RE: Environmental Covenant for Resurrection Mining Company's Zone C Properties , 

Dear Carl, 

The enclosed Environmental Covenant for Resurrection Mining Company's Zone C properties has now 

been executed by all parties and filed with the Lake Coimty Recorder. 

As you know, the Colorado Envirormiental Covenant statute, C.R.S. § 25-15-321 to 327, requires that 

local governments notify the CDPHE when they receive applications affecting land use or development 

of land that is subject to an envirormiental covenant. In turn, the CDPHE must review the proposed 

application and provide timely advice to the local govemment as to whether the application is consistent 

with the terms of the covenant or restrictive notice. 

Therefore, we respectfully request that you forward the enclosed environmental covenant to appropriate 

Lake Coimty Departments to assist them in identifying applications that affect the land use or 

development of the parcels described in the covenant. 

Please don't hesitate to contact me or Doug Jamison with any questions or comments.

GROUNDWATER SAMPLING PROTOCOLS 

Groundwater Sampling and Analysis Plan 

This attachment specifies the groundwater sampling procedures for purposes of terminating or 

modifying an Environmental Covenant for groundwater use restrictions, as specified in 

Appendix Fl . For purposes of the protocol, a "property" is defmed as a portion of a claim, an 

individual claim or contiguous claims not exceeding 35 acres in total area for which the 

groundwater use restrictions of an aquifer are to be terminated. The followings sections describe 

the groundwater sampling requirements, methods, sample analysis, and quality assurance that 

will support such termination or modification. Altemate groundwater sampling procedures and 

analysis methods for a property may be proposed in a site-specific sampling plan for the 

property, subject to approval by the State. 

1.1 Groundwater Sampling Requirements 

One groimdwater sample will be collected from a well completed in the aquifer of the 

hydrogeologic unit (alluvial, unconsolidated sedimentary deposits, or bedrock) proposed for 

beneficial use underlying each property. For alluvial or unconsolidated sedimentary deposits, the 

hydrogeologic unit is defined as the aquifer with the same lithology and within the same surface 

water hydrologic divide. The bedrock hydrogeologic unit is defined as the aquifer within the 

same geologic formation and stmcture. The groundwater use restrictions will be terminated or 

modified for a properfy for only that aquifer of the hydrologic unit in which the well is 

completed. 

The groundwater sample from the well will be analyzed for constituents that are relevant to the 

Califomia Gulch Superfimd Site for which numeric groundwater qualify standards have been 

established by the State for the proposed beneficial use at the time of the application for 

termination or modification of the Environmental Covenant, ,hereafter referred to as the Numeric 

Standards. The constituents that are relevant to the Califomia Gulch Superfimd Site and the 

current Numeric Standards are presented in Table 1 for drinking/domestic or agricultural uses. 

The groundwater in the aquifer will be determined acceptable for the proposed use, and the 

Environmental Covenant restricting groundwater will be terminated for the property or modified 

to allow a particular beneficial use, if the constituent concentrations of the sample from the well 

are less than the Numeric Standards for all beneficial uses (in the event of termination) or the 

particular beneficial use (in the event of modification). 

1.2 Groundwater Sampling Methods 

The groundwater sample from the well will be collected according to the methods described in 

SOP No. 4-Ground Water Well Sampling. Non-dedicated or non-disposable sampling 

equipment will be decontaminated prior to collection of the sample according to the methods 

described in SOP No. 1-Decontamination. Sample collection documentation, sample

containment, preservation, identification, labeling and shipping will be performed according to 

the procedures described in SOP No. 7- Sample Handling, Documentation, and Analysis. 

13 Laboratory Analytical Methods 

Samples will be analyzed for the parameters for which Numeric Standards have been established 

for the proposed beneficial use. Sample container, preservation, and holding times are provided 

in SOP No. 7-Sample Handling, Documentation, arid Analysis. The laboratory will be required 

to process all samples submitted according to the specific protocols for sample custody, holding 

times, analysis, reporting and associated laboratory quality assurance. Laboratory quality 

assurance checks will include the use of blank, spiked, split, and duplicate samples, calibration 

checks, and intemal standards. Designated laboratory persoimel will be required to ensure that 

QA/QC procedures are achieved. The laboratory or laboratories for constituent analysis must be 

accredited by the Colorado Certification Program. Laboratory calculations and data review will 

be performed by the laboratory in accordance with the procedures described by the analytical 

method. The laboratory will review the results of the laboratory QC analyses, instmment 

calibration and maintenance records, calculations, and the record of sample custody (including 

holding times) within the laboratory.

