cutbacks in 

the amount of ground water applied per acre. A variety of methods can 

be employed to accomplish these reductions; some have been previously 

discussed.

Declines ranging from 0 to about 139 feet will occur in Hall County 

and in Merrick County before 2020, depending on the assumed rate of 

ground-water development (up to 8 percent per year). Similarly, declines 

ranging from 0 to about 79 feet will occur before 2020 from Buffalo 

County westward. Declines of up to about 99 feet will occur by the year 

2020 a few miles northeast of Gothenburg for the development rate of 8 

percent per year.

Water-level declines occur in areas where aquifer discharge exceeds 

aquifer recharge. As areas where the depth to water exceeds 5 feet 

increase, the volume of ET salvage will reach a maximum, and ET losses 

from the ground water will decrease and approach a minimum. Also, 

additional ground water will be removed from storage in order to satisfy 

pumpage requirements. Finally, as water levels decline, more surface 

water will move into the aquifer and less ground water will move into 

the streams.

The pumpage, storage (water removed from storage), and inflow 

(water moving from the stream to the aquifer) rates will increase with 

additional ground-water development; however, the rates of recharge, ET 

losses from ground water, and outflow (water moving from the aquifer to 

the stream) will decrease.

The relationship between the aquifer and the surface-water system 

is important in determining future water levels in the study area. The 

simulations indicate that the movement of water from the streams to the 

aquifer will increase with time and that the rate of increase will be 

proportional to the rate of new irrigation development. Also, decreases 

in streamflow probably will occur because of additional surface-water 

diversions, additional ground-water development west of the study area, 

and changing farming practices west of the study area. These decreases 

in streamflow may affect water levels if the streamflow reductions are 

large enough to significantly lower the stream stages.

ADDITIONAL INFORMATION

The following tables provide data pertaining to the report area, or 

to methodology used in the report that may be useful but not essential 

for an understanding of the report.

Table A gives results of discharge measurements made during seepage 

surveys of streams in the report area. These results have been used in 

the calibration of the model and in interpreting ground-water/surfacewater relationships.

Table B indicates the methods used in estimating hydraulic conductivity and specific yield from descriptions of materials comprising a 

lithologic unit. Specific yield is estimated from grain-size class or 

range alone. Hydraulic conductivity, however, is estimated from grainsize class or range and either the estimated degree of sorting or the 

estimated silt content. Judgment is exercised in determining which of 

the values to use, or whether to use some intermediate value.

Table C is presented to show the type of output data generated by 

the soil-water program for the 15 weather stations in the report area. 

Data are given in the table for only three of the weather stations -- 

Gothenburg, Kearney, and Central City. Data for the Gothenburg station 

typically represents weather conditions in the western part of the 

report area; those from the Kearney station, weather conditions in the 

central part; and those from the Central City station, weather conditions 

in the eastern part.

EXECUTIVE SUMMARY

TC5872123.37s EXECUTIVE SUMMARY 7

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on

a relative (not an absolute) basis. Relative elevation information between sites of close proximity

should be field verified. Sites with an elevation equal to or higher than the target property have been

differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed

data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.

ADDITIONAL ENVIRONMENTAL RECORDS

Other Ascertainable Records

FUDS: The Listing includes locations of Formerly Used Defense Sites Properties where the US Army

Corps Of Engineers is actively working or will take necessary cleanup actions.

 A review of the FUDS list, as provided by EDR, and dated 05/15/2019 has revealed that there is 1 FUDS

 site within approximately 1 mile of the target property.

SEMS: Superfund Enterprise Management System

SEMS (Superfund Enterprise Management System) tracks hazardous waste sites, potentially hazardous waste sites,

and remedial activities performed in support of EPA’s Superfund Program across the United States. The list was

formerly know as CERCLIS, renamed to SEMS by the EPA in 2015. The list contains data on potentially hazardous

waste sites that have been reported to the USEPA by states, municipalities, private companies and private persons,

pursuant to Section 103 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

This dataset also contains sites which are either proposed to or on the National Priorities List (NPL) and the

sites which are in the screening and assessment phase for possible inclusion on the NPL.

SEMS-ARCHIVE: Superfund Enterprise Management System Archive

TC5872123.37s Page GR-2

GOVERNMENT RECORDS SEARCHED / DATA CURRENCY TRACKING
SEMS-ARCHIVE (Superfund Enterprise Management System Archive) tracks sites that have no further interest under

the Federal Superfund Program based on available information. The list was formerly known as the CERCLIS-NFRAP,

renamed to SEMS ARCHIVE by the EPA in 2015. EPA may perform a minimal level of assessment work at a site while

it is archived if site conditions change and/or new information becomes available. Archived sites have been removed

and archived from the inventory of SEMS sites. Archived status indicates that, to the best of EPA’s knowledge,

assessment at a site has been completed and that EPA has determined no further steps will be taken to list the

site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or

other considerations require a recommendation for listing at a later time. The decision does not necessarily mean

that there is no hazard associated with a given site; it only means that. based upon available information, the

location is not judged to be potential NPL site.

