## I. Introduction

N onpoint source pollution (NPS) has a major impact on Maine’s lakes, rivers, streams and

marine waters. Unlike pollution from point sources, such as industrial and sewage treatment plants, NPS pollution comes from many diffuse sources

. I t is caused by rainfall or snowmelt moving over and through the ground and picking up natural and human

- made pollutants

, such

as fertilizer , road salt, sediment, oil and bacteria

, along the way. Eventually these contaminants end up in waterbodies , where they can threaten drinking water supplies, cause nuisance algal blooms, diminish recreation al activit ies, and endanger aquatic life and habi tat

.

The Maine Department of Environmental Protection (DEP) coordinates the State of Maine Nonpoint Source Pollution Program (38 M R S 410) to restore and protect waters impaired and
threatened 1 by nonpoint source pollution. In this NPS Program Plan

, DEP establishes the overall
strategy that Maine will use over the next five years (2015

- 2019) to control and prevent NPS pollution to the state ’s waters. The Plan identifies :

 P rograms, strategies and resources state agenc ies use to address Maine’s most pressing NPS water pollution control problems ;

 DEP’s approach to strategically focus watershed protection and restoration work in NPS Priority wa tersheds;

 F und ing opportunities and partnerships critical to protect ing and improv ing Maine’s lakes

, streams, r ivers, and marine waters ; and

 F ive

- year objectives, actions and milestones to make progress achieving the long

- term goals of Maine’s NPS management program

.

The U.S. Environment al Protection Agency (EPA) requires states to have an updated NPS Management Plan in place to qualify for federal Section 319 grant awards under the Clean

Water Act. In 2013, EPA issued 319 program guidelines describing key component s to be
included in an effectiv e state NPS management program . Appendix 1 summari z e s how these key elements have been incorporated into Maine’s Plan.

1 The use of the term, ‘threatened’, in this document refer s to unimpaired waters that are subject to potenti al impacts from NPS pollution. The term is not intended to be used as described in Mai ne’s Integrated Report, where waters are listed as ‘threatened’ for Clean Water Act §303(d) listing purposes if those waters are anticipated to fall into non

- attainment with the next listing cycle of two years

## II . Maine NPS Program Mission
, Goals and Guiding Principles

Maine’s NPS Program is guided by the following mission, goals and guiding principles. Section X
of this Plan lists objectives, actions and milestones that will be used to achieve program goals to
address Maine’s priority NPS problems.



### Long

- term Goal s The long term goals of Maine’s NPS program are:

 Restor ation of Waters

- To restore water bodies that are impaired by nonpoint sources so that they meet water quality standard s.

 Protection of Waters

- To prevent NPS

- related impairments of unimpaired water bodies.



### Guiding Principles Maine’s lead NPS agencies will use the following six guiding principles to help implement strategies to achieve NPS manage ment program goals and objectives (Figure 1) :

1. Promote the use of state

- agency defined "best manageme nt practice guidelines" (BMPs) throughout the entire state t o control nonpoint so urces ;

2. Promote voluntary, locally

- led, incentive

- based strategies to address NPS issues

3. Ensure informed compliance with applicable regulatory requirements;

4. Establish and strengthen partnerships among stakeholders at local, state

, and federal levels in the management of NPS polluti on sources;

5. Encourage proper management of wetlands, riparian corridors, floodplains, natural areas

, and other green infrastructure resources in urban and rural watersheds to help restore or maintain healthy watersheds; and Maine's NPS Program Mission:
Maine’s lead NPS agencies (Department of Environmental Protection, Department of Agriculture, Conservation and Forestry, Department of Transportation, Department of Health and Human Services) administer programs to help prevent, control, or abate water pollution caused by nonpoint sources so that waters attain or exceed their classification standards and beneficial uses of water resources are maintained or restored.Maine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

3 6. Use a watershed

- based management approach as a coordinating framework to organize public and private sector efforts to identify, prioritize, and impl ement activities to address NPS problems to restore NPS impaired waters or protect waters threatened by NPS pollution.

## III. Maine NPS Management Program Framework

A s Maine’s lead water quality agency

, DEP is responsible f o r develop ing and implement ing water quality protection and im provement programs required under state and federal laws. DEP manag es both regulatory and voluntary programs and collaborates with local, state

, and federal agencies to plan and implement strategies to protect Maine’s water quality. The following section summari zes key State and Federal laws that guide Maine’s NPS program and
Maine’s overall approach to control ling NPS pollution.



## A. Key State and Federal Laws

Three laws helped prompt the establishment and formalization of Maine ’s NPS program. These laws provide ongoing structure and guidance for the program and identify the agencies involved in program implementation

.

Maine's NPS P ollution P rogram S tatute In 1991, Maine’s Nonpoint Source Pollution Program was codified under State s tatute (38

M

. R

. S . Chapter 3, Subchapter 1, Article 1

- F) . The statute directs S tate agencies to promote the
use of S tate agency

- defined "best management practice guidelines" (BMPs) to prevent or reduce water pollution from nonpoint sources. DEP administers the State of Maine NPS

program and coordinates their effor ts with other state agencies. U nder Maine’s statute, DEP,

t he Department of Agriculture, Conservation, and Forestry (DACF), and the Department o f Transportation ( Maine DOT) are responsible f o r de veloping and promot ing the use of BMP s in
order to redu ce and prevent NPS pollution from their associated pollution categories : Development ( DEP ); Transportation ( Maine DOT); Agriculture (DACF) and Forestry (DACF).

Section 319 of the F ederal Clean Water Act Congress enacted Section 319 of the Clean Water Act in 1987 and thereby established a national program to control nonpoint sources of water pollution. Funding appropriated under §319 can be used to implement stat e NPS programs including, as appropriate, non

- regulatory or regulatory programs for enforcement, technical assistance, financial assistance, education, training, technology transfer, and demonstration projects to achieve implementation of best
management p ractices and to meet water quality goals. EPA provides grants to states, tribes, and territories to implement programs that control and prevent nonpoint source pollution to

waters. To be eligible for §319 funding

, states must implement updated NPS Manage ment Programs and follow other program guidelines ( EPA, 2013 )

.

Section 6217 of the F ederal Coastal Zone Act Reauthorization Amendments (CZARA)
EPA and the National Oceanic and Atmospheric Administration (NOAA) jointly administer a

program that establishes management measures designed to control runoff from six main sources: forestry

, agriculture

, urban areas

, marinas

, hydrologic modification and riparian areas. These measures are backed by enforceable state policies and actions (“s tate authoriti es ”) that will ensure implementation of the program. All coastal and Grea t Lakes states and territoriesMaine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

5 that participate in the Coastal Zone Management Program are required to develop coastal NPS control programs. In 2003 EPA and NOAA jointly approved th e Maine Coastal NPS Pollution Control Program

, which implements management measures in the whole state including the
coastal zone

.



## B. Statewide and Watershed

- based Approaches

Maine ’s NPS program uses a combination of statewide programs and targeted watershed projects to achieve its long term goals of restoring and protecting waters.

Statewide Approach Maine’s statewide approach targets six major categories of NPS pollution identified in the state. These NPS pollution categories include developed areas, agriculture, transportation, forestry, onsite wastewater disposa l systems and hydrologic modification. The S tate’s lead NPS agencies and other cooperating agencies and partners implement an array of regulatory and non

regulatory programs to control pollution from these major NPS categories.

Regulatory programs (e.g., permitting, compliance assistance and enforcement) are
administered under several core State of Maine environmental law s including but not limited to the Storm Water Management Law; the Site Location of Development Law; the Erosion and Sedimentation Control Law; the Natural Resources Protection Act (NRPA) ; the Mandatory Shoreland Zoning Act; the Subsurface Wastewater Disposal Rules; Pesticide Control l aws; the Nutrient Management Act; and the Forest Practices Act. These laws limit specific activities (e.g., soil disturbance, timber cutting and pesticide application) and require the use of BMPs to limit pollution transport to waterbodies. A number of t hese laws, including the Stormwater Management Law and NRPA, also provide enforceable policies of the Maine Coastal Program and are applicable to federal agency actions under the CZMA’s consistency provision. Section

VII in the Plan outlines how these cor e state environmental laws may apply to various NPS categories.

NPS pollution is oftentimes not adequately addressed by existing laws. As such, e fforts to encourage more widespread voluntary use of BMPs are a vital component of Maine’s NPS Program. Non

- regulatory programs often involve providing technical assistance, BMP training, and outreach to municipalities, individuals, businesses, and non

- governmental organizations. Recognition programs and demonstration projects are also used to recognize individ uals and businesses and highlight projects that implement BMPs to prevent or reduce NPS pollution.

Watershed

- based Approach In addition to statewide programs, Maine also uses a targeted watershed approach to restore and protect waters. Through a priorit y

- setting process, DEP first identifies watersheds that are most in need of improved NPS control efforts and where there is considerable opportunity to make substantial progress restor ing or protecting a waterbody . Projects in these NPS Priority
Watershed s typically follow four steps as they move towards the restoration or protection goals. Steps include conducting targeted assessment and stressor analysis; develop ing locally

.

Partnerships and I ntegration with Other Programs Success of the NPS program depends on maintain ing existing and forg ing new partnerships with

state

, interstate

, tribal

, regional and local entities ; private sector groups ; citizens groups ; and
fe deral agenci es. These partners and their affiliated programs have goals that align or overlap with the goals of the NPS Program, thus provid ing mutual benefits. Partnerships strengthen the program by attrac ting new ideas and input, increasing understanding of NPS problems

, and building commitment to implementing solutions. Maine’s lead NPS agencies use a variety of formal and informal means to develop and maintain these partnerships. Refer to Section VI II for information about partnerships.

### Assessed Marine Waters (acres) 

## C. Restoring Impaired Waters and Protecting Unimpaired Waters Threatened by NPS

This plan outlines approach es to both restore the relatively small number of waters impaired by NPS pollution and protect the many unimpaired waters
threatened by NPS pollution. Maine’s 2012 In tegrated Report (IR) indicate s that state ’s waters are very clean with 96 % of assessed river and stream miles, 9 4 % of marine waters and 91 % of lake acres fully attain ing water quality standards (Figure 3)

. C orrespondingly

, only 4 % of

asse ssed river and stream miles, 6 % of marine waters and 9 % of lake acres were listed as impaired. That said, many of Maine’s clean waters that attain standards are threatened due to NPS sources. For example, 24 lakes (3.7 % of lake acres) are impaired due to nutrients, but 215 lakes (11 % of lake acres) are threatened

, primarily by nutrients, by existing developed areas and projected growth rates in their watersheds. These 215 lakes are designated “Most at Risk”
under Maine’s Storm W ater Law.

Given the relatively high pr oportion of unimpaired waters and relatively low number of impaired waters in Maine, DEP prioritizes and balances the use of available NPS resources to protect and restore lakes, streams and marine waters. Prevention of water pollution is a daunting challenge for watersheds facing increased development pressures . Since prevention is far more feasible and less expensive than restoration of an already impaired waterbody, DEP
allocate s significant pr ogram resources for projects that help communities protect waters
consi dered threatened or most at risk. The NPS Priority W atersheds list (Appendix 2 ) identifies impaired waters and unimpaired waters threatened by NPS pollution.

## Maine's Landscape IV. Maine’s Water Resources

Maine is the largest state in New England with a total surface area of over 35,000 square miles (Table 1)

. The state has an abundance of fresh

water resources with the large r surface waters

occup ying nearly 4,500 square miles (Table 2)

. Maine’s 5,780 lakes and ponds cover 986,952 acres, an area larger than the State of Rhode Island. There are over 7,000 perennial brooks,

streams

, and rivers that extend nearly 55,000
miles

. Fresh and salt water wetlands cover an additional 5,196 square miles. Groundwater is considered plentiful with three basic types of aquifers ( stratified drift deposits , till, and
fractured bedrock ) . Stratified drift deposits , which provide large

- volume water supply wells

cover about 10% of the state , and bedrock aquif ers underlie the entire state

. Maine ’s coastline is 2,757 miles long

. The re is a total area 2,846 square miles of m arine waters out to the "three
mile" limit, including near shore waters and tidal r ivers

## A. Summary of Waters Impaired by NPS Pollution

Maine’s 2012 Integrated Report (IR) lists lakes, rivers, streams and marine waters impaired by point and /or nonpoint pollution sources . The cause of impairment is variable and site specific. All freshwaters in Maine are under a fish consumption advisory due to impairment caused by atmospheric deposition of mercury. At mospheric deposition is the largest single source of

mercury polluti on. All marine waters are impaired for p olychlorinated b iphenyls (PCBs) and
dioxins and fall under a statewide lobster tomalley consumption advisory. Also, b acterial contamination is a significant cause of impairment, affecting 159 square miles of marine waters (not including CSO affected waters).

The relative importance of pollution sources in different types of impaired waters varies considerably . O nly one lake is impaired by a point source (Figure 5). Most lakes are affected by
a mix of rural residen tial development, agriculture, internal recycling and urban stormwater. In streams, i ndustrial point source discharges, unknown sour ces and NPS are of almost equal importance, each affecting approximately 400 river miles , and g eneral agricultural NPS sour ces affect 358 miles (Figure 6). M unicipal point source discharges, combined sewer overflows,

, and biological characteristics associated with the state's water classification program. As established in Maine statute (38 M

. R

. S

. Sections 464

- 470), the classification program consists of three components: designated uses (e.g. drinking water supply, recreation in and on the water, habitat for fish and other aquatic life); criteria (e.g. bacteria, dissolved oxygen and biological criteria); and an anti

degradation statement (e.g. natural, free flowing) that specify levels of water quality necessary to maintain the designated uses.

2 T he square miles, miles, or acreage attributed to causes and sources in these figures may be l isted more than once if a waterbody is subjected to several different types of disturbance. For example if a waterbody has both agricultural and NPS sources of impairment, the impaired acreage or miles will be listed in both the Agriculture and NPS categor ies. For more information on source categories, see the Maine Integrated Report. 163 154

12 All State waters have a classification assignment (Lakes: GPA. Rivers and streams: AA, A, B, C. Marine and estuarine: SA, S B, SC). Wetlands are classified the same as their associated surface

waters. W etlands that are part of great ponds or natural lakes and ponds less than 10 acres in

size are GPA waters . A ll freshwater wetlands not classified as GPA waters are class AA, A, B or C under Sections 467 and 468 according to the watershed in which they occur. Coastal wetlands are classified SA, SB or SC according to the provisions of Section 469 (Classification o f Estuarine and Marine Waters).

Groundwater is classified by its suitability for drinking water purposes. Under the Maine Water Classification Program Section 465

- B, groundwater is classified as either potable (GW

- A) or unpotable (GW

- B). Water is unpota ble when the concentrations of chemical compounds detected exceed either the Maximum Contaminant Levels (MCL) or the Maximum Exposure Guidelines (MEG) as defined in the Rules Relating to Drinking Water administered by the Maine Department of Health and Hum an Services (DHHS). Although there are localities where groundwa ter is unpotable and contaminated, no groundwater is cur rently classified GW

- B.

The DEP is responsible for overall assessment of the State’s waters. W ith support from
partners, DEP bienn iall y produces the Integrated Water M onitoring and Assessment Report that fulfills Clean Water Act reporting requirements under Section 305(b), Section 303(d) (list of impaired waters) and Section 314 (Clean Lakes Report). This report provides a summary of th e current status of the State’s waters and identifies impaired waters that are not meeting one or more of their designated uses

. The Integrated Report lists waters in one of five categories of

attainment ( Figure 8).

Figure 8. Maine’s Water Quality C ategories of Attainment (Maine DEP , 2012).

## C. TMDL Assessment Reports and TMDL Implementation

DEP monitors the water quality conditions of Maine's rivers, lakes, and marine waters to determine if they meet designated uses for recreation, swimming, fishing, shellfish harvesting, and drinking water supply, and if the waters support healthy habitats f or fish and wildlife. DEP places degraded waters (i.e. not attaining water quality standards needed to support designated uses) on the list of impaired waters, or the Section 303(d) list. A Total Maximum Daily Load (TMDL) assessment is required for nonatt ainment waters under state and federal water quality laws to determine the reductions needed from point and nonpoint pollution
sources to meet standards. The fundamental goal of a TMDL assessment is to establish water pollution control targets and recomme nd actions needed for planning and implementation
work

.
Communities, agencies, and individuals are invited to provide input on the development of TMDLs. After TMDL assessments are completed, local stakeholders often consult TMDLs as they take action to apply conservation practices (BMPs) to eliminate or reduce NPS pollution

sources. DEP’s staff involved with TMDLs provides limited technical assistance to assist

communities to further scope out and identify problems.

Stormwater runoff from both point a nd nonpoint source s have long been recognized as a significant source of pollutants to surface waters. Historically, individual programs have been developed to address specific aspects of stormwater control. One such aspect is TMDL development. TMDLs ty pically cover one pollutant at a time and do not take into account the other various programs that may impact stormwater runoff. While there may be several programs focusing on a specific location/waterbody, often coordination of activities is limited.

DE P will improve coordination of all stormwater related programs to make progress restoring waters impaired by point or nonpoint sources through a Watershed Improvement Process (WIP). The WIP is designed to involve and coordinate all programmatic aspects of the DEP that deal with stormwater. Examples of these are the MS4 permitting program, watershed assessments, Site Law requirements (Chap 500), SRF loans, 319 grants, etc. Further, the scope of the WIP is designed to involve other agencies/organizations t hat have stormwater impacts as well, such as MaineDOT, MTA, DACF, DMR, SWCDs, and NRCS.

DEP will apply the watershed

- based approach, described in Section IV, when it is appropriate to help ensure effective coordination of stormwater runoff control activiti es to restore impaired

waters.Maine NPS Management Program Plan 2015

## V. Statewide Watershed Prioritization

Given Maine’s extensive water resources, statewide watershed prioritization is a n important
part of Maine’s NPS program. Maine’s first NPS p riority w atersheds l ist was developed in 19 8 9 and substantially revised in 199 8

. The l ist was updated as part of development of this NPS

m anagement p lan. NPS impaired or threatened 3 waters with significant regional or statewide value were placed on the list. The list was developed to help pr ioritize DEP NPS water pollution control efforts and attract local communities to take action to restore or protect waters impaired or threatened by NPS pollution. DEP plans to review and update the NPS Priority

Water sheds list on a regular basis, and c han ges are anticipated as prioritization criteria are refined (e.g., EPA Recovery Potential Screening Tool for streams) and new evaluation techniques (e.g., aluminum content in lake sediment) become available.