DECONTAMINATION 

1.0 INTRODUCTION AND TYPES OF CONTAMINATION 

The purpose of this document is to define the standard procedure for decontamination associated 

with environmental investigation for this Califomia Gulch Superfimd Site. This procedure is 

intended to be used with other SOPs. 

1.1 Site and/or Sample Cross-Contamination 

The overall objective of multimedia sampling programs is to obtain samples which accurately 

depict the chemical, physical, and/or biological conditions at the sampling site. Extraneous 

contaminant materials can be brought onto the sampling location and/or introduced into the 

medium of interest during the sampling program (e.g., by contacting water with equipment 

previously contaminated at another sampling site). Trace quantities of these contaminant 

materials can thus be captured in a sample and lead to false positive analytical results and, 

ultimately, to an incorrect assessment of the contaminant conditions associated with the site. 

Decontamination of non-dedicated or non-disposable sampling equipment (e.g., bailers, pumps, 

and tubing) and field support equipment (e.g., drill rigs, vehicles) is required. To ensure that 

sampling cross-contamination is prevented, and that on site contaminants are not carried offsite. 

2.0 PROCEDURES 

2.1 Equipment List 

The following is a list of equipment that may be needed to perform decontamination: 

Bmshes 

Wash tubs 

Buckets 

Scrapers 

Steam cleaner or high-pressure washer 

Paper towels 

Alconox detergent (or equivalent) 

Potable water 

Deionized or distilled water 

Garden type water sprayers 

Clean plastic sheeting and/or trash bags

12 of 29 COV RS152.00 DSO.OO Lake Countv Recorder 

2.2.1 Sampling Equipment 

The following steps will be used to decontaminate non-dedicated or non-disposable sampling 

equipment (including reusable filter apparatus): 

Personnel will dress in suitable safefy equipment to reduce personal exposure (e.g., latex 

gloves, safefy glasses, etc.). 

Gross contamination on equipment will be scraped off at the sarapling or constraction site. 

Equipment that will not be daraaged by water will be washed with an Alconox solution or 

low-sudsing detergent and potable water and scmbbed with a bristle bmsh or similar 

utensil (if possible). Equipment will be triple rinsed with potable water followed by a 

triple rinse with deionized or distilled water. 

Following decontamination, equipment will be placed in a clean area, on or in clean plastic 

sheeting to prevent contact with contaminated soil. If the equipment is not used immediately, the 

equipment will be covered or wrapped in plastic sheeting or heavy dufy trash bags to minimize 

potential airbome contamination. 

2.2.2 Submersible Pumps 

If non-dedicated submersible pumps are used they will be decontaminated between wells. The 

outside of the pump and hose will be tripled rinsed with deionized or distilled water. Deionized 

or distilled water will be pumped through the pump and hose. The volume of deionized or 

distilled water pimiped through will be at a minimum equal to three times the volume of fluid 

that could be contained by the pump and hose. 

2.2.3 Water Level Probes 

Electric water level probes will be decontaminated by rinsing with deionized or distilled water or 

by wiping the probe during removal with paper towels wetted with deionized or distilled water. 

The water level probe will be placed in a plastic bag after decontamination. 

2.2.4 Sensitive Equipment 

Sensitive equipment that may be damaged by water will be carefully wiped clean using paper 

towels and detergent water or spray bottle and towel and rinsed with deionized or distilled water. 

Care will be taken to prevent any equipment damage. 

2.2.5 Drilling and Heavy Equipment 

Drilling and heavy equipment will be decontaminated at a designated decontamination area for 

large equipment. The following steps will be used to decontaminate drilling and heavy 

equipment: 

Persoimel will dress in suitable safety equipment to reduce personal exposure (e.g., gloves, 

safety glasses or splash shields, etc.).