INST CONTROL: Nebraska’s Institutional Control Registry

A list of sites within Nebraska that have institutional controls. According to the Environmental Protection Agency

(EPA), institutional controls are "non-engineering measures designed to prevent or limit exposure to hazardous

substances left in place at a site, or assure effectiveness of the chosen remedy. Institutional controls are usually,

but not always, legal controls, such as easements, restrictive covenants, and zoning ordinances." In short, institutional

controls are a type of environmental covenant typically used when property is to be cleanup to a level determined

by the potential environmental risks posed by a planned use, rather than to unrestricted use standards. This method

of control has proven to be both environmentally and economically beneficial.

"NDEQ defines a brownfields site as subpart (A) of CERCLA ? 101(39): ’Real property, the expansion, redevelopment,

or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant,

or contaminant.’ This is a broad-based approach to capture all potential brownfields sites. In the event that

CERCLA 128(a) State Response Program funds are utilized - for example, conducting a Section 128(a) Assessment

- the exclusions, site-by-site determinations, and further definitions as provided by the law would need to be

met. This would be done on a site-by-site basis." A preliminary Survey and Inventory of Brownfields Sites in

Nebraska was constructed based on previously submitted information including sites named specifically by city

representatives. The list was built on facility characteristics, which were founded on previous, broad-based contamination

experience. Additions to the inventory were made by looking for other sources of potential brownfields sites using

Standard Industrial Classification (SIC) codes. A general sector list was constructed to serve as an inventory

guide. This list shows all of the different types of sites that are within the inventory (sorted by SIC code),

and the number of sites there are of each type. Color-coated blocks, which group together similar SIC codes and

the sites that they encompass also sort the sectors.

EPA WATCH LIST: EPA WATCH LIST

EPA maintains a "Watch List" to facilitate dialogue between EPA, state and local environmental agencies on enforcement

matters relating to facilities with alleged violations identified as either significant or high priority. Being

on the Watch List does not mean that the facility has actually violated the law only that an investigation by

EPA or a state or local environmental agency has led those organizations to allege that an unproven violation

has in fact occurred. Being on the Watch List does not represent a higher level of concern regarding the alleged

violations that were detected, but instead indicates cases requiring additional dialogue between EPA, state and

local agencies - primarily because of the length of time the alleged violation has gone unaddressed or unresolved.

contains a wide variety of sites. Some properties are heavily contaminated while others were contaminated but

have since been cleaned up. Still others have not been fully investigated yet, and may require little or no remediation.

Inclusion in the 2020 Universe does not necessarily imply failure on the part of a facility to meet its RCRA obligations.

When Congress passed the Clean Air Act Amendments of 1990, it required EPA to publish regulations and guidance

Rule (RMP Rule) was written to implement Section 112(r) of these amendments. The rule, which built upon existing

industry codes and standards, requires companies of all sizes that use certain flammable and toxic substances

to develop a Risk Management Program, which includes a(n): Hazard assessment that details the potential effects

of an accidental release, an accident history of the last five years, and an evaluation of worst-case and alternative

accidental releases; Prevention program that includes safety precautions and maintenance, monitoring, and employee

training measures; and Emergency response program that spells out emergency health care, employee training measures

and procedures for informing the public and response agencies (e.g the fire department) should an accident occur.

HIST FTTS INSP: FIFRA/TSCA Tracking System Inspection & Enforcement Case Listing

A complete inspection and enforcement case listing from the FIFRA/TSCA Tracking System (FTTS) for all ten EPA

regions. The information was obtained from the National Compliance Database (NCDB). NCDB supports the implementation

of FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act) and TSCA (Toxic Substances Control Act). Some

EPA regions are now closing out records. Because of that, and the fact that some EPA regions are not providing

EPA Headquarters with updated records, it was decided to create a HIST FTTS database. It included records that

may not be included in the newer FTTS database updates. This database is no longer updated.

UMTRA: Uranium Mill Tailings Sites

Uranium ore was mined by private companies for federal government use in national defense programs. When the mills

shut down, large piles of the sand-like material (mill tailings) remain after uranium has been extracted from

the ore. Levels of human exposure to radioactive materials from the piles are low; however, in some cases tailings

were used as construction materials before the potential health hazards of the tailings were recognized.

EDR HIGH RISK HISTORICAL RECORDS

EDR Exclusive Records

EDR MGP: EDR Proprietary Manufactured Gas Plants

The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants)

compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’s

to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture

of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production,

such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds

are potentially hazardous to human health and the environment. The byproduct from this process was frequently

disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil

and groundwater contamination.