In addition to this listing process

, DEP staff also conducts an annual review of NPS p riority

w atersheds and identifies a small subset of highest priority waters

. This annual review helps DEP direct NPS program funds and services to address compelling needs and opportunities to make progress restoring or protecting waters

. Selection criteria and some of the tools available
for targeted action s are described later in this section.



## A. NPS Priority Watersheds List

The purpose of the NPS priority watersheds list is to encou rage NPS abatement work in
watersheds most vulnerable to NPS pollution. The list is used to help prioritize DEP NPS water pollution control efforts and attract local communities to take action to restore or protect waters impaired or threatened by NPS poll ution. The 199 8 NPS priority w atersheds l ist was updated as par t of development of this NPS p lan. Watersheds were evaluated using several guiding principles. The first principle wa s NPS priority waters must have NPS pollution as the primary s ource of impa irment or threat. Watersheds with point sources or legacy pollutants as the primary source of pollution were not selected as priorities since the point source or legacy pollutant would have to be addressed for water quality to significantly improve. Secon d, watersheds were evaluated for the likelihood that NPS grant funds and support could make a difference in the water qua lity. Third, the number of NPS priority watersheds was kept reasonably focused so that resources can be invested where they are most n eeded and there is opportunity to effectively restore or protect waters vulnerable to NPS pollution.

Prioritization criteria were developed to make selections as objective as possible, using monitoring data, analysis, and reports. To determine the waterb ody

15 statewide lake, stream, or marine water quality and management issues reviewed available waterbody data and information. Priority lists and knowledge from partner agencies and regional monitoring organizations were consulted. Waterbody

- specific prioritization criteria
are summarized below and d escribed in detail in Appendix 2

.

In addition to the NPS Priority Watersheds List, there are several other lists that help guide
MDEP efforts and r egulatory programs. This includes impaired waters

, waters with approved TMDLs, Chapter 502 Lakes Most at Risk from New Development, and Urban Impaired Streams.
These lists were used to help develop p r ioritization criteria for NPS P riority W atersheds List.

Lake Watersheds Impaired lakes were assessed as to whether reducing nonpoint sources would be likely to improve water quality over the long term. Lakes meeting water quality standards were assessed on threats to water quality and value of the resource. Threatened lakes included lakes with a significant negative trend in water clarity, sensitivity to additional phosphorus inputs, or recent increased
threat to the watershed by development or agriculture. Lakes on the DEP Watch List were also
considered threatened 4 . High value lakes included public drinking water supplies, designated priorities by a partner agency, or lakes with outstanding water quality in need o f protecti on. Over 2600 lakes
were consider ed in the evaluation process. Twenty

- one impaired lakes and 14 7 unimpaired lakes were selected for inclusion on the priority list.

Stream Watersheds A NPS impaired stream watershed was added to the priority list if it had a TMDL, was identified as a priority watershed by a partner agency or organization, or was assessed as having a high risk of future development due to its proximity to a highway exit. An unimpaired stream watershed was added to the priority list if it met any of the criteria listed for the priority impaired streams, if it was on the DEP Watch List, or if recent increased impacts or significant potential threats from agriculture or

16 dev elopment were evident. Seventy o ne (71) impaired streams and 7 7 threatened streams were placed on the priority list.

Marine Watersheds Impaired and threatened marine waters were assessed by the same criteria. A watershed was added to the priority list if likely NPS sources were known and tied to shellfish harvest area closures. Watersheds were also added to the priority list if partner organizations had documented water quality indicators linked to NPS pollution, or if the waters were threatened by lo cal agriculture, streams, or development that drains to public beaches or protected embayments. Additions to the marine priority list are anticipated as more information
becomes available. Eleven impaired marine waters and 1 6 threatened marine waters wer e included on the priority list.



## B. DEP Targeted Watersheds

DEP conducts an annual evaluation that assigns elevated priority to a small subset of waters on the NPS Priority Watersheds List

. DEP then i dentifies ways to focus staff or financial resources

on restoration or protection efforts in these watersheds

.

Criteria used to select DEP’s targeted watersheds include those used to generate the NPS Priority Watersheds List as well as more strategic factors

. Targeted watersheds have typically
include d impaired waters that DEP sees as having a high restoration potential based on water quality monitoring data and watershed needs . Targeted efforts also capitalize on strong local interest and support, leverage other available funding sources , jump

- start ne w watershed efforts, prompt continued momentum on established projects and/or protect against an

imminent NPS threat.

After a subset of priority waters is established, DEP con sid ers and select appropriate tools, such

as , NPS grants or staff services to prompt and complete additional protection or restoration work in these targeted watersheds. DEP may use a request for proposals (RFP) process to provide grants for projects in targeted watersheds. In addition, DEP may p rovide extra staff
support in target ed watersheds. For example, DEP staff can conduct water quality monitoring and stormwater catchment mapping in an urban impaired stream to supplement an upcoming
watershed

- based planning effort in a targeted watershed. This investment of staff time leads to a better understanding of watershed stressors and needs and sets the stage for more
effective watershed restoration efforts.

This internal prioritization process has been used on an informal basis for many years. DEP has provided direct

- f unding and conducted water quality monitoring and catchment mapping in

numerous watersheds. Moving ahead, DEP will conduct the evaluation and provide a list of the targeted watersheds to EPA and partners.Maine NPS Management Program Plan 2015

## V I . Maine Watershed

- based Approach

The watershed

- based approach is a coordinating framework for identifying, prioritizing, and fixing water quality problems. This approach seeks to organize both public and private sector efforts within a specified geographic area. The watershed

- based appr oach allows the DEP to focus resources on the waterbodie s and watersheds most in need and to follow a systematic approach to meet water quality goals. There are four steps to this approach:

Figure 9. Maine DEP’s Watershed

- b ased Approach Steps

.

 Targeted Assessment and Stressor Analysis

- Once DEP or local groups focus attention on a priority water, it is critical to gather the information necessary to accurately characterize
the NPS impairments a nd/or threats

. Water quality monitoring, watershed surveys and
other wa tershed information should be evaluated to determine the principal stressors and

NPS sources that contribute to the impairment or threat.

 Watershed

- based Plan Development

– S takeholders produce a locally

- supported
watershed

- based plan (WBP) that describes actions needed for NPS mitigation and water quality protection or restoration. To be eligible for Section 319 funding, plans must include specific element s required by EPA and DEP.

 Watershed

- based Plan Implementation

- Plan implementation is usually coordinated by a local entity such as a municipality, Soil and Water Conservation District, or a local watershed

group. I mplementation usually involve s a number of phased projects and is typically funded by a mix of grants a nd local sources

.

 Measuring Success and Monitoring Environmental Results

- In addition to implementing
the NPS pollution reduction measures identified in the plan, implementation will include ongoing or periodic evaluation to assess whether the plan is meeting its goals and objectives

.Maine NPS Management Program Plan 2015

18 Abbreviated Watershed Approaches

Some watershed restoration and protection efforts may not incorporate al l of the steps outlined in this section . There is usually some element of assessment involved, but the planning process may be largely skipped, often because solutions are straight

forward and local groups plan to implement BMPs independently

. Some examples follow:

 The source identification and fixes required to address a
localized bacteria impairment may be quite simple

, and elimination of the impairment may be accomplished with out the development of a plan. S imply bringing the problem to the
attention of the local sewer district or code en forcement officer would likely result in fixing the problem

.

 Lake watershed surveys are often done informally and funded locally. They provide information to guide loca l efforts to
address sources.

 BMP i mplementation work is also often done without formal planning. Municipalities may use local revenues or mitigation funds to address obvious pollutant sources. Locally supported
Youth Conservation C orps (YCC) often provide the labor to implement BMPs in l ake watersheds. Sometimes this is part of watershed based plan implementation, but often it proceeds independently due to local interest in water quality protection

.



## A

. Targeted Assessment and Stressor Analysis

The success of restoration and protection efforts hinges on understanding the principal environmental stressors connected to the water quality impairment or potential impairment
and the watershed conditions associated with those stressors. The types and extent of
assessment and stressor identifi cation needed for a given watershed varies depending on the type of waterbody and available existing information. See Appendix 4 for more detailed information about this step.

For m ost lakes on the NPS Priority Watersheds list, t here is a long record of water quality data
and an understanding that phosphorus loading is the primary environmental stressor. As a result, this step primarily involves identifying phosphorus sources to the lake and opportunities
to reduce these sources. Water shed surveys a re the most commonly used tools used to meet these needs

. Over 120 surveys have been completed over the past 20 years, and the methodology is documented in the DEP’s Citizen’s Guide to Volunteer Lake Watershed Surveys (2012). During a waters hed survey, DEP and other partners train local volunteers to document Local BMP implementation

- planting a rain garden.

YCC at work.Maine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

19 phosphorus sources ( primarily in th e form of soil erosion problems), develop recommendations to mitigate the sources, and rate the cost and priority of the sites. The resulting survey r eport and prioritized list of watershed problems can then be used to develop watershed

- based plans and guide implementation efforts.

Environmental stressors are often more challenging to identify in stream watersheds . This is particularly true in urban s treams where there can be several stressors

, and they can change throughout the stream network. Stressors in a stream could include chloride, stream channel alterations, nutrient loading, legacy pollutants, poor instream habitat, riparian buffer
disturban ce and flow problems. Once the stressor(s) are pinpointed

, specific sources must then be identified to help mitigate the impacts of the stressors. Targeted assessment usually
includes a combination of water quality screening , biological assessments, stre am habitat and
corridor assessments and watershed assessments.

B acteria are often the primary concern and stressor in marine waters. However, identification of bacteria sources is often quite challenging. There ar e several tools available to identify and prioritize potential bacteria sources including water quality monitoring, DMR sanitary surveys

, smoke and dye testing

, and canine detection of human bacteria sources.



## B. Watershed

- based Plan Development

Effect ive planning is needed to guide successful watershed restoration and protection efforts. In general, a watershed plan describes actions needed to restore a waterbody that is impaired by NPS pollution or to protect unimpaired waters threatened by NPS pollution. An effective pl an identifies and prioritizes the structural and non

- structural practices necessary to address
the environmental stressors and sources of NPS pollution that contribute to or threaten impairment of the water body. It identifies stakeholders and partners wh o can work on projects; pollutant reduction goals; cost estimates and strategies for funding plan implementation; and ways to measure results and water quality improvements.

Key Components of Successful Plans
Plans should be developed for a geographically

- appropriate scale so that the planned implementation efforts can lead to measurable reductions in pollution and the achievement of water quality goals. Plans should reference an area large enough to address all th e major sources and causes of impairments and threats to the water body of concern. However, the area should not be so large that chances of successful implementation are not feasible or practical. Several parts of the planning process are particularly important in development of
effective watershed

- based plans.

 Stakeholder Involvement

- There will be little support for implementation of a watershed based plan if the planning process does not include as many of those individuals and organizations that will have a role in plan implementation as possible . Every effort should be made to involve key landowners, municipal officials, representatives from relevant stateMaine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

20 agencies (e.g. Transportation, Agriculture), local resource and conservation groups, and local experts (e.g. engineering consultants, planners, realtors). An effective way to enhance involvement is by recruiting these people for the planning project steering committee and, in watersheds with complex issues, for the subcommittees (e.g. technic al advisory, education and outreach, ordinance development) where most of the decisions are made. Strong local participation leads to local buy

- in , which is essential for successful plan implementation.

 Clear Definition of Plan O bjectives

- Early in the plan development process, the steering committee should come to agreement on the water quality, ecological and community related objectives that the plan will seek to achieve. In some instances, these will be dictated by state water quality standards, but other objectives may also be identified. Failure to come to agreement on the goals of the plan will make the process of plan development inefficient and unnecessarily difficult.

 Financing

- For some watersheds the pollutant loading and other plan goals might be
achieved with installation of a modest number of low

- cost BMPs. In these watersheds, existing local resources and available grants might be able to achieve the plan goals in a ten year period. More commonly, plans for impaired waterbodies (e.g., urban streams or high ly agricultural watersheds) involve numerous and expensive BMPs that exceed existing funding resources. In such cases, planning pr ojects need to consider other possible funding mechanisms (e.g.

, stormwa ter utilities, local bonds ). Local involvement in this financial discussion is critical to ensure future public support of selected funding avenues.

21 EPA Nine

- Element Plans Starting in 200 3 , EPA required a specific type of plan to guide Section 319

- funded work in impaired watersheds. These EPA plans are referred to as
watershed

- based plans or ‘nine

- element’ plans because they must address nin e key elements:

 An identification of the causes and sources that
will need to be controlled to achieve the load reductions and goals in the plan;

 An estimate of the load reductions expected for the management measures in the plan;

 A description of the NPS management measures that will need to be implemented to achieve the
load reductions estimated and an identification of
the critical areas in which those measures will be needed to implemented;

 An estimate of the amounts of technical and financial assistan ce needed , associated costs, and/or the sources and authorities that will be relied upon to implement the plan;

 An information and education component that will be used to enhance public understanding of the project;

 A schedule for implementing the NPS man agement measures;

 A description of interim, measurable milestones for determining whether NPS management measures or other control actions are being implemented;

 A set of criteria that can be used to determine whether loading reductions are being achieved over time and that substantial progress is being made towards water quality standards; and

 A monitoring component to evaluate the effectiveness of the implementation efforts

To date the DEP has accepted 30 nine

- element plans ( Table 3 ). Of these, 2 7 plans are for impaired watersheds and three plans for threatened waters. Two of the three unimpaired
waters with nine

- element plans were listed as impaired when they were developed and have since been restored. There are 16 plans for inland streams; 11 plans are for lakes; and t hree plans for coastal streams. Capisic Brook Nine

22 Lake Watershed

- based Protection Plans

EPA NPS Program Guidelines (2013) recognized several cases where alternatives to nine

element plans may provide an effective approach toward achieving the water quality goals of

Section 319

- funded restoration or protection efforts. EPA outlined the elements required in alternative plans a nd the circumstances under which alternative plans may be accepted, including those pertaining to the protection of high quality and/or unimpaired waters.

DEP used the EPA guidelines as a basis to develop guidance for lake watershed

- b ased protection plans in Maine ( Guidance for Maine Lake Watershed

- b ased Protection Plans (2013 ))

. Most, if not all, watershed plans for unimpaired waters are expected to follow this guidance,
instead of the more intensive nine

- element planning guidelines required for impaired waters. A recent NPS watershed survey (or equivalent assessment) must be in place before a lake
watershed

- based protection plan can be developed. This information is a key component of an alternative plan. If the watershed survey is outdated, there is an increased likelihood that the survey is no longer accurate. As such, lakes with surveys over five years old should not complete alternative plans until the survey data are validated or updated. To date, DEP has accepted s even Lake Watershed

- based Protection Plans ( Table 4 ).

23 Other Types of Alternative Plans In addition to alternative plans for high quality or unimpaired waters, the EPA guid elines (2013)
list three other situations where alternative plans may be warranted. This includes when the impairment is not specific to a pollutant. Nine

- element plans emphasize identifying major NPS pollutant sources and ways to achieve load reduction. However, this is not po ssible if the impairment is not caused by a pollutant but by a water quality problem such as a dam and concomitant altered flow regimes. EPA may also find an alternative plan acceptable when
there is a need to respond to a NPS pollution emergency o r urgent NPS public health risk (e.g., to reduce pollution affecting drinking water safety). In Maine no such plans have been developed to date. However, DEP will work with partners and EPA to help guide development of such alternative plans if the need arises.

EPA may also find alternative plans acceptable in cases where a small

- scale water quality impairment results from a few sources that are not caused by larger watershed

- wide problems and can be fully addressed within one grant period. EPA (2013) stated: “In meeting these conditions, the state will ensure that multiple smaller problems are not dealt with in a piecemeal fashion when they are actually part of a larger water quality problem involving multiple pollution sources in the watershed.” In Ma ine

, most NPS impairments occur from multiple sources within a watershed.



## C . Watershed

- based Plan Implementation

The next step of the watershed

- based approach is to implement the watershed based plan (WBP) and actions
that ultimately protect and/or restore the waterbody. WBPs are implemented by local entities such as municipalities , Soil and Water Conservation Districts or local associations. Plan implementation consist s of a suite of actions described in the watershed

- based plans. Actions may include getting ordinances passed, having the public works department install BMPs, retrofitting or installing structural stormwate r BMPs, restoring rip arian and aquatic habitat and implem enting public outreach

programs

. P lan implementation usually takes place through a series of phased projects over period of ten or

more year s

.

Typical funding sources for implementation are from th e municipality, Section 319 and other federal funds, private grants, lake associations, and in certain cases stormwater utilities. In instances where the source reduction and prevention measures are relatively simple, there is community support, and the c ost is low, plans may be substantially implemented with financial support from grant programs, most often thro ugh EPA Section 319 grants. Plans aimed at protecting threatened lakes often fall into this category. When the measures identified in the plan a re more complex and expensive (e.g., restorati on of an impaired urban stream), funding Watershed

- based plan implementation

- installation of
bioretention swale.Maine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

24 mechanisms will likely need to be more diverse and include some level of local financial support such as a stormwater utility. In either case , plan implementation is li kely to involve a number of phased projects. It may also involve the establishment of a local authority such as a watershed management district or a stormwater utility district to implement the plan over an extended period.

Streams In recent years, most of the NPS implementation work in stream watersheds has focused on impaired strea ms. This includes rural streams impaired by agricultural sources and urban impaired streams. Restoration work in rural stream watersheds usually includes strong
involve ment from local farmers, the Soil and Water Conservation District and NRCS and includes construction of agricultural BMPs on a small number of farms

. NRCS funding is also often leveraged to stretch resources and get more work done on the ground. Since 20 13, the National Water Quality Initiative (NWQI) partnership between DEP, EPA and NRCS has also helped focus resources on three watersheds in Maine. This includes the Unity Pond watershed and portions of the Meduxnekeag River and Sebasticook Lake watershe ds.

Restoration work in urban streams tends to include a diverse set of actions and partners. M unicipalities typically start plan implementation with ‘the low hanging fruit,’ such as easy fixes on municipal properties
and on outreach efforts. Larger more expensive aspects of the plan (e.g., major structural retrofits, ordinance implementation, and crea tion of stormwater u tilities) are often phased in over time as funding sources and political support are secured. This has been done by reaching out to the planning board and elected officials, and incorporating relevant portions of WBP into the municipality’s comprehensive plan. R estoration of
urban stream s may take decades and up to millions of dollars due to the complexities of multiple pollution
sources and fixes.