13 of 29 COV RSI.52.00 DSO.OO Lake Count?Recorder 

Equipment showing gross contamination or having drill cuttings caked on will be scraped off 

with a flat-bladed scraper at the sampling or constmction site. 

Equipment, such as drill rigs, augers, drill bits, and shovels will be sprayed with potable 

water by a high-pressure washer. Care should be taken to adequately clean the insides of 

the hollow-stem augers and backhoe buckets. 

Following decontamination, drilling equipment will be placed on the clean drill rig and moved to 

a clean area. If the equipment is not used immediately, it should be stored in a designated clean 

area. 

2.2.6 Equipment Leaving the Site 

Vehicles used for non-intmsive activities shall be cleaned on an as needed basis. Constmction 

equipment such as earth moving equipment, tmcks, drilling rigs, backhoes, trailers, etc., will be 

pressure washed at the designated decontaraination area before the equipment is removed from 

the site. 

2.2.7 Wastewater 

Used wash and rinse solutions may be discharged to the ground at the sampling site 

2.2.8 Other Wastes 

Solid wastes such as paper towels and used filters will be sealed in plastic garbage bags and 

disposed of in a sanitary landfill. 

23 Documentation 

Sampling personnel will be responsible for documenting the decontamination of sampling and 

drilling equipment. The documentation will be recorded with waterproof ink in the sampler's 

field notebook with consecutively numbered pages. The information entered in the field book 

conceming decontamination should include the following:

35 9748 10/1/201211:01 AM Patricia Berger 

16 of 29 COV RS152.(X) DSO.OO Lake County Recorder 

Before any evacuation or sampling begins, all well probes, bailers, and other sarapling devices 

shall be decontaminated. If dedicated equipment is used, it should be rinsed with deionized 

water. Dedicated downhole pumps will not be decontaminated. A discussion of equipment and 

personnel decontamination is contained in SOP No. 1, Decontamination, and in the site Health 

and Safefy Plan. 

2.2.2 Instrument Calibration 

Electronic equipment used during sampling includes a pH meter with temperature scale, a 

conductivity meter and a turbidify meter. Before going into the field, the sampler shall verify 

that all of these are operating properly. The pH and conductivify meters require calibration and 

calibration checks every day prior to use. The turbidify meter requires a' calibration check by 

reading measurements cells of a known value. Calibration times and readings will be recorded in 

a notebook and/or on Calibration Data Sheet, which are to be kept by the field sampler. 

2.2 J Evacuate Well 

The purpose of well purging is to remove stagnant water frora the well to obtmn representative 

water from the geologic formation being sampled while minimizing disturbance to the collected 

samples. Before a sample is taken, the well will be purged until a miniraum of three well casing 

volumes have been removed and field parameters have stabilized, or until a maximum of five 

well volumes have been removed. Purging will be considered completed if the well is pumped 

or bailed dry. A well should be pumped at a rate no faster than approximately 1 gallon per 

minute if it has a tendency to dry up prior to evacuating three casing volumes. Evacuated well 

water may be disposed of at the well site in a manner that does not cause mnoff. 

Before well purging begins, the following procedures are to be performed at each well: 

Note the condition of the outer well casing, concrete well pad, protective posts (if present), 

and any other unusual conditions in the area around the well. 

If bailing place clean plastic sheeting around the well. 

Open the well. 

Note the condition of the inner well cap and casing. 

Measure (to nearest 0.01 foot) and record depth of static water level from the measuring 

point on the well casing and indicate time. Record what the measuring point is (i.e., 

notch on north side, top of PVC well casing). 

Calculate volume of water in the well casing in gallons based on feet of water and casing 

diameter. (See Section 2.4.3 for calculation of volumes.) 

From the above calculation, calculate the three casing volumes to be evacuated. 

Obtain an initial sample (which is not retained) from the bailer or purge pump for field 

measurements (temperature, conductivity, and pH measurements) and observation of 

water quality.