Lakes Lake WBP implementation is usually less complex than urban stream implementation because phosphorus is often the only pollutant of concern. Implementation usually consist of BMP installations at eroding sites and/or agricultural properties, changes in ordinances, creation of or continued support of a Youth Conservation Corps, and out reach. While municipalities are also involved in lake
watershed

- based plan, often the local lake association takes a leadership role and provides fuel for political support and action. The time period of implementation can range from five years
to decade s, depending on the size of the watershed and amount and types of phosphorus DEP support assessing an urban impaired stream. (Photo by FBE)Maine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

25 sources. If the lake has an internal phosphorus recycling problem, implementation may also include efforts, such as treatment with aluminum salts to prevent release from the sedi ments.

Marine Water s Implementation efforts in marine waters have been limited to a relatively small number of watersheds in recent years . However, interest in coastal NPS work has be en increasing, particularly in s outhern Maine. The Maine Healthy Beach es (MHB) program works with
communities to monitor bacteria levels at 29 beach areas. NPS has been identified as a probable pollution source in many of these areas with high bacteria levels. Several coastal communities regulated through the Municipal Sep arate Storm Sewers Systems (MS4) program have also targeted coastal stream watersheds for the stormwater abatement work required through their MS4 permits. Although i mplementation work funded through 319 grants cannot be used to complete MS4 permit requir ements; it can complement their efforts to address stormwater and bacteria impacts.

DEP Support DEP promotes and supports implementation of WBPs largely through DEP technical services
and EPA Section 319 grants

- four percent ($752,292) of Section 319 f unds received by

DEP in FFY 2013 ($1,726,692) were used for implementation of WBP s. DEP provides t echnical

assistance to : assist municipalities or watershed groups design and install structural BMPs;
share lessons learned from other implement ation projects; provide information to planning boards; and provide ot her resources as needed. Since implementation of WBPs is led by local entities, DEP’s support is flexible and responsive to local needs. This assistance may be
intensive and short

, or spread

- out over many phases, whichever is mo re appropriate and supportive of local plan implementation.



## D

. Measuring Success and Monitoring Environmental Results

Updating Watershed Plans Restoration and protection of Maine’s waters is an ongoing process (Figure 10) . Restoration of impaired waters can take years or even decades, and protection work is never done. As such, watershed plans all become outdated over time. Plans should be periodically evaluated and updated so they remain relevant and useful. DEP has not yet developed a process to prompt partners to update their watershed plans or request updated plans or status reports of progress on plan implementation. This need is addressed NPS Plan’s five year objectives.

As a WBP is implemented , new issues may be identified and alternative strategies may become available. The plan will need to be amended to address these new concerns and opportunities. Similarly, progress on the plan needs to be monitored and changes in the timeline and
milest ones need to be incorporated. The implementing entity should be responsible for amendments and updates to the plan. Since WPBs for urban streams are relatively new, they have not undergone major updates. Updates of lake watershed plans and watershed sur veys don’t have a set update schedule. Local interest in lake protection and motivation to work on water quality fluctuates, so plans will be updated as local interest in lake protection is renewed.Maine NPS Management Program Plan 2015

Environmental Monitoring
Watershed

- based plans include a monitoring component to assess progress toward the plan’s restoration or protection goals. This monitoring component typically involves estimating pollutant loading reductions and conducting water quality monitoring to track progress over

time. Some of this work can be conducted by l ocal stakeholders

, and the resulting information

can used to assess incremental progress over time. For example, Trout Brook ’s monitoring efforts include water quality monitoring to look improvements following the mitigation of a
chloride source to the st ream. In addition, biomonitoring using kicknet methods are being
conducted by local volunteers to determine if the stream’s macroinvertebrate population is improving as BMPs are installed in the watershed

. L ocal groups also rely on DEP’s monitoring

progr ams to assess water quality conditions and report on the official a ttainment status. See

Section X I for more detailed information on monitoring environmental success.Maine NPS Management Program Plan 2015

. Statewide NPS Cont rol Strategies by NPS Category

Section 319 of the C lean Water Act requires each state to identify major NPS categories or subcategories and identify BMPs that may be used to reduce pollutant loadings for each. This NPS plan designates and describes six major NPS categories: Agriculture, Developed Areas, Transportat ion, Forestry, Onsi te Wastewater Disposal Systems and Hydrologic Modification. In addition, two other NPS categories (boatyards/ marinas and land disposal) addressed primarily through regulatory programs are described later in this section

This section d escribes the s ix major NPS categories in the Maine NPS Management Program and provides descrip tions of management strategies, core law/regulatory authority, NPS pollution sources, BMP guidelines, and p rog rams and p rojects. Refer to Section X for tables listing NPS Program f ive

## A. Developed Areas

Lead Agency: Maine Department of Environmental Protection (DEP)

Management Strategies Encourage use of erosion and sediment controls and stormwater management BMPs through administration of land use laws and promotion of voluntary measures . Strategies
include continue to administer the Storm Water Management Law and Site Location of Development Laws; ensure stormwater and ESC BMPs are in place and b eing maintained on permitted development sites; continue updating the Stormwater BMP Manual to include latest technology options for stormwater treatment; and continue training of town officials, engineers, developers on ways to reduce NPS impacts.

C ore Law / Regulatory Authority DEP is responsible for regulating point sources through the wastewater discharge law (38

M.R.S. Chapter 3, § 413 ), which requires that a license be obtained for the discharge of pollutants to a stream, river, wetland, or lake of the state, or to the ocean. D EP also regulat es nonpoint sources associated with development activity through administration of
the Erosion & Sedimentation Control Law (38 M.R.S. Chapter 3, § 420

- C) , the Storm Water Management Law (38 M.R.S. § 420

- D ) , the Si te Location of Development Act (38 M.R.S. Chapter 3, §§ 481

- 490), and the Natural Resources Protection Act ( 38 M.R.S. Article 5

- A )

. A major purpose of these laws is to protect Maine’s water resources. This is a ccomplished by requiring developers to use proper erosion and sedimentation control and storm water

treatment measures . In addition, DEP promotes voluntary use of best management practices for safe lawn care practices through signage (required under 38 M.R.S. § 419) and
other outreach

. . Developed A reas & NPS Pollution Sources
The 2012 I ntegrated R eport indicates developed areas are the primary source of pollution of 21 impaired lakes and 28 urban impaired streams. Pervious natural landscapes like forests, wetlands, and grasslands trap rainwater and snowmelt and allow water to slowly filter into the ground. Runoff tends to reach receiving waters gradually. I mpervious urban landscapes like roads, bridges, parking lot s, and buildings don't let runoff slowly percolate into the ground. Water remains above the surface, accumulates, and runs off in large

amounts. Storm sewer systems quickly channel runoff from roads and other impervious
surfaces. L arge volumes of quickly flowing runoff erode stream banks, damage streamside
vegeta tion, widen stream channels, increase sediment loads, and raise water temperature impacting fish and other aqua tic life

.

Unpaved roads or trails were listed in the 2012 Integrated Report as the pr imary pollution source for three impaired lakes, but it is a significant issue for many surface waters. Camp and other gravel roads contribute a disproportionate amount of sed iment deposition into
streams and lakes , due to sub

- standard construction, maint enance and their proximity to

water

. Typical problems identified through watershed surveys include : erosion of the road surface, road shoulders, and ditches; unstable and undersized culverts; poor road surface material; and inadequate ditches.Maine NPS Management Program Plan 2015

Erosion &
Sedimentation
Control Law Maine DEP has regulatory authority over land use activities through

five statutes:

The Erosion and Sedimentation Control Law is a non

- reporting

program that applies to all development activity; DEP provides training to developers, consultants and contractors on how to conduct activities in a way that complies with the law ’s requirement of preventing erosion and sedimentation at property boundaries.Maine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

30 Site Location of Development

Law

Storm Water Management

Law

Mandatory
Shoreland Zoning Act

Natural

Resources
Protection Act The Site Location of Development Law applies to larger projects that

may have a substantial effect on the environment, and include projects that occupy more than 20 acres or create three acres or more of structure (impervious areas).

The Storm Water Management Law regulates development activity
that disturbs one acre or more of land both during and after construction. Stormwater treatment BMPs are required for projects that involve more than 5 acres disturbance; 20,000 square feet of impervious area in watersheds of most at risk lakes or urban impaired streams; or 1 acre of impervious area in any other

w atershed. The Site Location of Development Law applies to projects that develop three acres or more of land (not revegetated).

DEP adopted Stormwater Rules (Chapter 500) that apply to projects
under both the Storm Water and Site Location Laws. These r ules specify what types of BMPs must be utilized. The rules require inspection and maintenance of BMPs, including a provision added in 2005 that developers must certify every five years that the required BMPs are in place and being properly maintained.

The Mandatory Shoreland Zoning Act (MSZA) , administered by municipalities with DEP oversight, requires municipalities to adopt, administer, and enforce local ordinances that regulate land use activities in the shoreland zone. The shoreland zone is comprise d of all land areas within 250 feet of the normal high

- water line of any great pond or river; upland edge of a coastal wetland ; the upland edge of defined freshwater wetlands; and all land areas within 75 feet of the normal high

- water line of certai n strea ms. The purposes
of MSZA are: to prevent and control water pollution; to protect fish spawning grounds, bird and wildlife habitat; to project buildings and lands from flooding and erosion; to protect archeological and historic resources; t o protect fishin g and maritime industries; to protect freshwater and coastal wetlands; to control building sites, placement of structures and land uses; to conserve shore cover, and visual as well as actual points of access to inland and marine waters; to conserve natural beauty and open space; and to anticipate & respond to impacts of development in shoreland areas.

The NRPA requires a permit for any activity that is in, on, over, or adjacent to protected natural resources, which include wetlands, rivers, streams, broo ks, ponds, significant wildlife habitat, and sand dune systems. Activities regulated under NRPA include: (A) dredging, bulldozing, removing or displacing soil, sand, vegetation or otherMaine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

31 materials; (B) draining or otherwise dewatering; (C) filling, includin g adding sand or other material to a sand dune; or (D) any construction, repair or alteration of any permanent structure. Protected natural resources include streams, lakes, freshwater and

marine wetlands, sand dunes and significant wildlife habitats.

Co ntractor Certification Program DEP has had a voluntary certification program for contractors on

proper erosion and sedimentation control since 1997. In 2013, the program became mandatory for any contractor doing earth

- m oving
work within 75 feet of stream s and within 250 feet of other water bodies . As a result, the number of certified contractors in the state has risen from approximately 600 to over 2,5 00. A survey in 2004 found that certified contractors have had a much higher compliance
rate with the ESC Law (>90 % ) versus non

- certified contractors (50 % ).
Promotion of safe
lawn care practices and
alternatives for
homeowners In an effort to reduce the use of fertilizer containing phosphorus in

lake watersheds, Maine enacted a law in 2008 pertaining to the sale of fertilizer. The law restricts the sale of fertilizer with phosphorus to locations where signs are placed promoting the use of phosphorus

- free fertilizer except for new lawns, or where a soil test indicates a phosphorus deficiency. Maine is a lso promoting healthier lawn care practices through the Maine Yardscaping Partnership, overseen by the Maine Board of Pesticides Con trol at
the DACF. This program hopes to inspire Maine people to create and maintain healthy landscapes through ecologically based practices that minimize reliance on water, fertilizer and pesticides. http://www.maine.gov/dacf/php/pesticides/yardscaping/index.htm

Salt m anagement Monitoring of aquatic resources in Maine has shown the presence of

chlorides. Elevated levels of c hlorides have been found particularly in urban impaired stream watersheds and are attributed to past and present stockpiles of sand and salt and to large commercial parking lots. Roads are also a contributing source. DEP has been partnering
with the Main e D O T, municipalities and SWCDs on forums to learn more about best management practices for reducing the use of salt and/or reducing its impact on water resources. Training for municipal officials, engineers and developers Communication with towns and the regulated community are vital

to ensure compliance with regulatory requirements for erosion
control , shoreland zoning, and stormwater management. The DEP provides training for the affected groups through the Nonpoint

Sourc e Training and Resource Center, which conducts spring and fall training classes on erosion control, and periodic conferences and workshops on stormwater management, as well as other related topics. In addition, DEP work s with municipal officials, includin g town engineers on latest guidance on the regulatory program. This includes providing information BMP manual updates to towns delegated to administer the state stormwater program.Maine NPS Management Program Plan 2015

## B. Agriculture

Lead Agency: Department of Agriculture, Conservation and Forestry (DACF)

Management Strategies Promote widespread use of agricultural BMPs for all agricultural operations through administration of the Nutrient Management Act and the Agricultural Compliance Program. Reduce the impact of agricultural operations on water bodies by promoting the continued implementation of site

- specific BMPs. Focus efforts to help ensure that agricultural operations: have Nutrient Management Plans, if required; achieve updates to these Plans prior to expiration; and, obtain or main tain a Livestock Operations Permit, as required by statute. Continue to provide technical assistance to farms when needed, and continue to promote and conduct farmer educational programs related to BMPs and protecting water quality. Core Law / Regulatory Autho rity The NPS Management Program statute (4 0 M

. R

. S

. Article 1

- F) charged DA C F with responsibility to develop and promote use of agricultural BMPs to preve nt nonpoint source pollution. DACF has developed voluntary and regulatory programs and provided services that help farmers use BMPs. DACF has responsibility to regulate agricultural activity to control nonpoint source pollution through administration of the Right

- To

- Farm Law, the

Nutrient Management Law and other statutes. Agriculture & NPS Pol lution Sources DEP’s 2012 Integrated Report lists agriculture as a source of impaired water quality for six lakes (10,532 acres) and 358 miles of rivers and streams. NPS pollutants of concern associated with agriculture include bacteria, soil, fertilizers and pesticides. According to
the USDA 2002

- 2007 census the number of Maine farms increased by 13 percent to 8,136. The average size of Maine farms decreased, from 187 to 166 acres. Maine has 1.3 million acres of farm land and leads the world in the production of wild blueberries. On a national scale, Maine is 1 st in brown egg production, 2 nd in maple syrup production and 8 th in potato production . Significant livestock agriculture includes cattle (dairy and beef), sheep, goats, hogs, equine and poultry. Given the increase in the number of smaller farms there is a need for increased outreach, education

, and technical assistance on the use of BMPs.

34 Program/Project Description
Administration of
Nutrient Management Law The law requires that all farms with 50 animal units or more develop

and implement a nutrient management plan (NMP). Also, a NMP
must be developed for farms that use over 100 tons of manure not generated on the farm, farms that have a manure related compl aint, and farms that utilize sludge. The law requires new or existing livestock operations with greater than 300 animal units, that meet the EPA definition of a Concentrated Animal Feeding Operation (CAFO) , or that plan on expanding beyond their land base

or manu re storage capacity, to obtain Livestock Operation P ermits (LOP) . The law prohibits the spreading of manure between
December 1 st and March 15 th

. Nutrient Management Rules establish standards for NMPs, the process for certifying persons to write an d approve NMPs; requirements for obtaining a livestock operations permit; and procedures for implementing the law. http://www.maine.gov/agriculture/narr/nutrientmanagement.html Agricultural Compliance Program This program handles complaints concerning agricultural activities

and assists with inspections req uired for issuance of LOP and CAFO permits. I nv estigations determine whether BMPs are being used, works with farmers to develop site specific BMPs, if necessary, to correct the situation, and takes enforcement action if needed.

The Compliance Program also provides technical assistance to local

communities or DEP related to agricultural problems and BMPs
called for in waters hed

- based management plans

. Nutrient Management Loan Program The program provides low interest loans for agricultural NPS

pollution abatement projects. It is administered by the Finance Authority of Maine, and was developed in cooperation with t he Maine Bond Bank, DAFC

, DEP and EPA . EPA’s Cl ean Water State Revolving Fund program provides the funding

, and Maine DACF determines eligibility for the loans.
Soil & Water
Conservation
Districts (SWCDs) SWCD are agencies of the state that help farmers, landowners,

municipal officials

, and others conserve and utilize their soil, water, forestry and wildlife resources by providing local solutions to local natural resource problems. SWCDs a re n on

- regulatory entities well

known for their ability to resolve issues effic iently at low c ost. Districts reach out to local stakeholders in the community to determine priorities and set a course of action to solve natural resource problems. This is done by offering technical assistance and educational programs to these groups. These actions help prevent and reduce pollut ed runoff to waterbodies from agricultural and urban sites, and protec t drinking water sources. D istricts collaborate with DEP on many NPS pollution prevention projects to a chieve these positive outcomes.Maine NPS Management Program Plan 2015

## C. Trans portation

Lead Agency: Maine Depar tment of Transportation (MaineDOT)

Management Strategies

P romote widespread use of an erosion control plan and the installation of effective erosion control measures with the goal of water quality protection at all transportation projects with soil disturbance through administration of the Stormwater Management Memorandum of Agreement (MOA) under Chapter 500, Stormwater Management Rules. Provide training and promote the Erosion Control Contractors Certification for all state, town

, or cont racted road

crews. Continue working under the Stormwater Management Memorandum of Agreement (MOA) under Chapter 500, Stormwater Management Rules, for the implementa tion of
statewide erosion and sediment c ontrol measures usage at new and maintenance soil
d isturbance projects and for the stormwater management of new developments. Manage hazardous materials and winter road sand/salt to reduce contamination of ground and surface

waters.

The Maine Local Roads Center will provide training, technical assistance and information to municipal staff responsible for constructing, maintaining, and managing local roads and bridges.

Core Law / Regulatory Authority The NPS Management Program statute ( 38 M.R.S. subsection 4 10

- J ) charged Maine DOT with responsibility to develop BMP guidelines for transportation

- related activities , encourage all state and federally funded projects to use BMPs, and provide technical assistance to municipalities. Transpor tation & NPS Pollution Sources

MaineDOT maintains 8,816 miles of roadway (Interstate highway, principal arterials, and collector roads). Erosion during and after construction of roads, highways, and bridges can
contribute sediment and silt to runo ff waters, which can adversely impact wa ter qu ality

. Heavy metals, oils, other toxic substances, and debris from construction traffic and spillage can be absorbed by soil at construction sites and carried with runoff water to lakes, rivers, and

marine waters. Winter road maintenance , salting and sand ing, is a significant source of the
total chloride and sediment loading to fresh waters. Inade quate road stream crossing s can disrupt stream channel morphology, cause streambank erosion and prevent natural passage of fish and other aquatic life.

contractors the importance of preventing erosion and stabiliz ing all exposed soils and compl iance with the ESC law that directsMaine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

37 "adequate and timely temporary and permanent stabilization measures will be used to prevent unreasonable erosion and

.

Maine Local Road

Center The Maine Local Roads Center provides training, technical assi stance and information to municipal staff responsible for constructing, maintaining, and managing local roads and bridges

. T hrough its newsletter and workshops, town officials and road maintenance crews receive information and guidance about the values ( e.g. , long term cost avoidance and protection of local water resources) of minimizing erosion and sedimentation from town roads and

asso ciated drainage features.

Road winter sand and salt management Maine DOT management of road sanding practices has exceeded the established goal of 40 percent redu ction of sand use since 1999.

Maine DOT plans further winter sand reduction while maintaining safe winter driving conditions. U sing an anti

- icing approach instead
of a de

- icing approach significantly redu ced the use of winter sand.
The anti

- icing approach uses mostly rock salt, but also includes salt brine, and “Ice

- B

- Gone” which w as recognized by DEP under its Design for the E nvironment Formulator Program’. Maine DOT will continue to research approaches, methods, and products to maintain safe roads and winter driving conditions with the least environmental impact.

Road winter sand and
salt storage Maine D OT r oad salt and sand/salt storage systems in all 5 regions comply with DEP regulations to protect ground and surface waters. All outdoor winter sand piles have been eliminated in Region 1, 2
and 4 . There are 30 remaining outdoor piles in Re gion 3 and 5 . This
represents a reduction of approximately 66 percent . The 30 remaining piles a re treated with either hot sand or DT50 products to prevent water infiltration.

Watershed Projects Recognizing the importance of placing stormwater management systems in areas most needed, Maine DOT has implemented several BMPs to help restore urban impaired streams. P ervious pavement was installed in the Long Creek watershed. The pavement has been placed in an area of high usage and is be ing cleaned and monitored

## D. Forestry

Lead Agency: Maine Forest Service (MFS)

Management Strategies Promote widespread use of forestry BMPs and BMP

- based programs and projects on all forest
harvest and forestry

- based operations in Maine, with special emphasis on water quality protection. Improve consistency for the regulated community by working with towns to adopt statewide standards for timber harvesting in shoreland areas. Core Law / Regulatory Authority
Under Maine’s F orest Practices Act (12 M.R.S. §§ 8867

- A to 8888) landowners are required to notify the Maine Forest Service (MFS) of planned timber harvest activit ies (with very limited exemptions for personal use and small acreage). Harvest plan s are r equired for clearcuts over
20 acres. The NP S Management Program statute (38 M

. R

. S

. Article 1

- F) charged MFS with responsibility to develop and implement forestry BMPs. Since then MFS has developed programs and provided services that help landowne rs and wood harvesters use BMPs in accordance with MFS advisory and regulatory programs.

Fores try and NPS Pollution Sources
About 89 percent of Maine is forested, the highest percentage of any state. Forest products are a key part of Maine’s economy with roughly 200 forest products businesses employing

17 ,000 people. Approximately 450,000 acres are harvested annually, via 5,500 to 6,000 harvest operations. Constructing forest roads, trails, landings

, and drainage systems can reduce soil absorbency, divert or concentrate water flows, cause soil erosion, increase
sediment and nutrients entering streams

, and diminish the benefits of vegetation next to
water bodies. Harvesting may also reduce shade on th e water’s surface, reduce the amount of natural woody debris

, or eliminate food sources for aquatic life. Timber harvests that remove a significant percentage of trees can increase the water runoff into streams, in some cases increase flooding. Forestry BMPs mimic or protect natural forest functions, absorb or disperse runoff, retain soil nutrients, filter sediment, an d help maintain natural water temperature.

- 500 foresters, loggers and landowners. MFS also partners with several logger certification and professional organizations including the Certified Logging Professional Program, Northeast Master Logger, Qualified Loggi ng Professional Program and the Professional Logging
Contractors of Maine to deliver BMP training in conjunction with other scheduled trainings and events. These partnerships allow MFS to reach over 1000 loggers per year with BMP

- related training.

For estr y BMPs for Water Quality

- Manual & Training The MFS made minor revisions to the state’s forestry BMP manual in

2010. The manual is published in English and French language versions
and has proven to be a useful program tool. Trainings are based on establishing a strong understanding of BMP principles to promote
better in

- the

- field applications of specific practices detailed in the manual. The standard BMP training program was revised in 2012. Training Programs Specific forestry BMP training topic needs are identified via regular BMP

monitoring and interaction with partners and other outside sources. Once needs are identified, MFS works with its partners to either develop training in

- staff adult education expert who assists with all MFS training development. Recent topic

specific training has included designing road stream crossings to allow fish passage, and road grading for road rehabilitatio n and maintenance. Forestry BMPs
, use and effectiveness Monitoring MFS has conducted random statewide monitoring of BMPs on timber

harvesting operations since March, 2000. The objective is to assess the use and effectiveness of forestry BMPs in Maine. C urrently the MFS
cond ucts BMP monitoring on a biennial basis, evaluating approximately 120 harvest sites. This effort has become part of MFS regular operations and is likely to continue as long as resources are available. The BMP protocol project was a co operative effort of the Forest Service, U.S. Department of Agriculture, and the Northeastern Area Association
of State For esters

– Water Resources Committee

. R eports and protocol
can be found at: http://www.maine.gov/doc/mfs/fpm/water/bmp_monitoring.html Since Maine’s BMPs are voluntary and designed to be outcome

- based, the protocol focuses on effectiveness and implementation rather than strict BMP compliance. This is done by recording measurable evidence and assessing a suite of BMPs rather than evaluating the installation of individual practices. The protocol evaluates: s tream c rossings and

a pproaches; r iparian buffers; c hemical p ollution; w etland c rossings and

a pproaches; h aul r oads, l og l andings, and r utted m ineral s oil in
b uffer/ f ilter s trips.
MFS Direct

- Link Loan Program Since 2007 the MFS has partnered with the Maine Municipal Bond Bank

,

DE P , and several participating banks to provided low

- interest incentive financing to loggers who purchase equipment capable of implementing BMPs to reduce NPS impacts on timber harvests. This program requires that participants receive BMP training from the MFS and maintain their certification by one of the state’s logger certification programs. Participants are also subject to follow

- up BMP inspections by the MFS. Since program inception roughly 60 loggers have made equipment purchases with program assistance. Funding is from EPA’s Clean Water

State R evolving F und. Portable Forestry Bridge Loaner Program The MFS partners with several mills around the state to provide

portable bridges to loggers on a loaner basis, free of charge. The program has five sets of steel bridges and many sets of wooden bridges
in circulation around the stat e. These bridges allow loggers to ‘try out’ this BMP without cost, and several loggers have purchased or constructed their own bridges after using the loaner bridges.
Watershed Projects Recognizing the importance of placing resources in areas of most need

and where they can do the most good, the MFS has invested effort on the Sebago Lake watershed through a major US Forest Service grant. Specifically, this project has provided cost

- share assistance to over 15 loggers for the purchase of portable forestry bridges; conducted BMPMaine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

41 implementation and effectiveness monitoring on every timber harvest over 15 acres conducted in the Sebago Lake watershed over the last 2 years; provided cost

- share assistance to woodland owners and towns for the preparation of forest management plans; and provided grants to towns for tree planting projects. MFS expects to replicate this effort in
the future. Coarse Woody Debris Program The MFS has developed a progr am to increase the number of coa rse

woody debris (CWD) additi on projects in Maine. In 2012 it worked to simplify the process for implementing CWD projects by writing
rule s /standards allowing trained licensed foresters to oversee CWD projects without the need for a permit. The MFS in cooperation with the Department of Inland Fisheries and Wildlife has developed and delivered training to foresters who will oversee these projects.
Timber Harvest Inspection/Water Quality
Enforcement Although Maine BMPs are voluntary, there are state laws prohibiting

landowners from al lowing sediment to enter water bodies. Landowners must notify the MFS of all commercial harvesting activity, which allows Maine’s 55 Forest Rangers to ins pect the harvests for compliance with timber harvest regulations. Notifications must indicate whether harvests occur near waterbodies, allowing inspections to be prioritized by potential environmental risk. The MFS uses cooperative agreements with DEP and the Land Use Planning Commission whereby MFS rangers inspect harvests for compliance using environme ntal laws administered by these agencies. The MFS has also recently assumed regulatory jurisdiction of harvesting and related activities in shoreland areas for many areas of the state. This is part of the transition from a dual set of regulations in the unorganized and organized areas of the state

, to a consistent set of statewide regulations and a single regulatory authority.

Demonstration Projects MFS regularly helps organize technology transfer demonstration

projects. Most of these projects demonstra te innovative stream crossing installations, particularly those involving designs promoting fish passage, including ‘bottomless arch’ and box culverts and low

- cost bridge installations.
Forest Certification Programs &
Initiatives The MFS supports forest certification by any of the several organizations

that certify forest land in Maine. These organizations include the Forest Stewardship Council, the Sustainable Forestry Initiative and the American Tree Farm System. A bout 9.4 million acres of Maine’s forests are certified to one of the three major standards. Use of water quality BMPs is mandatory under all of these systems. Lands certified under these systems undergo third

- party audits, offering an added level of scrutiny wit h regard to the implementation and effectiveness of BMP practices.Maine NPS Management Program Plan 2015

## E. Onsi te Wastewater Disposal Systems

Lead Agency: Department of Health & Human Services, Maine Center For Disease Control, D ivision of Environmental Health, Subsurface Wastewater Unit

M anagement Strategies Work with municipaliti es to implement the Subsurface Wastewater Disposal ( SSWD ) Rules. Improve the voluntary training and certification programs for septic sys tem inspectors and

installers ( Voluntary Onsite Sewage Disposal System (OSDS) Inspection Program )

. Continue to
encourage point

- of

- sale septic system inspections.

Revise and update the SSWD Rules as needed to address emerging issues and to reflect current technology in subsurface waste water management and disposal.

Core L aw / Regulatory Authority By Maine statute (22 M.R.S. §42) the Department of Health and Human Services (DHHS) is authorized to adopt rules providing for the inspection of plumbing and subsurface wastewater disposal systems. The rules are known as the Subsurfa ce Wastewater Disposal Rules (10

- 144 CMR 241). Implementation and enforcement of the rules is the responsibility of municipalities. Municipalities are required to appoint plumbing inspectors to implement the rules

. Onsite Subsurface Wastewater Disposal Systems & NPS Pollu tion Sources

Onsite SSWDs are utilized for the treatment and disposal of domestic and commercial wastewater in areas that lack centralized municipal wastewater collection and treatment systems. Onsite SSWD s ystems , if improperly located, designed, or installed are subject to malfunction, which may cause adverse health effects and detrimental environmental impacts to land and water resources from untreated wastewater. Malfunctioning disposal systems can
cause bacter ial contamination and deliver nutrients to surface waters.
BMP Guidelines Subsurface wastewater disposal rules govern the siting, design, construction

, and inspection of subsurface wastewater disposal systems in order to protect the health, safety

, and welfare of the citizens of Maine. Approved procedures, design

, and siting requirements, materials,
methods

, and administrative polices are described in detail. These Rules provide minimum State design criteria for subsurface wastewater disposal to a ssure environmental sanitation and safety. These Rules are intended to complement municipal planning, zoning, and land use

43 Program Description

Subsurface Waste Water Disposal Rules (CMR 241) Maintain copies of all plumbing and subsurface waste water permits issued statewide. Approximately 40,000 plumbing permits are processed annually, which generate approximately $275,000 in

dedicated revenue. The Program processes approximately 10,000
subs urface waste water permits annually. Provide reviews of engineering plans for compliance with or variance from departmental rules in support of the Division's various program areas. Provide interagency reviews and make recommendations for DEP, Maine Land Use Regulation Commission, Maine Department of Education, and Bureau of Public Improvements, among others. Conduct site inspections to assist site evaluators, local o fficials, and property

owners. Rules for Appointment and
Administration of
Local Plumbi ng Inspectors (CMR 240) Oversee the appointment and administration of Local Plumbing Inspectors, including the eligibility, application, examination, an d re

certification requirements

.

Rules for Site
Evaluators of
Subsurface Wastewater Disposal Systems (CMR 245) Oversee licensing of site evaluators that perform subsurface wastewater disposal evaluations for the purpose of designing onsite subsurface wastewater disposal systems. This includes the administration, examin ation and licensing roles.

Voluntar y Onsite Sewage Disposal System Inspection Program. Th e Department oversees a Voluntary Onsite Sewage Disposal System Inspection Program for inspection of existing systems.

Certification of
Subsurface Wastewater Disposal System Installers The Department oversees a voluntary certification program for SWDS installers. The program involves training programs, review of actual performance and on

- going 5

- year recertification with continuing education and good performance. Small Community Grants Program DEP administers the Small Community Grant Program, which provides grants to towns to help replace malfunctioning septic systems that are polluting a waterbody or causing a public nuisance. Grants can be used to fund from 25% to 100% of the design and const ruction costs, depending upon the income of the owners of the property, and the property's use. An actual pollution problem must be documented in order to qualify for funding. The highest pri ority is given to problems
that are polluting a public drinking water supply or a shellfishing area.Maine NPS Management Program Plan 2015

## F

. Hydrologic Modification

Lead Agency: Maine Department of Environmental Protection

Management Strategies Control hydrologic modification of river s , streams

, and lakes through administration of regulatory programs. Coordinate review and permitting of channel dredging with the Army Corps of Engineers (ACOE). Control impacts of hydropower dams through certification of Federal Energy Regulatory Commission ( FERC ) hydropower permits. Regulate impacts of other dams through state review of water level petitions and subsequent DEP water level orders. Encourage use of erosion and sediment controls and stormwater management BMPs through
both administration of land use laws and prom otion of voluntary measures by continued
administration of the Storm Water Management and Site Location of Development Laws.Adopt new standards for stream crossings (new, repair, replacement, rehabilitation) designed to improve fish passage, h ydraulic capacity and resiliency to larger storm events.

Core Law / Regulatory Authority

D EP regulates channel dredging through the NRPA in conjunction with the ACOE under section 404 of the Clean Water Act. Licensing of hydropower dams is regulated by t he FERC and conditions required by states under section 401 of the CWA to ensure attainment of S tate Water Quality Standards. Non

- hydropower dams are regulated under the Maine Waterway Development and Conservation Act ( 38 M.R.S. §§ 630

- 636, 640) , Maine Wa ter Level Act ( 38

M.R.S. §341

- D, §§2)

, Municipal Regulation of Water Levels and Minimum Flows Act (30

- A

M.R.S. § 4454

- 4457) , and DEP’s In

- Stream Flows and Lake and Pond Water Levels rule. DEP is responsible for controlling runoff and erosion through the ESC Law, the Storm Water Management Law, the Site Location of Development Act and NRPA

. Hydrologic Modification and NPS Pollution Sources DEP’s 2012 Integrated Report lists hydromodification as the source category for 85 miles of impaired rivers and streams and seven impaired lakes ( 48,994 acres)

. Hydrologic modification activities include dams, channelization, channel modification, and streambank and shoreline erosion. Channelization, channel modi fication, and stream crossings may adversely impact suitability of instream and streamside habitat for fish and wildlife. Several recent watershed

level surveys of existing Maine stream cros sings indicate that as many as 90 % are barriers to fish passage an d as many as 40 % are impassable, causing significant loss of aquatic habitat. Hydro logic modification can alter instream water temperature, and sediment erosion, transport and deposition. The siting, construction and operation of dams can adversely impact the hydraulic regime, water levels, surface water quality and habitat of a lake, stream or river. Erosion caused by hydrologic modification can have adverse impacts on riparian habitat. Excessively high sediment loads can smother submerged aquatic vegeta tion, cover shellfish beds and tidal flats, fill in riffle pools, and increase levels of turbidity and nutrients.

CMR Ch. 587 This Chapter establishes river and stream flows and lake and pond

water levels to protect natural aquatic life and other designated uses in Maine’s waters. Instream flow requ irements for Class AA, A, B, and C waters are based on natural flows that occur in Maine waters, and the uses and characteristics assigned by the water quality classification

prog ram (38 M.R.S. Sections 464, 465) with attention given to protecting the outs tanding natural resources associated with Class AA waters. Flow is managed to provide natural variation of flow described by seasonal aquatic base flows, or other seasonally variable flows, shown to protect aquatic life resources and water quality standard s. Water level requirements for Class GPA waters take into account natural variation of water levels that occur in Maine lakes and ponds, and the uses and characteristics assigned by the water quality
cl assification program (38 MRS Sections 464, 465

- A). Wa ter level is managed to provide variation that takes into account expected seasonal levels shown to protect aquatic resources and other water quality standards of Class GPA and downstream waters. Instream flows and water levels may be established by 3 meth ods: (1) standard allowable alteration, (2) by a site

- specific flow designation developed through an Alternative Water Flow or Alternative Water Level, or (3) as part of a new or existing regulatory permit. A water use which fails to comply with the requir ements of these rules is subject to penalties pursuant to Title 38, Section 349. Develop new
standards for stream crossings (new, repair, or replacement) designed to improve fish passage, hydraulic capacity and resiliency to larger

storm events New stream crossings, as well as the maintenance, repair,

rehabilitation and replacement of existing crossings, are regulated
under the Natural Resources Protection Act. Several watershed

- level surveys of existing crossings revealed surprisingly consistent results indicating that as many as 90 percent are barriers to fish passage and as many as 40 percent are impassable. In an effort to reestablish the connectivity of Maine’s stream systems, the Legislature directed the Department, in concert with the Department of Transportation and other state natural resource agencies to develop an Aquatic Resource Management Strategy.

A major stakehol der group has been working on this issue since late 2011. By 2015 , it is anticipated that new standards will be adopted for

new and replacement crossings designed to improve fish passage, hydraulic capacity and resiliency to larger storm events. Efforts are also underway to identify funding mechanisms, develop training programs and to assess and prioritize watersheds where removin g passage impediments will result in the greatest connectivity of
fisheries habitats.Maine NPS Management Program Plan 2015

## G. Other NPS Sources

The preceding sections describe six major NPS categories in Maine. Boatyards and Marinas and Land Disposal are no longer major sources of NPS poll ution. Regulatory programs have reduced the water quality threat from these 2 NPS categories.

Boatyards and Marinas Because of their proximity to water, marine facilities including boat repair yards, marinas, commercial piers, and boat ramps can adversely affect water quality. M any types of pollutants including fuels, oils, grease, antifreeze, cleaning materials, fish waste and solid waste can get into nearby water s

. In large part, marine facilities are regulated by the MEPDES program, through b oth the Industrial Multi

- Sector General Permit and the Waste Discharge Program. In addition, marine facilities may be subject to regulation for fuel storage, hazardous, solid or

sanita ry waste, and air discharges. C ommercial piers and municipal or state b oat ramps are potential sources that are not regulated.

DEP plays the lead role in carrying out these regulatory

programs and providing technical assistance and outreach efforts for boatyards and marinas

. The DEP manual, Brightwork: Best Management Practices for Maine’s Boatyards and Marina (2004) provides guidance
on the various BMPs such as fish waste and bait management, boat cleaning, fuel spill prevention, solid waste management and sediment and erosion controls

.