Evacuate three volumes of water in casing with a bailer or purap. Take temperature, specific 

conductance, and pH measurements after evacuation of each well volume to confirm that 

the water chemistry has stabilized. Generally, pH values within ±0.2 pH unit and 

conductivity and temperature readings within ±10 percent between consecutive readings 

indicate good stability of the water chemistry. If the chemistry is not stable, continue 

purging up to a maximum of five well volumes, measuring pH and specific conductance 

after each one half well volume. 

When evacuating a well using a pump, the pump intake should be placed: 

for low recovery wells (wells that can be pumped dry), place pump intake at bottom of 

screened interval. 

for high recovery wells (little drawdown with pumping), place pump at or slightly 

above the middle of the screened interval to ensure the removal of stagnant water from 

the well bore. 

If the well is bailed or pumped dry during evacuation, it can be assumed that the purpose of 

removing 3 well volumes of water has been accomplished, that is, removing all stagnant 

water that had prolonged contact with the well casing or air. If recovery is very slow, 

samples may be obtained as soon as sufficient water is available. 

2.2.4 Obtain Water Samples 

Obtain samples for chemical analysis within 2 hours after purging is completed, if possible. For 

slow recovering wells, the sample shall be collected immediately after a sufficient volume is 

available (water has recovered to screened interval). The water quality samples shall be taken 

frora within the well screen interval. 

The following sampling procedure is to be used at each well: 

1. Assemble decontaminated sampling equipment. If bailers are used, new nylon or 

polypropylene rope will be used for each well for each sampling event. Assemble 

the filtering apparatus. 

2. Make sure that saraple labels have been filled out for each well. 

3. Lower the bailer slowly and gently into contact with the water in the well. Lower 

the bailer to the same depth in the well each time, within the screened interval. 

Retrieve the bailer smoothly and empty the water in a slow steady stream into the 

containers. If submersible or bladder pumps are utilized to collect samples, start 

the pump and fill the sample bottles as described below. 

4. Triple rinse the sample containers with sample water and then fill the saraple 

bottles. If not enough sample water is available to perform die triple rinse, then at 

a minimum a single rinse will be performed and will be recorded in the field 

logbook and/or data sheet. Cap the sample containers quickly. If sample bottles 

are pre-preserved, fill the sample bottles without rinsing. Add preservative if the 

bottle is not pre-preserved. Do not allow the sample containers with preservatives 

to overflow. See Section 2.2.5 for details on field filtering.

I8of29 COV RSI52.00 DSO.OO LaSSt^ Lak R e County Recorder 

5. Slowly pour an unfiltered portion into the sample container for field parameter 

(pH, specific conductance, temperature, and tuAidity) analyses and perform the 

in-field analyses and record. 

6. Place saraples on ice in a cooler. 

7. Record time of sampling. 

8. Replace and lock well cap. 

9. Complete field documentation. 

2.2.5 Filtering Samples 

Saraples for metals analyses will be filtered during the field sampling event by using a 

disposable filter apparatus and peristaltic or hand vacuum pump. 

The following procedure is to be used for filtering: 

Assemble filter device according to manufacturer's instmctions. 

Prior to the collection of aliquots, flush the filter with approximately 100 to 200 

milliliters of groundwater. Filter sample either by pouring sample in the top portion of 

filter unit or pumping through an in line filter using a peristaltic pump. Sample may also 

be filtered by attaching the in-line filter to the submersible pump discharge. 

Triple rinse the sample containers with filtered sample water and then fill the sample 

bottles. If not enough sample water is available to perform the triple rinse, then at a 

rainiraura a single rinse will be performed and will be recorded in the field logbook 

and/or data sheet. Cap the sample containers quickly. If saraple bottles are prepreserved, fill the sample bottles without rinsing. Add preservative if the bottie is not 

pre-preserved. Do not allow the sample containers with preservatives to overflow. 

Place the used filter membrane or disposable filter equipment in a Ziploc® bag for 

disposal with the personal protective equipment. 

Any reusable filtering equipment will be decontaminated in accordance with SOP No. 1. 