T he Maine Marine Trade Associa tion (MMTA) leads a voluntary

, beyond complianc e initiative helping boatyards and marinas operators meet and exceed
environmental standards. The Maine Clean Boatyards
and Marinas P rogram is a collaborative partnership among industry, state and federal age ncies and environmental organizations dedicated to promoting BMPs in boatyards and marinas. The

p rogram helps p rotect and improve clean water by helping boatyards and marinas reduce pollution beyond the regulatory requirements. DEP will continue working w ith the MMTA on
the Maine Clean Boatyards and Marinas Program

48 Land Disposal

W aste disposal was historically a significant NPS problem in Maine. Waste and l eachate
delivered toxics and nutrients to surface and ground waters

. Fortunately

, several laws have been enacted over the past several decades , and waste disposal activities are now highly regulated and monitored. In fact, m ost of Maine’ s landfills are currently inactive or have been
closed (F igure 11). There are now only a small number of highly regulated landfills, including 27 municipal operations

.
The State of Maine supports an integrated approach to waste management. This includes programs to reduce the amount and toxicity of waste gen erated, promote reuse and recycling of waste, and compost and process waste to create safe and useful products. Disposal through incineration and landfilling is the least preferred option.

DEP ’s solid waste programs include solid waste facilities managem ent, sludge and residuals management, scrap tire management, electronic waste and mercury product management, and the

non

- hazardous waste transporter program. These programs provide
education a nd technical assistance and
carry out regulatory activities inc luding licensing, compliance and enforcement of
the State’s Solid waste laws. Figure 11

## VII I

. NPS Pro grams and Partnerships

A. DEP NPS Programs

DEP conducts focused work on NPS issues through the NPS Grants Program, NPS Technical

Assistance Services and NPS Outreach. The following section describes these program areas and identified management strategies associated with each.

NPS Grants Program DEP administers a pass

- through grants program that
awards and monitors sub

- grants of EPA Section 319 & 604b
funds (Clean Water Act) for watershed projects to help restore or protect lakes, streams, rivers

, or marine waters from NPS pollution. These grants help communities identify nonpoint water pollution sources, prepare watershed

based management plans, and take action to reduce or prevent NPS pollution. DEP Agreement Administrators are assigned to each NPS project to monitor grantee progress

in impleme nting the project and provide technical support to help grantees suc cessfully carry out projects. DEP provides opportunity for two types of grants to help

communities:

 Devel op a watershed

- based plan (WBP)

- A WBP provides assessment and management information and
describes actions needed over a five to 15 year period

to restore NPS

- impaired water bodies, or to protect water bodies threatened by NPS pollution. The extent of the planning area (watershed) needs to be a geographically

- appropriate size so that implementing actions can lead to measurable reductions in pollution and achieve ment of water quality goals.

 I mplement a watershed

- based plan.

- Grants are available to help partners make progress carrying ou t NPS management measures (actions) described in the plan. A WBP accepted by the DEP is a prerequisite to be eligible to apply for NPS grant funds to help implement the plan.

DEP administers Section 319 grant award received from EPA in accordance with the national EPA guidance for state NPS management programs and the EPA

- DEP Performance Partnership Agreement (PPA). EPA guidelines designate the annual 319 award into two categories

– “NPS program funds” and “watershed project funds”. States may use 50 pe rcent of their Section

319 grant allocation (NPS program funds) to support any eligible NPS activities in the State NPS management plan

. States are required to use at least 50 percent of funding (watershed project Sample 319 grant project: eroding lake shoreline before BMP implementation.Maine NPS Management Program Plan 2015

50 funds) to implement on

- the

- ground watershed projects guided by a watershed based plan. Watershed project funds are for restoring impaired waters through the implementation of a WBP or to implement alternative plans approved by EPA, such as protecting unimpaired waters designated as a priority in a State NPS Plan. Project funds may not be used for planning activities s uch as WBP or TMDL development

In Maine, Section 319 “NPS program funds” will be used primarily to support DEP staff performing NPS program services, training programs through the NPS Traini ng and

R esources Center, and assess ment of water quality trend for lakes where there has been NPS pollution control activities thr o u gh the Maine
Volun teer Lake Monitoring Program. DEP expects to use a limited amount of program funds to help develop new WBPs. Sec tion 319 “Watershed project funds” will be used primarily for implementation of WBPs to help restore NPS impaired waters or alternative plans to protect unimpaired waters that are considered threatened. DEP plans to use up to 50 percent of watershed proje ct funds for implementation of WBPs to help communities protect unimpaired
waters that are considered threatened or most at risk. Sample 319 grant project: Installation of a covered manure storage facility, heavy use area and vegetated runoff treatment system at a dairy farm to minimize and treat phosphorus runoff to nearby lake.

51 Technical Assistance Services

In addition to the support provided to active 319 projects, DEP invests considerable staff resources to provide technical support to watershed groups, municipalities and other partners. Some of the main areas of support are described below.

 Watershed Association Support

– DEP staff support the work of lake and watershed associations through presentations, meetings and other technical assistance. DEP provides
information to hel p groups understand their watershed’s NPS issues and evaluate available options for further assessment and remediation. Staff also promotes the use and adoption of the NPS Site Tracker, which helps groups manage information on erosion sites in their

water sheds. The tool allows prioritization of erosion sites, tracking of sites as they are fixed, and listing of new sites as they
are discovered.

 Watershed Surveys

– Watershed Surveys find, document, and prioritize NPS pollution sources in a
watershed and recommend BMPs needed at specific NPS sites. Many of these surveys are funded in part through the NPS Grants Program. In addition, DEP provides
technical assistan ce and project oversight to smaller watershed survey projects that are conducted with local funding.

 Watershed Roundtable

– DEP hosts an annual Watershed Roundtable for watershed managers from state agencies, municipalities, watershed organizations, SWCD s , and the private sector. This informal, day

- long event provides an opportunity for networking, sharing lessons learned, and discussing common problems in both rural and urban
watersheds across the state.

 Youth Conse rvation Corps (YCC)

– The DEP provides technical assistance and training to the State’s nine YCC programs. These YCC programs hire high school students to install buffers, erosion control measures, and other conservation practices in lake and river

waters heds. Most of these programs originally started as part of 319 grant projects, but communities then secured local funding to continue the programs after the grants ended. YCC crew members taking a break. Volunteers for a lake watershed survey.Maine NPS Management Program Plan 2015

52 Excerpt from Maine Statewide

Bacteria TMDL (2009).  Municipal Comprehensive Plan Reviews

– DEP provides maps and waterbody information to municipalities working on comprehensive plan s, which are required under the Comprehensive Growth Management Act ( 30

- A MRS § 4311) . After plans are submitted to the state, DEP reviews the water resources sections of municipal comprehensive plans for consistency with agency goals, programs

, and policies. Suggestions are also provided for possible strategies to address NPS threats and problems.

 Bacteria TMDL Follow

- Up

– Since 2010, DEP
has conduct ed follow

- up monitoring related to the Statewide Bacteria TMDL, which was approved in 2009. The objective is to identify specific sources of bacteria through sampling for E. coli and sanitary surveys; eliminate these problems; and remove the impaired

stre am segment from the 303d list. Sampling
areas are selected from the TMDL list based on high restoration potential; adverse impact on downstream beaches; follow

- up on previous sampling efforts; and to
characterize natural levels of bacteria at
clean sites. Samples are collected using a diagnostic approach that helps narrow down NPS inputs to specific subwatersheds and identifies manageable areas for sanitary

surveys.

NPS Outreach NPS pollution is the result of a myriad of individual actions throughout a watershed. While many important polluted runoff sources can be controlled through administration of local ordinances or state regulations , outreach promoting voluntary use of BMPs can effectively prompt more widespread use of BMPs. DEP carries out several programs that promote voluntary adoption and use of BMPs to address NPS pollution. Some of the main outreach

activities are described below :

 Nonpoint Source Training and Resource Center (NPSTRC)

– The NPSTRC provides training to various groups throughout the state to help them prevent NPS pollution. Training topics
include erosion and sediment control ; stormwater management ; and septic system installation, design

, and inspection. The NPS Training Center coordinates the Contractor Certification Program, which is required for contractors that disturb soil in the shoreland zone. The Center also coordinates conferences; develops and maintains vari ous publications and a video lending library; and acts as a clearinghouse for NPS and BMP
information.Maine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

53  P hosphorus

- Free Fertilizer Effort

– Maine law (38

MRS 419) requires stores that sell fertilizer to post

DEP

- approved signs explaining when it is appropriate to use fertilizers with phosphorus. DEP help coordinate the implementation of this law by providing retailers signs and other supporting
materials about fertilizer use

.

 Outreach to Municipal Officials

– DEP offers NPS training for municipal officials to help provide services formerly provided by t he non

- profit program, Nonpoint Education for Municipal Officials (NEMO ), which was discontinued in 2013

. DEP plans on us ing Adobe Presenter to produce 20 minute educational programs and on

- line resources on topics such as NPS pollution prevention and low impact development. These will be marketed though the Maine Municipal Association and DEP’s municipal new sletter. Limited assistance will also be provided to municipalities that view the modules and would like additional information (e.g.

, ordinances changes).

 Target Audience Analysis

- Effective outreach segments audiences into discrete groups of people with common characteristics and then
facilitate s a more effectively targeted outreach effort. DEP’s NPS Outreach Program aims to understand key target audiences and then use
this knowl edge to effectively influence BMP use. DEP has funded and supported research efforts such as phone surveys, focus groups

, and intercept surveys to gather information on current behavior, beliefs, values

, and barriers to behavior adoption. DEP then provid es t his
information to partners who are working to promote water quality efforts.

 NPS Outreach Assistance to 319 Grant Projects

– DEP provides outreach assistance to partners developing and implementing watershed based plans to make sure that outreach
eff orts are as effective and targeted as possible. The guidance document, Outreach Guidance for NPS Watershed Implementation Projects (DEP, 2008)

, has been developed for grantees. DEP also provides staff support to help identify the target audienc es that are key to advancing water quality improvement and protection. Once the audience is identified, projects can tap into existing programs or, if needed, design new ones based on the fundamentals of effective behavior change science.

 NPS Outreach A ssistance to Partners

- The most effective way to promote voluntary use of BMPs is through one on one contact and local outreach. Since DEP doesn’t have the staffing Municipal officials learn about BMPs. DEP

54 or local reach to effectively accomplish voluntary BMP adoption on a statewide basis, DEP partners with and supports local organizations. These organizations and programs deliver local behavior change efforts through technical assistance, educational oppo rtunities, and

cost

- sharing. The organizations include statewide organizations with a local presence such as Maine Lakes Society’s LakeSmart program and the Maine Board of Pesticide Control’s YardScaping program.

DEP has identified a number of important target audiences who in one form or another can have a significant impact on the quality or quantity of stormwater runoff. These audiences typically need encouragement to voluntarily implement BMPs. BMP promotional efforts and programs for several targe t audiences are described below.

## B. Integration with Other Government Programs that Protect Water Quality

In addition to th e DEP programs mentioned in the previous section, , there are many other DEP, state, federal and municipal programs that help protect and restore water quality. The most prominent NPS

- related programs are described below.

Environmental Protection Agency The U.S. EPA provides annual funding to help DEP carry out NPS Programs through Section 319 of the Clean Water Act. EPA personnel also provide extensive program guidance and technical assistance for the NPS Grants Program to ensure compliance with EPA gui delines and reportin g requirements. In 2014 the ann ual 319 program grant to Maine wa s $1,766,269. In addition to 319 funding, EPA provides other funds for water quality related programs and activities including Section 604(b) funds for water quality plan ning , the Maine Healthy Beaches Program and the National Estuary Program. EPA and DEP performance objectives, priorities and commitments are detailed in an annual Performance Partnership Agreement.

Maine Coastal Program In 1978, the federal National Oceanic and Atmospheric Administration approved the Maine Coastal Program (MCP) as the State’s coastal zone management plan in accordance with the federal Coastal Zone Management Act (CZMA) (15 U.S.C. § , et seq. ). The MCP w orks to improve the environmental and economic health of Maine’s coastal areas in accordance with the CZMA and the general policies stated in the state’s Coastal Management Policies Act (38 MRS § 1801). The Department of Agriculture Conservation and Fores try’s Bureau of Geology, Natural Areas, and Coastal Resources is the lead agency for administration
of the MCP. Several state agencies, primarily DEP and DMR, play key roles in implementing Maine’s networked program. The MCP’s activities center on the de signated state “coastal area”, which is comprised of the land area of all municipalities on tidally

- influenced waters and
coastal waters and the all islands within them seaward to the three

- mile limit of state ownership.

The MCP’s NPS

- related efforts foc us primarily on planning related to the interaction of land uses and coastal water quality. Watersheds of shellfish growing areas are a major focus; as required by NOAA, MCP has a newly

- instituted goal and indicator program to track progress in opening s hellfish growing areas for harvesting. While ME DMR administers the shellfish classification program, MCP provides technical support to municipalities to develop municipal plans, policies and ordinances that address coastal pollution in shellfish growing area watersheds. MCP administers a competitive grant program for municipalities and regional organizations that may fund NPS

- related projects such as water quality monitoring, pollution source surveys, and habitat restoration; and assists coastal organiza tions applying for CWAMaine NPS Management Program Plan 2015

56 Section 319 funds. MCP also provides limited funding to Regional Planning Councils in nine coastal regions that may assist coastal municipalities with NPS

- related issues, among
others. MCP’s Community Planning and Assistance Prog ram, which supports smart growth strategies, low impact development, and other land use planning, and the MCP’s outreach program, which educates the public about coastal issues and promotes good stewardship, also contribute to the state’s approach to NPS m anagement.

Maine DEP Stormwater Program (Maine Pollutan t Discharge Elimination System) Since 1987, EPA has had authori ty under the federal Clean Water Act to regulate certain stormwater discharges as point source discharge s through the National Pollution Discharge Elimination System. EPA developed specific stormwater requirements for construction sites, industrial activities and for discharges from municipal separate stormwater sewer systems (MS4s). In 2001, EPA delegated authority to DEP to administer this program ( now referred to as MEPDES).

 Construction General Permits

- In 2003, DEP issued general perm its for point source

stormwater discharges from construction activity. This general permit applies solely to construction activity and not to ongoing stormwater management following construction. The permit sets standards for managing stormwater that may pick up pollutants, including soil and discharge them to waters of the State such as lakes, streams, and wetlands. The requirement for a permit is triggered by the amount of disturbe d area created during construction, and whether the site will directly discharge to surface waters of the state.

FMI

- http://www.maine.gov/dep/land/stormwater/construction.html

 M unicipal Separate Storm Sewer Systems (M S4 )

- In 2003, DEP also issued general permits for discharges from MS4s in certain regulated communities. In 2013, there were 40 entities regulated through this program, including 30 municipalities, eight State o r F ederal

- Owned facilities and two transportation agencies. Regulated entities are required to develop and implement a stormwater program management plan that addresses the following six Minimum Control Measures: public education and outreach on stormwater impacts; public involvement and participation; illicit discharge detection and elimination; construction site stormwater runoff control; post

- construction stormwater management in new development and redevelopment; and pollution prevention/good housekeepin g for municipal operations.

57  Industrial Multi

- Sector General Permit

- In 2005, Maine’s Multi

- Sector General Permit, was issued for point source stormwater discharges associated with industrial activity. Regulated entities are required to develop and implement a Stormwater Pollution Prevention Plan, which includes general gui delines as well as specific standards for each listed industrial activity. The Industrial Stormwater Unit provides technical assistance, training, outreach and support to help the Maine business community meet permit requirements.

FMI

 Long Creek Watershed

- In 2009, DEP issued a MEPDES general permit for post

- construction discharges of stormwater from propert ies with one acre or more of impervious area in the Long Creek watershed, an urban impaired stream located in the municipalities of South Portland, Westbrook, Portland

, and Scarb orough. Operators of properties that have a designated discharge are required to obtain a n Individual Waste Discharge License from the Department or file for co vera ge under the Long Creek General Permit which requires permittees to participate in and comply with implementation of the Long Creek Watershed Management Plan, which is bein g carried out by the Long Creek Watershed Management District.

Maine Department of Marine Resources (DMR)

DMR was established to conserve and develop marine and estuarine resources through scientific research, promotion of the coastal fishing industry, and implementation of laws and regulations. DMR’s Shellfish Growing Area Program determines shellfish growing area c lassifications in all shellfish harvesting areas to ensure that only pollution

- free areas are open to harvesting. Classifications are set through sanitary surveys that include a shoreline survey to identify pollution sources that may impact water quality; marine water sampling to determine fecal coliform bacterial levels in the marine water; and analysis of how weather conditions, tides, currents, and other factors may affect the distribution of pollutants in the area. Water samples are collected monthly f rom January through December , to determine bacteria levels

. DMR sanitary surveys have identified NPS pollution as the likely sources of bacteria in numerous shellfish harvesting areas in the state. This information, in turn, has been used by DEP to help identify NPS Priority Watersheds.

Maine Climate Change Adaptation
The report, People and Nature Adapting to a Changing Cli mate: Charting Maine’s Course (DEP, 2010) contains more than 60 recommendations for action to plan for changes to Maine’s
climate. The report emphasized the need for planning and action at the local level, and recognized that cre ation of an actionable state

- level climate adaptation plan requires years of work and significant expenditure of resources to assure widespread acceptance and implementation. Many of the recommendations in the 2010 report a re being implemented,Maine NPS Management Program Plan 2015

Mai ne Drinking Water Program (DWP) The Maine Drinking Water Program, which is part of the Center for Disease Control, implements the Safe Drinking Water Act. The program uses EPA’s multiple barrier approach to help keep water safe and secure. Source protection is the program’s primary foc us since poorly planned and managed development represents the greatest risk to water quality and quantity. Key DWP partners include Public Water Systems (PWSs) and Maine Rural Water Association. None of these groups have authority to manage land use. H owever, the DWP, PW S s and DEP collaborate on projects in a number of drinking water watersheds. The DWP also provides input on state

- wide priorities for 319 projects and provides PWSs with financial resources that can be used to enhance NPS projects. The DWP is also a key partner in the Salmon Falls Watershed Collaborative, which is

an inter

Maine Healthy Beaches Program (MHB ) Program
The MHB program was established to ensure that Maine's salt

- water beaches remain safe and clean. The program brings together communities to perform standardized monitoring of beach water quality, notify the public if bacteria levels threaten human health, and educate both residents and visitors on ways to keep Maine's beaches healthy. The MHB program is funded by EPA under
the Federal Beaches Environmental Asses sment and Coastal Health Act; administered by DEP; and carried out in partnership with University of Maine Cooperative Extension. There are 29 beach management entities in the MHB program. While the focus of the program is to monitor bacteria levels at beaches, entities finding high bacteria levels at beaches often expand testing into feeder streams to help
determine bacteria l sources.

Municipalities Maine includes 488 organized municipalities that provide a wide range of services and responsibilities associated with self

- government. Municipal roles related to NPS include road construction and maintenance, comprehensive planning, and g rowth management . Most municipalities have planning boards that carry out laws and ordinances related to comprehensive planning and growth management functions. The Municipal Su bdivision Law ( 30

- A MRS § 4401) requires planning boards to review subdivisions using the criteria set out inMaine NPS Management Program Plan 2015

59 the statute. The Comprehensi ve Growth Management Act ( 30

- A MRS § 4311 ) encourages municipalities to identify tools and resources to effectively plan for and manage future development within their jurisdictions . The Mandat ory Shoreland Zoning Act ( 38 MRS § 435) requires the adoption of local shoreland zoning ordinances that regulate lands within 250 feet of normal high water of certain water bodies and wetlands.

Since M aine is a ‘home rule’ state, municipalities have broad authority to adopt additional local land use ordinances. Site Plan Review Ordinances have been adop ted by numerous municipalities under the authority of home rule to regulate developments which normall y cannot be reviewed as subdivisions. A smaller number of municipalities have also adopted ordinances limiting phosphorus export from single

- lot development, promoting low impact development practices or creat ing set

- backs along small headwater streams. In addition to local ordinance work, 30 municipalities are part of the MS4 program

, which addresses NPS issues from municipal stormwater systems. The Maine Municipal Association (MMA) is a non

profit organization that provides services advocacy, education and information, professional legal and personnel advisory services, and group insurance self

- funded programs for member municipalities. Numerous municipalities have also become involved in and provided support for 319 grant projects and other community e fforts to protect and restore local water quality.

Municipal Planning Assistance Program This program , which is housed in the Maine DACF helps municipalities manage growth to enhance economic development and natural resource protection. MPAP works with towns throughout the state’s organized area. The MCP funds planning staff whose efforts focus on
coastal communities and coastal issues. In In addition to administering Maine's Growth Management Act, program staff regularly provide technical assistance to local and regional planners, other municipal officials and volunteer boards on the development of land

- use ordinances, interpretation of state land use laws, the local comprehensive planning process, and numerous other matters. The program also collaborate s with other state agencies on the development of policies, rulemaking, comprehensive resource assessments, and other strategic

Natural Resources Conservation Service (NRCS) , USDA

T he NRCS administers multiple federal Farm Bill programs that provide technical and financial assistance for implementation of water quality practices. The 2008 Farm Bill provided added opportunities for leveraging funding and other resources to improve water quality affected by agricultural and silvicultural NPS pollution. The Environmental Quality Incentives Program (EQIP) now states that “reducing NPS pollution, such as nutrients, sediment, pesticides, or excess salinity in impaired watersheds consistent wi th TMDLs where available” is a national priority to guide the allocation of resources.

## D. Program and Partnership Strategies

Technical Assistance Programs
DEP will provide technical assista nce to support watershed groups

, municipalities and others with local efforts to identify and fix NPS sources in their communities. This support will be provided through ongoing work including:

 Assist with volunteer training and provide technical assistance for locally

- funded watershed surveys, planning and impl ementation.

 Provide information to municipalities working on Comprehensive Plans and review plans for consistency and completeness.

 Promote long

- term, ongoing watershed stewardship through the use of the NPS Site Tracker and help partners and local groups use the tool.

 Provide technical manuals, information about grant opportunities and other available

resources. NPS Outreach Programs
DEP will build public awareness of NPS issues and promote positive actions through communication of the issues and solutions. In addition, DEP aims to provide partners and citizens with skills and expertise to implement BMPs to reduce NPS pollution. Actions include:

 Provide services and technical support for successful implementation of outreach efforts identified in WBPs, 319

- funded efforts and key partner efforts.

 Work with partners to promote effective outreach strategies based on principles outlined in
EPA’s Getting In Step: A Guide for Conducting Watershed Outreach Campaigns (2010).Maine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

65  Serve as a catalyst for more effective behavior change and BMP promotional outreach
efforts.

 Provide technical transfer, training opportunities and certification programs to key

a udiences utilizing the NPS Training and Resource Center.

 Develop and promote DEP online training modules to serve municipal NPS education and
assistance needs.

Partnerships Maine’s NPS program will b uild and strengthen partnerships at the program and pro ject level to maximize effectiveness and efficiency of NPS mitigation efforts. These partnerships will be fostered through numerous actions including:

 Establish a NPS Lead Agency workgroup that will meet twice a year to report on progress with implementat ion of the Maine NPS Management Plan and seize opportunities for
further collaboration.

 Continue to work with EPA and NRCS to carry out the National Water Quality Initiative in Maine. DEP will select a watershed and develop an assessment plan that collects data to evaluate the success of the work in the watershed in addressing the lake or stream’s impairment.

 Continue to c onduct the annual Watershed Roundtable to bring together watershed professionals to share information, network and collaborate.

 Continue to work with other government agencies to address and improve areas of environmental concern (e.g., impaired waters, compliance with instream flow and water level rules, fragile waters in need of protection, and a watershed approach).

319 Grant Administ ration Strategies

DEP will administer the Section 319 grant funds to comply with EPA program requirements and
h elp ensure success of statewide NPS programs and NPS watershed projects.

 Carry out priorities and commitments outlined in the EPA

- DEP Performance Partnership Agreement (e.g., GRTS reporting, annual reports , annual work plan).

 Conduct sub

- recipient monitoring according to program standard operation procedures.

 Administer the NPS grants program to meet fiscal management guidelines.

 Ens ure that at least 50 percent of the annual Section 319 award is allocated to implement accepted W BPs and the other funds are allocat ed for eligible NPS program activities

.

 Complete and close out all active grant projects within the contract period.Maine NPS Management Program Plan 2015

## I X

. F unding

Many sources of funding are available to conduct NPS assessment and mitigation work. Th ese include grants, loan programs, direct funding

, and in

- kind contributions. Many of these sources are highly competitive and have specific purposes and requirements. As a result, it is a significant challenge to garner the resources needed to restore and protect Maine’s vast water resources. Successful NPS mitigation efforts often leverage multiple funding sources and also work to raise ongoing funding from the local community. Some of the main NPS funding
sources are describe d in the following section.



## A. Funding Sources

Clean Water Act, Section 319 and 604(b) Grants DEP administers a competitive grants program using Section 319 and 604(b) funding from EPA to help communities identify NPS sources, prepare WBPs, and take action to reduce or prevent NPS pollution. Maine public organiz ations such as state agencies, Soil and Water Conservation

D istricts, regional planning agencies, watershed districts, municipalities, and nonprofit (501c3) organizations are eligible to receive grants. An annual RFP process offers grants for developing watershed plans and implementing projects identified in the plans. Local project sponsors are required to provide a mi nimum of a 40 percent match to the grant funds. Projects are typically
conducted over a two

- year period.

FMI

Clean Water State Revolving Fun d

As noted by EPA, t he CWSRF under Title VI of the Federal Water Pollution Control Act is the largest water quality financing source in the nation. Through the CWSRF program, each state and Puerto Rico maintain revolving loan funds to provide independent and permanent sources
of low

- cost financing for a wide range of water quality infrastructure projects. Funds to establish or capitalize the CWSRF programs are provided through federal government grants and state matching funds (equal to 20 percent of fede ral government grants). States may choose from a variety of assistance options, including loans, refinancing, purchasing, or guaranteeing local debt and purchasing bond insurance. States can also set specific loan terms, including interest rates from zer o percent to market rate, and repayment periods up to 30 years or the useful life of the project, whichever is less. States have the flexibility to target resources to their particular environmental needs, including polluted runoff from urban and agricult ural areas, wetlands restoration, groundwater protection , brownfields remediation, estuary management, and wastewater treatment. Additional information on the CWSRF program is available at http://water.epa.gov/grants_funding/cwsrf/cwsrf_index.cfm

In Maine, CWSRF funds nonpoint source projects through three different loan mechanisms; direct loans, pass

- through loans, and a linked

- deposit loans. In an effort to provide additional funding for private nonpoint source projects

, DEP expanded the traditional CWSRF direct loanMaine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

67 program into the other two loan programs. DEP and the Maine Municipal Bond Bank (MMBB) jointly admini ster the CWSRF. DEP administers the technical aspects of the program and project eligibility; the Maine Municipal Bond Bank (MMB) is the financial manager of the fund.

 Direct Loans

- Through direct loans from the CWSRF to municipal and quasi

- municip al

en tities, low interest funding is provided for NPS abatement projects. The DEP funds NPS projects for stormwater (e.g. tree gardens, infiltration basins, green roofs, bio

- swales, and
bio

- retention cells); the capping and other water

- quality related closure activities for non

discharging municipal landfills; and the covering of contaminated sand/salt storage areas.

 Pass

- Through Loans

- Ma i ne’s CWSRF has two pass

- through loan programs that provide low interest funding for private nonpoint source pollution con trols. Under these programs the
Maine’s CWSRF provides funding to other state agencies that in turn make low interest loans to private individuals for the projects.

The DEP i n partnership with the MMBB, the Finance Authority of Maine (FAME), and DACF,

i mplemented the Nutrient Management Loan Program (NMLP) for the construction of containment and handling facilities for manure and milk room waste. The NLMP program was recently expanded to fund NPS abatement projects that reduce or treat agricultural

runo ff, conserve irrigation water use, and reduce the impact of agricultural irrigation water withdrawals to stream flows and aquatic life by constructing irrigation reservoirs. The eligible projects now approved for funding align with agricultural NPS BMPs a nd projects need to comply with the Department’s Chapter 587: In

- Stream Flows and Lake and Pond Water Levels rule. Under this arrangement, the DACF will review the projects for program eligibility and ensure that the projects are completed in accordance w ith USDA Natural

Resources Conservation Service ’ s (NRCS) design criteria. FAME provides the low interest
loans to the borrowers.

In partnership with the MMBB and the Maine State Housing Authority, the DEP implemented the Septic System Replacement and Ove rboard Discharge Removal Loan Program to abate pollution from NPS decentralized wastewater treatment systems. Under this arrangement the Housing Authority provides the low interest loans to the borrowers.

 Linked Deposit Loans

– To provide these low intere st CWSRF loans

, the MMBB works with a private lending institution to fund the NPS control by accepting a reduced rate on a certificate of deposit (CD) investment and the lending institution agrees to provide a loan to the borrower at a similarly reduced ra te. The Maine Forestry Direct Link Loan Program provides incentive financing to loggers that reduce NPS pollution risk on timber harvests. This program, which works in partnership with the MMBB and the Maine Forest Service, provides low interest loans for silviculture best management practices.

Lake Stormwater Phosphorus Compensation Fee Program
Under the Maine Storm W ater Management La w, projects located in eligible lake watersheds may satisfy permit requirements for phosphorus reduction by paying a compensation fee into a Lakes Stormwater Phosphorus Compensation Fund for that same eligible lake watershed. The development project needs to be designed to provide at least 60 percent reduction in off

- site export of phosphorus required by the permit. The fee rate is $25,000 per pound of phosphorus. Compensation fund monies are used to implement Stormwater Compensation Projects to reduce pho sphorus export from existing high phosphorus export land uses in the lake watershed. DEP staff works annually with seven partner organizations to identify and implement phosphorus mitigation projects in these watersheds.

Local Funding Local funding is key to fixing NPS problems and is often the source of match required by grant programs. Since grant funding is limited, it can also be the sole source of funding for projects that are important to local community but that don’t fit in well with grant programs. Local funding can be in the form of in

- kind services or directed funding

, and come from municipalities, local organizati ons, private businesses

, and individual citizens. Given the high costs associated with some restoration projects, certain communities are also exploring and pursuing stormwater utilities and other ways to raise dedicated funds for watershed restoration

wo rk.

Maine Coastal Program Grants Towns and regional organizations in Maine’s coastal zone are eligible to apply for small grants through the Maine Coastal Program. The Coastal Communities Grant Program provides funds to towns and regional organizations fo r projects designed to improve water quality, increase resiliency and adaptation to erosion and flooding, conserve coastal habitat, promoteMaine NPS Management Program Plan 2015

Maine Natural Resource Conservatio n Program
The MNRCP was created to m anage the allocation of funds collected through DEP’s In Lieu Fee Compensation Program. This voluntary program allows entities that are impacting natural resources, primarily wetlands, to make a payment directly to the DEP as an alternative to the
traditio nal mitigation process. Fees collected by DEP are deposited in a Natural Resource
Conservation Fund administ ered by The Nature Conservancy. Public agencies, non

- profit conservation organizations, and private entities can apply through a competitive process , for funds to restore, enhance, preserve

, and create high quality natural resources throughout the State of Maine. Funding is available for land acquisition, habitat enhancement and restoration, and projects that restore watershed health.

Maine Small Community Grants Program The program provides grants to towns to help replace malfunctioning septic systems that are

po lluting a waterbody or causing a public nuisance. Grants can be used to fund from 25 to 100 percent of the design and construction costs, depending upon the income of the owners of the property, and the property's use. An actual pollution problem must be documented in order to qualify for funding. The highest priority is given to problems that are polluting a public drinking

water supply or a shellfishing area.

Natural Resource Conservation Service Programs
The NRCS carries out several programs that provide funding for conservation practices on agricultural lands. This includes the Wildlife Habitat Incentive Program (WHIP) t he Regional Conservation Partnership Program (RCPP) and Environmental Quality Incentive Program (EQIP). The EQIP program aligns especially well with NPS mitigation. EQIP is a voluntary program that provides financial and technical assistance to agricultural producers to help plan and implement conservation practices that address natural resource concerns and for opportunities to improve soil, water, plant, animal, air, and related resources. Projects located in watersheds selected through USDA and EPA’s Nat ional Water Quality Initiative are designated as high EQIP funding priorities. The NWQI is a national program started in 2012 that provides targeted EQIP funding to help farmers install practices to reduce water quality impacts in priority watersheds. States work with NRCS to identify focus areas and conduct assessment to track rest oration progress.

A. Measuring Environmental Success

The long term goals of Maine’s NPS program are:

 Restoration of Waters

- To restore the waterbodies which are impaired by nonpoint sources so that they meet water quality standards.

 Protection of Waters

- To prevent nonpoint source related impairme nts of unimpaired
waterbodies.

Evaluation of the effectiveness of Maine’s NPS program must be based on assessments that quantify the progress the program has made in restoring and protecting waters. Discussion of
evaluation s trategies associated with the two long term goals follows.

Restoring Waters DEP’s ambient water quality monitoring programs for lakes, rivers and streams, wetlands , and

marine waters provide the data necessary to evaluate success in restoring impaired waters. The Integrated Report reports the findings of monitoring and assessment programs.

 Lakes

- The large majority of lake impairments are due to violations of the lake trophic standards which state that lakes must be free of culturally induced blue green algal blooms and must have either stable or decreasing trophic states. The Maine Volunteer Lake Monitoring Program (VLMP) in combination with the DEP’s annual targeted baseline monitoring provide a strong data set for evaluating compliance with these standards. The combination of the VLMP’s bimonthly secchi disk readings and baseline sampling
chlor ophyll and phosphorus concentrations are very effective in detecting blue green algal blooms. This monitoring also provides a long term data set that can be used to monitor trends in a lake’s trophic state. Lakes that have been impaired due to the presen ce of blue green algal blooms are considered restored if they are free of blooms for at least five years out of the most recent ten year period. Additionally, trend analysis can show that even though a lake may still support occasional blooms, the water q uality is improving because the frequency and duration of blooms is decreasing. Lakes that have never supported algal blooms but are impaired due to a documented trend of increasing trophic state are considered restored when the long term data set shows a reversal of the trend.

 Rivers and Streams

- The most critical impairments of rivers and streams are violations of the aquatic life criteria. With the exception of the bacteria standards, all other water quality criteria have the goal of supporting aquatic life. The DEP’s Biomonitoring Program

86 terms of compliance with the aquatic life criteria. This evaluation indicates not only whether the river or stream segment in question meets the appropriate criteria for the segment’s class, but also what class’s criteria it does meet, if any. An impaired stream is considered restored if it meets its class’s criteria and is considered improved if it meets a higher class’s criteria than it had previously met. For instanc e, if a Class B stream segment historically had failed to meet even Class C criteria, but now consistently meets Class C criteria, it would be considered substantially improved. Assessment of impairments due to
violations of the bacteria standards are tre ated similarly. If long term monitoring indicates that the standard is being met, the segment is considered restored. If the frequency and magnitude of the violations is significantly reduced, it is considered improved.

 Wetlands

- The wetland monitoring program is relatively new, so the number of documented impairments is limited. Wetlands are also evaluated by the Biomonitoring Program and the means of determining restoration and/or improvement is parallel.

 Marine waters

- The mo st widespread impairme nt of marine water s are violations of bacterial standards for shellfish harvesting. Bacterial monitoring is done by several agencies including Department of Marine Resources t o determine shellfish closures, Cooperative Extension (Maine Healthy Beaches pro gram) and DEP.

Protecting Waters
The same data sets discussed above can be used to evaluate whether DEP is successful in preventing unimpaired waterbodies from becoming impaired. Simply stated, if no new waterbodies, particularly waterbodies that have historical records of meeting water quality standards, are added to the list of impaired waters, the State has succeeded in meeting this goal. If new waterbodies are added to the NPS impaired list, as will likely happen since many are considered threatened, evaluation of the success of protection efforts is more challenging. Program success must be based on an evaluation of how many waterbodies would have become impaired if preventative measures had not been taken. Evaluation of the success of protection efforts therefore requires not only documentation that degradation has not occurred, but also the more challenging quantification of the threat and the relative mitigation value of the protection measures that are taken. The mitigation value of protection measures can often be quantified through pollutant load reduction mode ls and similar metrics. It is much more difficult, if not impossible, to project the changes that would have happened in the receiving water, and particularly in its biological community, if for example, the pollutant loads
had not been reduced or the str eam corridor had not been protected. One of this Plan’s objectives is to develop metrics and methods to evaluate the effectiveness of protection

measures.

Defining Success As stated above, the long term goals of Maine’s NPS Program are to restore NPS imp aired waterbodies so that they meet applicable water quality standards and to prevent nonpoint source related impairments of unimpaired waterbodies. In most cases, attainment of the restoration goal is feasible, though in many instances it may take a long time and requireMaine NPS Management Program Plan 2015

87 commitment of a large amou nt of resources. The following discusses some of the particular challenges associated with restoring some lakes and urban streams, and the need to recognize not only the value of full restoration, but also the v alue of interim improvements in water quality and ecological condition.