2.3 Sample Handling 

Sample containers and preservatives are specified in SOP No. 7, Sample Handling, 

Documentation and Analysis. Samples will be labeled and handled as described in SOP No. 7. 

2.4 Documentation 

2.4.1 Groundwater Data Sheet 

A groundwater data sheet for groundwater samples (Appendix A) will be completed at each 

sampling location. The data sheet will be completely filled in. If items on the sheet do not apply

SOP Date: February 2008 

SAMPLE HANDLING, DOCUMENTATION, AND ANALYSIS 

1.0 PURPOSE AND SCOPE 

The purpose of this document is to define the standard protocols for sample handling, 

documentation, and analysis for the Califomia Gulch Superfimd Site. This procedure is 

intended to be used together vidth other SOPs and is referenced in all SOPs that apply to 

sampling. 

2.0 PROCEDURES FOR SAMPLE HANDLING, DOCUMENTATION, AND ANALYSIS 

2.1 Sample Identification and Labeling 

Saraples collected during monitoring, investigations, or remediation activities will be assigned 

unique sample identification numbers. Each sample identification number will identify the 

organization collecting the sample or the program under which it is collected, sampling location, 

type of sample, and sampling sequence for each sample. These numbers are required for 

tracking the handling, analysis, and verification br validation status of all samples collected 

during monitoring. In addition, the sample identification numbers will be input into the project 

database to identify analytical results received fi-om the laboratory. 

Sample identification numbers that are assigned will be divided into four fields as shovm in the 

following example: 

M-CGW 1-01-900423 

The first field is one character in length and identifies the company conducting the sampling. 

The second field is an alphanumeric code identifying the location of the sample and the last letter 

of this field indicates the matrix (e.g., CGMl indicates Califomia Gulch Well No. 1, the second 

W indicates a water matrix). The next field identified is the type of sample being collected; this 

is used to identify whether the sample is a primary or grab sample, a composite sample, field 

duplicate, field blank, or equipment rinsate. The final field contains the date in a year-month-day 

format. For example, the sample identified above was collected on April 23, 1990. 

Each sample that is collected in the field will be labeled for future identification. Sample labels 

will be filled out as completely as possible by a meraber of the sarapling team prior to the start of 

the day's field sampling activities. The date, time, sampler's signature, and the last field of the 

sample identification number should not be completed until the sample is actually collected. All 

sample labels will be filled out using waterproof ink. At a minimum, each label will contain the 

following information:

Sampler's company affiliation; 

Site location; 

Saraple identification; 

Date and tirae of sample collection; 

Method of preservation used; 

Sample matrix; and 

Sampler's initials. 

2.2 Sample Containers, Preservatives, and Holding Times 

2.2.1 Sample Containers 

Proper sample preparation practices will be observed to minimize saraple contamination and 

potential repeat analyses due to anomalous analytical results. Prior to sarapling, coramerciallycleaned sample containers will be obtained fi-om the analytical laboratory. The bottles will be 

labeled as described in the previous section to indicate the type of sample and sample matrix to 

be collected. Sample bottles can be either pre-preserved fi-ora the laboratory or preservatives can 

be added in the field during sample collection. 

2.2.2 Sample Presen'ation 

Samples are preserved in order to prevent or minimize chemical changes that could occur during 

transit and storage. Sample preservation should be performed immediately upon sample 

collection to ensure that laboratory results are not compromised by improper coordination of 

preservation requirements and holding times. Samples will be preserved imraediately and stored 

on ice in coolers prior to shipping. Saraple preservation requirements are based on the most 

current publication of 40 CFR, Part 136.3 and are provided in Table 1. 

2.23 Sample Holding Times and Analyses 

Sample holding times are established to minimize chemical changes in a sample prior to analysis 

and/or extraction. A holding time is defined as the maximum allowable time between sample 

collection and analysis and/or extraction, based on the nature of the analyte of interest and 

chemical stability factors. Holding tiraes applicable for analytes are listed in Table I. Samples 

should be sent to the laboratory as soon as possible after collection by hand delivery or an 

ovemight courier service to minimize the possibility of exceeding holding times. 