The potential for restoration of impaired waters in Maine is influenced by a number of factors which must be considered when establishing realistic objectives. First, Maine’s Water Classification system is a goal oriented system that establishes high water quality standards. While the State aims to have its water meet those standards, it may not always be feasible to
do so , especially in the short term . For example, the trophic state standard for lakes requires that lakes have stable or decreasing trophic states and that they be free of culturally

- induced algal blooms that reduce water clarity below two meters. Meeting the first part of this standard, reversing a trend of increa sing trophic state, is almost always feasible and can be accomplished with a combination of BMP implementation for existing phosphorus sources in the watershed and the adoption of a program that minimizes the phosphorus inputs from new development in the w atershed. However, the second part of the standard, elimination of algal blooms, is not always feasible. This is because some algal blooms are fed not by phosphorus from the watershed, but by recycling of accumulated phosphorus in the lake’s sediments. While in these cases addressing NPS sources in the watershed can result in reduction in the intensity and duration of the algal blooms, it often cannot eliminate the blooms without measures being taken to directly control the recycling of phosphorus from t he bottom
sediments. Such measures include treatment of the sediments with aluminum salts and enhanced seasonal flushing of the epilimnion during the peak of the algal bloom. These measures can be prohibitively expensive, and though aluminum treatments n early always result in dramatic reductions in the intensity and duration of blooms, they may not always completely
eliminate blooms.

The aquatic life standard for streams presents some different limitations, particularly for urban
streams. When streams and rivers were originally classified in the 1970s and 1980s, the larger rivers with point discharges, for which much data had been collected, were classif ied with realistic goals. However, most smaller streams were given the default classification of B, unless they were located in pristine areas, in which case they were designated Class A or AA. This was appropriate in most cases, but in some urban and agricultural areas it may be unrealistic to expect the stream to be able to meet such a high aquatic li fe standard. If the only reason for the aquatic life impairment is the contribution of stormwater pollutants from the watershed, then attaining Class B standards is likely achievable through BMP retrofits, though it may be quite expensive. As is often th e case, if the stream and its corridor have been significantly altered through physical manipulations (e.g.

, straightening and widening, channel hardening, and filling of flood plains) or simply as a result of the greatly increased storm flows that the

str eam must pass, the habitat may be so compromised that even when the pollutant loads are attenuated, the stream may not be able to meet Class B standards. Fixing stream channel and corridor issues may not be technically feasible or may be prohibitively exp ensive.Maine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

88 In both of the cases cited above

– lakes with internal recycling of phosphorus and urban and agricultural streams with serious alteration of the channel and corridor

– it is always feasible to make the waterbody much healthier than it was. Even i f algal blooms cannot be completely eliminated, their intensity and duration can be greatly reduced, and the people who use and enjoy these lakes greatly appreciate the change. Pollutant load reductions, storm flow attenuation, and simple habitat restorat ion measures can result in significant improvements in the composition and structure of the biological community in urban streams, even though the community may not fully meet aquatic life standards. Though the goal is to have these waters meet standards, i t is important that the measures of success for the State’s NPS program not only recognize the value of restoring an impaired waterbody to fully meeting standards, but also appreciate the value of making significant improvements in an impaired water that enhance its ecological integrity and its value to the public when full restoration is not feasible

, at least in the short term

.

It is at least equally important to recognize the value of protecting threatened healthy waters so that they are not degrade d to the point of violating water quality standards. However, since the goal of protection is to maintain current good water and habitat quality, it is more difficult to document success of protection efforts. One cannot document that watershed protectio n efforts have been effective because a waterbody has not been degraded without assuming that changes occurring in the watershed would have resulted in degradation if the watershed protection measures had not been taken. Evaluation of the success of prote ction efforts therefore requires not only documentation that degradation has not occurred, but also the more challenging quantification of the threat and the relative mitigation value of the implemented protection measures. The mitigation value of protect ion measures can often be quantified through pollutant load reduction models and similar metrics. It is much more difficult, if not impossible, to project the changes that would have happened in the receiving water, and particularly in its biological comm unity, if, for example, the pollutant loads had not been reduced or the stream corridor had not been protected.

It is essential that the difficulties in documenting the success of protection efforts do not become a reason for lowering the priority that is given to protection. Many of the impaired streams in the State are in areas that have been urbanized relatively recently and were healthy resources two or three decades ago. There is no doubt that if protective measures had been
taken as these watershed s were developed that much of the degradation could have been avoided. The same pressures for urbanization are still in play, in other watersheds, so it is crucial that protection efforts be given highest priority or we will replace restored waters with

n ewly impaired ones. The effort required to restore a waterbody is always much greater than that required to avoid impairment.Maine NPS Management Program Plan 2015

## B. NPS Program Evaluation

In additio n to tracking progress with water quality restoration and protection goals, DEP will
conduct other program evaluation on an ongoing basis as required by EPA’s 319 guidance (EPA, 2013). The following reporting requirements will help EPA measure Maine’s progress in meeting annual milestones and NPS Plan success.

 Milestone Trackin g Database

– DEP will set up a database similar to one used by DEP for the PPG and use this database to track milestone progress and completion. Reports will be
submitted to EPA on an annual basis.

 Annual Report

– Since 2004, DEP has completed an annual NPS Program Report to report on NPS program activities, successes and completed grant projects . The report will be tailored to report on completed goals, objectives and measurable milestones from this Plan. Past annual reports are available at http://www.maine.gov/dep/water/grants/319

- documents/reports/

.

 Grant Reporting and Tracking System (GRTS)

– DEP will continue to enter program information into EPA’s GRTS database. Pollutant load reduction estimates resulting from project activities will be entered on an annual basis.

 Federal Financial and Performance Reports

– Annual financial and performance reports will be completed annually as required by 40 CFR 31.40(b)(1) and 31.41(b).

 Sub

- recipient Monitoring

- DEP will continue to monitor grantees using established Standard Operating Practices including annual Office Visits and site visits t o a subset of construction projects.

 Satisfactory Progress Determination

– DEP will provide information EPA needs to co n duct its annual progress and performance review under Section 319(h)(8).

 NPS Plan Updates

– Maine’s NPS Management Plan will be updated at least every five years. The next update will be prepared for 2020

## Appendix 2

- NPS Watershed Prioritization and NPS Priority Lists

Maine’s first NPS priority watersheds list was developed in 1989 and revised substantially in 1998. The list was updated as part of development of this NPS management plan. NPS impaired or threatened 5 waters with significant regional or statewide value were placed on the list. The list was developed t o help prioritize DEP NPS water pollution control efforts and attract local communities to take action to restore or protect waters impaired or threatened by NPS pollution. Since then, DEP has provided Section 319 grant funds for NPS water pollution contr ol projects with preference for projects in NPS priority watersheds. Most of the NPS projects proposed and selected under the annual competitive RFP have funded work to help restore or protect NPS priority watersheds.

In addition to the NPS Priority Wat ersheds List, there are several other lists that help guide MDEP efforts and regulatory programs. This includes the list of waterbodies with approved TMDLs, listed as impaired on the 303d list, listed in Chapter 502 Lakes Most at Risk from New Development , and Urban Impaired Streams. These lists will continue to be used for their respective purposes, and used to assist with the development of the prioritization criteria for NPS Priority List.



## A. Guiding Principles for Selection of NPS Priority Watershed s

The purpose of the priority list is to guide 319 NPS grant funds and assistance, and to encourage
NPS abatement work in these watersheds. The 199 8 NPS Priority Watersheds List was updated

as par t of this NPS Management Plan. Watersheds were evaluated using several guiding principles. As such, the first overall requirement is that NPS priority waters must have NPS pollution as the primary source of impairment or threat. Watersheds with point sources or legacy pollutants as the primary source of pollution were not selected as priorities since the point source or legacy pollutant would have to be addressed for water quality to significantly improve. Second, watersheds were evaluated for the likelihood that NPS grant funds and support could make a difference in the water quality. Another principle was to keep the extent of NPS priority watersheds reasonably focused so that the resources available to devote to control NPS pollution resources are invested where they are most nee ded and there is opportunity to effectively improve or protect waters vulnerable to NPS pollution.

The goal of developing the prioritization criteria was to make the selection as objective as possible, using monitoring data, analysis

, and reports. The pr iority lists of partner agencies and

5 The use of the term, ‘threatened’, in this document refers to un impaired waters that are subject to potential impacts from NPS pollution. The term is no t intended to be used as described in Maine’s Integrated Report, where waters are listed as ‘threatened’ for Clean Water Act §303(d) listing purposes if those waters are anticipated to fall

into non

- attainment with the ne xt listing cycle of two years.Maine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

93 organizations were used to assist with the prioritization process. There was also an effort to keep the NPS Priority Lists as focused as possible so that limited resources would not be spread
too thin and there would b e the best opportunity for restoring and protecting the highest priorities.

To determine the specific criteria to guide the evaluation of which watersheds should be prioritized, work groups consisting of DEP water resource professional staff

. S taff are knowledgeable in statewide lake, stream, or marine water quality and management issues and they reviewed available waterbody data and information. Partner agencies and regional monitoring organizations were also consulted in some cases. Specific crit eria were determined by waterbody type, and are listed in the table below and described in the following waterbody

specific sections.

## B. Updating the Priority Watersheds List

DEP

- Driven Updates DEP plans to evaluate ways to further improve the prioritization criteria as new evaluation techniques become available. For lakes, DEP plans to investigate incorporating sediment
aluminum content into the lake vul nerabi lity model. These data have not historically been available, but sediment samples have recently been collected from 250 lakes to analyze the

a luminum content. When these data are available, DEP will investigate its use to further
determine which lakes ar e threatened from further phosphorus input due to the low amount of aluminum in the sediment. For streams, DEP plans evaluations using the EPA Recovery Potential Screening Tool to assist with prioritization of impaired and threatened streams. For

marine waters, DEP will continue to investigate ways to improve the prioritization method as new data or methods becomes available. Additionally, DEP will add or remove waterbodies as new information becomes available, following the timeline for the annual publ ic opportunity.

Annual Public Input Opportunity There will be an opportunity annually for organizations and individuals to submit requests and supporting documentation for waterbodies to be added or removed from the priority lists. An
annual timeline wi ll be developed and announced.Maine NPS Management Program Plan 2015

## C. Lake Watersheds Prioritization

Impaired Lakes As a starting point, all lakes on the 2012 Integrated Water Quality Monitoring and Assessment Report Impaired List (Categories 4A: Impaired Use other than Mercury, TMDL Co mpleted; & 5A: Needing TMDLs) due to nonpoint source pollution were considered for inclusion on the priority list. Lakes on 2012 Integrated Water Quality Monitoring and Assessment Report Impaired List
due to hydrologic reasons (Category 4C: Impairment not Caused by a Pollutant) were excluded from the priority list. These lakes are impaired primarily due to hydrologic reasons, such as a major dam, and the hydrologic impairment. Lakes falling under this category are: Azi scohos Lake, Brassua Lake, Flagstaff Lake, Graham Lake, and Scopan Lake.

Several lakes were then removed from the priority list if they are believed to have a low feasibility for restoration due to having limited existing watershed development or legacy
nutrient accumulations in sediments. Lakes removed from the list for this reason are Arnold Brook Lake in Presque Isle, Lovejoy Pond in Albion, and Sewall Pond in Arrowsic.

96 Threatened Lakes Unimpaired lakes were assessed based on threats to water quality and value of the resource. Threatened lakes include lakes on the DEP Watch List, lakes having a recent or long

- term significant negative trend in water clarity, lakes determined as being sensitive to additional phosphorus inputs, and lakes having a recent increased threat to the watershed by development or agriculture. Lake value was designated as ‘high’ if a drinking water supply, if designated a priority water body b y a partner agency, or if determined to have outstanding water quality and being in need of protection. Lakes which had either a significant threat to water quality and/or significant value were added to the priority list. The details of these
selection criteria are below.

Unimpaired lakes were determined to have priority threatened lake watersheds if they met one of the following criteria:

 Listed on the DEP’s watch list . Lakes are included on the watch list if they were recently impaired and therefore still sensitive, or data suggests their water quality is near the impairment threshold.

 Licensed by the Maine CDC Drinking Water Program as a public water system with a lake a pond as the surface water source.

 Has a strong long or short

- term negative wat er clarity trend . This was determined by running the lake water clarity trend analysis model for lakes with s ecchi disk transparency readings for a significant number of years. The model was run for the whole dataset for each lake to determine the long

- t erm trend, and for the past 10 years for the short

- term trend. Data was needed for eight years or more to run the short term trend model. Results
of

- 0.5 or lower were deemed to be a significant negative trend. Lakes with a significant negative trend we re then further analyzed to determine if the negative trend was likely the result of a natural cycle or an overall shift in water quality. See the section below for a description of what was not included.

 Are sensitive to additional phosphorus inputs due to the lake’s hydrology and threats in the watershed. A lake was determined to be sensitive if DEP’s vulnerability modeling predicts the number of years for the lake’s phosphorus concentration to increase by 1 ppb is 25 years or less. The vulnerability model predicts changes in lake phosphorus concentration using watershed growth projections to estimate changes in phosphorus loading and the
1976 version of Vollenweider’s lake model to convert load to concentration. The model compensates for the influenc e of upstream lakes. If these sensitive lakes were determined to have watershed threats, they were then added to the priority list.

 Identified as a priority watershed by the Maine Natural Resources Conservation Service Environmental Quality Incentives P rogram ( EQIP ) National Water Quality Incentive or by

Maine Municipal Separate Storm Sewer System ( MS4 ) community plans.

 Having outstanding water quality in need of protection from threats in the watershed. The list of lakes with outstanding water qualit y was determined from review of long term water quality data. Lakes with outstanding water quality were added to the priority list if theyMaine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

97 were on 1998 NPS Priority List or their watershed was known to have a significant threat of development.

 Have rece nt increased impacts or significant potential threats from agriculture or development . This was determined through use of best professional judgment of the impact or significant threat of impact due to recent activities in the watershed. The sensitivity of the lake to more phosphorus inputs, extent and location of the agriculture or development, and cumulative effect of other watershed activities were considered in this determination. The Lakes added due to these criteria have had significant DEP involvem ent with the lake and the associated agriculture or development.

 Some lakes were not included on the priority list even if they met some of the above criteria due to the following reasons:

 The water quality data for some lakes with a significant negative water clarity trend (

- 0.5 or lower) indicated it was not indicative of a water quality shift . Each lake that had a long

- or short

- term significant negative water clarity trend was analyzed to determine if the negative trend was likely an overall negative shift in water quality or not. This was determined by analyzing any available water quality history data, including water clarity, phosphorus, chlorophyll, and dissolved oxygen readings. L akes having a short

- term negative trend as a result of water clarity returning to a stable state after drought conditions in the early 2000’s resulted in artificially ‘improved’ water quality, were not put on the priority list. Lakes whose negative trend were based on insufficient data or included multiple Secchi readings which hit the lake bottom were not put on the priority list.

 Lakes having a significant portion of their watershed protected either by being part of Acadia National Park or by having othe r watershed protection were also not included on the priority list, since there did not seem to be a significant threat.

 Small lakes (less than or equal to 50 acres) with limited existing watershed development were not included on the priority list, unless there was a compelling reason to add it to the list. Compelling reasons were if it is a public water supply, or has outstanding wa ter quality
and is in need of protection from threats in the watershed

## D. Stream Watershed Prioritization

Impaired Streams As a starting point, all rivers and streams on the 2012 Integrated Water Quality Monitoring and Assessment Report Impaired List due to nonpoint source pollution (Categories 4

- A: Rivers and Streams with Impaired Use, TMDL Co mpleted; 5

- A: Rivers and Streams Impaired by Pollutants
Other Than Those Listed in 5

- B Through 5

- D (TMDL Required); & 5

- B: Rivers and Streams Impaired for Bacteria Only, TMDL Required) were considered for inclusion on the priority list. To determine if a stream or river was impaired primarily due to NPS sources, the DEP water quality monitoring database (EGAD) was queried as to what were the major source s of the impairments. A stream was considered impaired primarily by NPS if the source s were listed as NPS, agriculture, stormwater, impervious surfaces, habitat modification, post

- development erosion and sedimentation, or source unknown.

Streams on 2012 Integrated Water Quality Monitoring and Assessment Report Impaired List which are expe cted to result in attainment (Category 4

- B: Rivers and Streams Impaired by
Pollutants

- Pollution Control Requirements Reasonably Expected to Result in Attainment) were not included on the priority list. These streams are believed to be impaired primarily due to

non

- NPS reasons, and are being addressed by regulatory programs and remediation work.

Streams on the 2012 Integrated Water Quality Monitoring and Assessment Report Impaired List
due to hydrologic reasons (Category 4

- C: Rivers and Streams with Im pairment not Caused by a Pollutant), mercury (Category 5

- C: Waters Impaired by Atmospheric Deposition of Mercury), or legacy pollutants (Category 5

- D: Rivers and Streams Impaired by Legacy Pollutants), were not included on the priority list. These streams are believed to be impaired primarily due to sources beyond the scope of the 319 NPS program.

Once the streams impaired by NPS were identified, they were determined to be priority stream watersheds if they met one of the following criteria:

 Had a Total Maximum Daily Load ( TMDL ) report completed or in development. This
includes streams with an individual NPS

- based TMDL and those included in the Maine Impervious Cover TMDL or Maine Statewide NPS TMDL (currently under development). These streams are impa ired primarily due to NPS pollution and the TMDLs provide an analysis of the causes of the impairment, and therefore a first step in determining what needs to be done to improve the water quality. For streams included in the Maine Statewide Bacteria TMDL, only those whose impairment was only due to bacteria that was not caused by a point source were listed as priority streams.

 Identified as a priority watershed by the Maine Natural Resources Conservation Service Environmental Quality Incentives Program ( EQIP ) National Water Quality Incentive, by

Maine Municipal Separate Storm Sewer System ( MS4 ) community plans, or by the Maine Healthy Beaches ( MHB ) program.Maine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

103  High risk of future development in watershed due to its location near a highway exit . These

stre ams were determined by completing a risk assessment of the likelihood of development
near each Maine Turnpike, Interstate 95

, and Route 295 exit that had stream watersheds within a one mile radius. Streams were categorized as having a high, medium, or low risk of development in their watershed due to Access

- related development. Streams with a high risk of development were added to the priority list.