For most samples, preservation by cooling to 4°C is required immediately after collection while 

the samples are held for shipment and during shipment to the laboratory. 

2.3 Sample Preparation and Shipping 

After collection, samples will be labeled and prepared as described in the previous discussion, 

and placed on ice in an insulated cooler. The sample containers will be placed in re-closeable 

plastic storage bags. Samples will then be placed right side up in a cooler with ice for delivery to 

the laboratory. The ice in the cooler will be double-bagged. The coolers will be taped shut and 

25 
3 5 9748 10/1/2012 11:01 AM Patricia Berger 

26 of 29 COV RS152.00 DSO.OO Lake County Recorder 

chain-of-custody seals wall be attached to the outside of the cooler to ensure that the cooler 

cannot be opened without breaking the seal. Final packaging and shipping will be conducted in 

corapliance with current lATA Resolution 618 and DOT 49 CFR Part 171 Regulations. 

All samples will be shipped for laboratory receipt and analysis vidthin the holding times specified 

in Table 2. This may require daily shipment of samples with short holding times. 

2.4 Sample Documentation and Tracking 

This section describes the information that should be provided in field notes and sample Chainof-Custody documentation. 

2.4.1 Field Notes 

Documentation of observations and data acquired in the field provide information on sample 

acquisition, field conditions at the time of sampling, and a permanent record of field activities. 

Field observations and data collected during routine monitoring activities will be recorded with 

waterproof ink in a permanently bound weatherproof field log book with consecutively 

mmibered pages or on field data sheets as specified in the project SOPs. 

Field notebook and/or data sheet entries will, at a minimum, include the information listed 

below. Relevant SOPs should be consulted to supplement this list. 

Project name; 

Location of sample; 

Data and time of sample collection; 

Sample identification numbers; 

Description of sample (matrix sampled); 

Sample depth (if applicable); 

Sample methods, or reference to the appropriate SOP; 

Field observations; 

Results of any field measurements, such as depth to water, pH, temperature, specific 

conductance; and 

Personnel present. 

Changes or deletions in the field book or on the data sheets should be recorded with a single 

strike mark, and remain legible. Sufficient information should be recorded to allow the sampling 

event to be reconstmcted without having to rely on the collector's memory. 

All field books will be signed on a daily basis by the person who has made the entries. Anyone 

making entries in another person's field book will sign and date those entries. 

2.4.2 Sample Chain-Of-Custody 

During field sampling activities, traceability of the sample must be maintained Irom the time the 

samples are collected until laboratory data are issued. Establishment of traceability of data is 

26 
3 5 9 748 10/1/201211:01 AM PairiciaBerger 

27 of 29 COV R$l52.00 DSO.OO Lake County Recorder 

cmcial for resolving fiiture problems if analytical results are called into question and for 

minimizing the possibilify of sample mix-up. Initial information conceming collection of the 

samples will be recorded in the field log book or on data sheets as described above. Information 

on the custody, transfer, handling and shipping of samples will be recorded on a Chain-ofCustody (COC) form. 

The sampler is responsible for initiating and filling out the COC form. The COC will be signed 

by the sampler when he or she relinquishes the samples to anyone else. A COC form will be 

completed for each set of water quality samples collected, and will contain the following 

information: 

Sampler's signature and affiliation 

Project number 

Date and time of collection 

Sample identification number 

Saraple type 

Analyses requested 

Number of containers 

Signature of persons relinquishing custody, dates, and times 

Signature of persons accepting custody, dates, and times 

Method of shipment 

Shipping air bill number (if the samples are shipped) 

Any additional instmctions to the laboratory. 

The person responsible for delivery of the samples to the laboratory will sign the COC form, 

retain the third copy of the form, document the method of shipment, and send the original and 

the second copy of the form with the samples. Upon arrival at the laboratory, the person 

receiving the samples will sign the COC form and retum the second copy to the Project 

Manager. Copies of all COC documentation will be compiled and maintained in the central files. 

The original COC forms will reraain with the samples until the time of final disposition. After 

retuming samples for disposal, the laboratory will send a copy of the original COC to the 

Operator. This will then be incorporated into the central files.