 Some streams were not included on the priority list even if they met some of the above
criteria due to the following reasons :

o B elieved to be impaired due to ‘natural’ reasons such as being a backwater stream or having wetland effects which cause the stream to not meet its class.

o Streams or rivers impaired mostly due to legacy pollutants , particularly legacy

t oxins. It is believed that the legacy pollutants would have to be addressed in order for the stream to meet class, so addressing the NPS sources would not be sufficient to have it meet class and therefore the stream is not added to the NPS priority list.

o Large rivers (e.g. Kennebec River, Androscoggin River, Presumpscot River) were not included as priorities since the large size of their watershed makes measureable improvement in water quality due to implementation of NPS watershed based plans very unlik ely. Instead, tributaries to these larger watersheds were considered for the priority list based both on their own characteristics and their impact on the larger impaired watersheds.

o Rivers whose impairment is primarily due to point sources such as combi ned sewer overflows or wastewater discharges were also not included on the priority list. It is believed that the point sources would need to be addressed for the water quality of these rivers to be improved significantly.

Threatened Streams

Non

- impaired streams were assessed as to whether they are being significantly impacted or have the threat of significant impact from NPS pollution and whether the use of NPS 319 funds was likely to improve or protect water quality over the long term.

N on

- impaired streams were determined to be priority threatened stream watersheds if they met one of the following criteria:

 Streams listed on the 2012 Integrated Water Quality Monitoring and Assessment Report
‘Watch List’ Category 3 (Waters with Insufficie nt Data or Information to Determine if Designated Uses are Attained) for NPS issues. For streams, Category 3 is used as a ‘Watch
List’ for streams of concern. Included on this list are streams that were recently impaired,
and are therefore still sensitiv e, or if data shows it will likely be impaired in the future.

 Have recent increased impacts or significant potential threats from agriculture or development . This was determined through use of best professional judgment of the impact or significant threat of impact due to recent activities in the watershed. The sensitivity of the stream, extent and location of the agriculture or development, and
cumulative effect of other watershed activities were considered in this determination.

 Identified as a priorit y watershed by partner organizations, such as the Maine Natural Resources Conservation Service Environmental Quality Incentives Program ( EQIP ) National Water Quality Incentive, by Maine Municipal Separate Storm Sewer System ( MS4 ) community plans, or by the Maine Healthy Beaches ( MHB ) program.

 High risk of future development in watershed due to location near a h ighway exit . These streams were determined by doing a risk assessment of the likelihood of development near
each Maine Turnpike, Interstate 95

, an d Route 295 exit that had stream watersheds within a one mile radius. Streams were categorized as having a high, medium, or low risk of development in their watershed due to Access

- related development. Streams with a high risk of development were added t o the priority list.Maine NPS Management Program Plan 2015

107  E ven if streams or rivers met some of the above criteria

, they were not included on the priority list if they are l arge river s and/or the impairment is due to wastewater discharges

. For these streams or rivers it is believed that larger scale and/or point source

- related work is necessary and smaller tributary work is a better fit with the current NPS program.

## E. Marine Waters Watershed Prioritization Description

Marine areas were assessed on the impact or threat of NPS pollution, and the likelihood that NPS abatement work or support could make a short

- or long

- term improvement to water quality. The impact or threat was determined by whether there were impacted shellfish harvest areas of interest, beach closures, or documented negative water quality indicators. It was considered likely that NPS abateme nt work or support could be effective if the primary pollutant sources were nonpoint and non

- natural, and if the watershed likely had a significant water quality impact due to a low degree of flushing.

Impaired and Threatened Marine Waters 6 Unlike the lake and stream prioritization, the marine waters listed as impaired waters on the 2012 Integrated Report were not used as a starting point for the NPS Priority list. Marine waters have fewer numeric criteria and rely more on narrative criteria (i.e. best professional judgment). The 2012 Integrated Report impaired marine waterbodies list does not align geographically with the DMR shellfish harvest closure lists and it does not clearly distinguish between NPS and point source contributions. To keep prioritization criteria objective, the work group instead focused on data associated with bacterial closures and relied on data, knowledge, and priorities from other organizations. This resulted in a more exclusive and
smaller list for marine waters than for lakes and streams. Additions to the marine priority list are anticipated as more information becomes available.

Marine watersheds were added to the priority list if they met at least one of the following

criteria:

 Marine waters or beaches that M aine Healthy Beaches (MHB) has identified as likely areas with NPS sources of bacteria at levels that are concerning for primary contact recreation.

 Marine waters that the Casco Bay Estuary Partnership (CBEP) has identified with high/moderate value shellf ish beds, high/moderate harvester interest, and associated NPS sources documented in the CBEP report, Expanding and Sustaining the Shellfisheries of Casco Bay 2011 (2012).

 Marine waters associated with a Maine Municipal Separate Storm Sewer Program (MS4) priority watershed.

 Nearshore waters and intertidal clam flats where partners (e.g., CBEP, Friends of Casco Bay, Marine Environmental Research Institute, Wells Reserve) have documented water quality
indicators with suspected links to NPS pollution. Indica tors included documented eelgrass loss (only limited availability) or recurring macroalgae blooms, chronically high nitrogen

6 The use of the term, ‘threatened’, in this document refer s to unimpaired waters that are facing potential impacts from NPS pollution. The term is not intended to be used in the way described in Maine’s Integrated Report, w here waters are listed as ‘threatened’ for Clean Water Act §303(d) listing purposes if those waters are anticipated to fall

into non

- attainment with the next listing cycle of two years.Maine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

111 relative to comparable ambient conditions and/or chronically low dissolved oxygen (<5 mg/l).

 Marine waters that the Maine Departme nt of Marine Resources (DMR) has identified as having shellfish harvest closures related primarily to NPS threat, and that are protected embayments with limited assimilative capacity. Information available from sanitary surveys, watershed surveys, and loc al research and knowledge were used to determine if NPS threats were the dominant contributors to documented impairment or anticipated future impairment.

Some marine waters were not included on the priority list even if they met one or more of the
above criteria due to the following reasons.

 B elieved to have negative water quality indicators for ‘natural’ reasons , such as high bacteria from wildlife, or having low dissolved oxygen as a result of high sediment oxygen demand in shallow, productive, low f lushing coves.

 Believed to be impaired by legacy pollutants , particularly legacy toxics. If legacy pollutants would have to be addressed in order for the waterbody to meet class, then reducing NPS
sources would not be sufficient for attainment of standard s.

 Large or exposed estuaries, coastal embayments, or coastal shorelines with relatively high degree of flushing likely. The large scale of the area and influence of tides and surface currents make measureable improvement in water quality due to implementation of NPS watershed based plans very unlikely.

 Source of pollution is tied primarily to wastewater discharges, a small number of failing septic systems or overboard discharges , or other point sources . While failing septic systems and overboard dischar ges are in the realm of NPS, NPS grant program does not fund replacing sewage systems, so small watersheds with just a few septic issues are a better fit to be addressed by the town.

 Sources of pollution are not clearly of nonpoint origin

. M ore information on probable sources is needed in order for prioritization for NPS.

## Appendix 3

. Water Resource Monitoring and Assessment Strategies and Partners

A. Types of Water Quality Monitoring and Assessment

Monitoring and assessment work by DEP is conducted for a variety of purposes (Table 23 ). Much of DEP’s monitoring and assessment work is conducted to determine if the State’s
waterbodies meet th eir designated classification. Other types of monitoring are also integral to the NPS program. Water quality probl em identification and assessment of conditions is needed to target NPS program efforts. T he methods, scale and the expertise needed to carry out monitoring and assessment depends on the objective, such as ambient water quality monitoring, development of a new assessment tool, stressor analysis, or determining the sources of pollution

## B. Monitoring and Assessment for Different Types of Waters

Rivers and Streams The DEP assesses the water quality of rivers and streams primarily through its Biomonitoring Program on a 5

- year rotating basin schedule. The Program has had a macroinvertebrate biomonitoring program for 30 years and more recently began an algal biomonito ring program. Stream macroinvertebrate communities are assessed using a statistical model that predicts the likelihood of a waterbody attaining the aquatic life criteria of its assigned class of AA/A, B, or C.
Numeric biocriteria that describe the macroi nvertebrate classification decision process were adopted into rule (Chapter 579) in 2003. Biological assessment methods and statistical model for algal communities have been completed, but not yet implemented. The algal data is however being interpreted to determine narrative aquatic life criteria for the integrated report.

The primary causes of impairment for rivers and streams are toxic contamination, non

attainment of aquatic life criteria, oxygen depletion, nutrients and pathogens. Toxic

contami nation, which includes legacy pollutants such as DDT, dioxin and PCBs accounts for the greatest number of impaired miles. Non

- attainment of aquatic life criteria impairs 408 miles, oxygen depletion 464 miles, and pathogens 175 miles.

The impairment sour ces are about equally divided between industrial point source discharges, unknown sources, and non

- point sources with each affecting approximately 400 river miles. The primary non

- point sources are agricultural affecting 358 river miles and development an d urban stormwater affecting 199 river miles. (Source: 2012 Integrated Water Quality Monitoring and Assessment Report)

The Volunteer River Monitoring Program (VRMP) provides technical support and resources to a network of volunteer groups. Currently ther e are nine watershed groups throughout the State that are part of the VRMP Program. In 2012 monitors covered an area of over 1,000 square miles of watershed, monitored 82 sites and completed 478 sampling events. Data collected included temperature, disso lved oxygen, conductivity, bacteria, turbidity and total suspended
solids.

Wetlands DEP’s Biological Monitoring Program is primarily responsible for monitoring and assessing wetlands. In 1998, DEP began developing a biomonitoring program for wetlands which focuses on emergent and aquatic bed wetland habitat, including freshwater lacustr ine and riverine fringe wetlands. Monitoring includes biological monitoring for macroinvertebrates, algae, and phytoplankton. In addition, ecological conditions are documented and a rapid assessment of stressors completed. A model that assesses freshwa ter wetland macroinvertebrate communities to predict attainment of tiered aquatic life use criteria in Maine’s water quality standards has been completed, but not implemented. The data are being interpreted to determine narrative aquatic life criteria f or the Integrated Report.

The primary causes of wetlands impairment are toxic contamination and benthic macroinvertebrate bioassessments accounting for 761 and 273 impaired acres respectively.Maine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

116 Sources of impairment are point and nonpoint sources (primar ily agriculture, development and urban stormwater).

Lakes Monitoring and assessment of lakes is achieved primarily through the Maine Volunteer Lake Monitoring Program. Most of the water quality data is collected by volunteers and associated lake organiz ations/regional entities as described in the previous “Monitoring and Assessment Partners” section. The DEP Lakes Assessment Unit staff also undertake targeted and probability

- based monitoring on a statewide basis annually.

The causes of impairment are dissolved oxygen, total phosphorus, secchi disk transparency, habitat assessment, and turbidity. The sources of impairment are mostly nonpoint sources. This includes agricultural sources affecting 16 lakes and development/urban stormwater affecting 27 l akes. Other sources of impairment include flow alterations and regulation, land treatment, landfills, internal recycling, and natural sources.

Estuaries/ Marine Waters Monitoring and assessment data for marine waters comes from a variety of sources to incl ude DEP, other government agencies, academic institutions, non

- profit organizations, and municipalities. DEP monitoring of toxic contamination is assessed using data collected through the DEP Surface Water Ambient Toxics (SWAT) program and the Gulf of Mai ne Council on the Maine Environment’s Gulfwatch project. The SWAT program analyzes blue mussel, softshell clam, and American lobster tissue as indicators of toxic contamination affecting human and ecological health. DEP also contributes to the Gulfwatch Contaminants Monitoring Program which is part of the Gulf of Maine Council on the Marine Environment. Mussels collected through this program are analyzed for heavy metals, mercury, polycyclic aromatic hydrocarbons (PAHs), PCB cogeners, and organochlorina ted pesticides. Bacterial monitoring is done by several agencies including DEP for TMDL monitoring, DEP

- Cooperative Extension (Maine Healthy Beaches program) for swimming beach quality, and Department of Marine Resources
to determine shellfish closures.

Causes of impairment include bacteria, low dissolved oxygen, nutrients, and other biological indicators of eutrophication and toxics. Bacterial contamination is a significant cause of impairment, affecting 159 square miles of estuarine waters (not includi ng CSO affected waters).

To xics is also a primary cause of impairment (lobster tomalley consumption advisory)

. Sources of toxic contamination include industrial loads for dioxin, and for some harbor areas past activities have left dioxins, pesticides, me tals, and PCBs. More recent toxic contamination originates from several sources. These sources include urban development (PAHs and metals),

Groundwater
The DEP, DHHS Division of Environmental Health, DACF Maine Geological Survey, and the U.S Geological Survey share responsibility for the protection and assessment of groundwater. Groundwater monitoring consists of two types of monitoring, site

- specific or generalized. Most

gro undwater data is site

- specific and is gathered as part of permit conditions, enforcement, orMaine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

117 impact assessments. General ambient monitoring is done by the Maine Geological Survey and U.S. Geological Survey. These two agencies monitor changes in water qua lity and quantity through a network of observation wells. DHHS also maintains a database of public water supply well water quality data.

Maine’s groundwater efforts emphasize resource protection through three efforts. These are coordination of groundwa ter programs, assessment of protection problems that include enhancement of the Environmental and Geographic Analysis Database (EGAD), and increased groundwater protection and risk reduction.

Assessment of groundwater impairment is not currently done as part of the DEP “Integrated Report” assessment. Contamination however likely threatens a significant area of Maine’s groundwater in developed areas of the State. Nonpoint source pollution is responsible for most groundwater pollution. Primary sources ar e agriculture, hazardous substance sites, spills, landfills, leaking underground storage tanks, septic systems, and shallow well injection.

. Collaborators and Partners

Much of the water quality data that is collected and assessed for the integrated report is collected through DEP monitoring programs. However, data are also provided from numerous other agencies, organizations and volunteer monitoring groups. Data collec ted by volunteer monitoring groups or conservation organizations must meet quality assurance/quality control requirements to be accepted by DEP. Volunteer groups that are part of the Maine Lake Volunteer Monitoring Program or Volunteer River Monitoring Pr ogram work under a Quality Assurance Project Plan and their data is directly managed by DEP. Conservation groups not under the umbrella of one of these programs must have an EPA approved QAPP or Department approved sampling plan.

## Appendix 4

. Targeted Assessment and Stressor Analysis

The success of restoration and protection efforts hinges on understanding the environmental stressors that are causing or could cause the impairment, and the watershed conditions that are generating those stressors. The purpose of this step is to inform t he development of an effective watershed based plan by identifying and characterizing the relevant stressors and watershed conditions. The information required to accomplish this varies with the waterbody type and in many instances, whether or not the wate rbody is impaired.



## A. Lake Watersheds

The water quality standard that is most likely to be violated in lakes and ponds is the trophic standard, which states that lakes and ponds (a) shall have a stable or decreasing trophic state, subject only to natura l fluctuations; and (b) shall be free of culturally induced algal blooms which impair their use and enjoyment. Since the limiting factor for algal production in Maine lakes is the concentration of phosphorus in the water, the stressor of most concern for lakes is phosphorus loading. Hence, assessment efforts are focused on evaluating the lake’s trophic state; characterizing important current and potential phosphorus sources to the lake from both the lake’s watershed and its bottom sediments; and, as spec ifically as possible, identifying opportunities to reduce phosphorus loading to the lake.

 Water Quality

- Each year DEP’s Lake Assessment Section, in combination with volunteers in Maine’s Volunteer Lake Monitoring Program, collect information on the trop hic state of many of the State’s developed lakes. The data are used to evaluate the stability of trophic state in each lake; the incidence of algal blooms; and, especially in cases of lakes with increasing trophic state or algal blooms, the amount of phos phorus being recycled into the
water column from the lake’s bottom sediments.

 Watershed Surveys

- The method most often used to identify watershed phosphorus sources is the Lake Watershed Survey, in which volunteers, under the guidance of professionals, c anvas the watershed to find specific, usually stormwater

- related sources of phosphorus (e.g. unstable roads, eroding ditches, agricultural operations). The identified sources are then evaluated by professionals for the severity of the problem and the prob able cost of repair, creating a very specific prioritized list of opportunities to reduce phosphorus loading to the lake.

 Internal Recycling Evaluation

- Ongoing evaluation of the lake’s trophic state and a watershed survey that identifies opportunities t o reduce phosphorus load to the lake are likely the only assessment efforts that will be used if the lake currently meets trophic standards. If the lake does not meet standards, assessment is likely to include intensive monitoring of the phosphorus mass i n the water column over the period from May through September, and also the phosphorus, iron and aluminum content in the bottom sediments.Maine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

120 The purpose of this monitoring is to quantify the amount of internal recycling of phosphorus from the lake’s bottom sediments.



## B. Stream Watersheds

Stream watersheds typically present more complex challenges than lakes, especially if they are in urban settings and the aquatic life standard is violated or threatened. In Maine, each Class of
river and stream has an aquatic life standard that describes the health of the biotic community that the stream must achieve. For Class AA and A streams, the community must be as naturally occurs; for Class B streams, the stream must support all indigenous aquatic species withou t detrimental change to the resident biological community; and for Class C streams, the stream must support all indigenous species of fish and the structure and function of the biological community must be maintained. There are many stressors that can cau se or contribute to violation of this standard, so effective restoration and/or protection requires identification of which stressors are most important, or could become important, for any given stream situation. Given this, the suite of water quality, bi ological condition, habitat, stream corridor and watershed assessment tools employed varies depending on the condition of the stream and its watershed, and which stressors are most likely to contribute to impairment of the community.

Stream Re storation

S everal different assessment tools are utilized w hen the stream in question is impaired, and particularly when the stream fails to meet its aquatic life standard . In most cases the assessment work is performed by several entities, with some elements done b y DEP staff and others by the municipality, their consultants, or other local partners.

 Water Quality

- Water quality is always monitored to some degree, and usually includes a
mix of base flow and storm event mo nitoring at several stations. Typical p arameters include temp erature, dissolved oxygen (DO) , specific conductance, chloride, phosphorus, heavy metals and hydrocarbons. Rising stage samplers are often used during storm events, and data sondes routinely used to obtain continuous m easurements of temperature, DO and specific conductance. In order to focus in on discrete sources, conductivity screening, where many measurements are taken along the stream, may also be used

.

 Biological Assessment

- As part of the DEP’s ambient water quality assessmen t program, biological assessments of the macroinvertebrate and the periphyton communities are made to define the impairment. There is often a signature in the community composition that indicates which stressors are in play and this can influence the dire ction in which other assessment efforts are focused. Biological assessments usually continue at regular intervals throughout the restoration process to assess effectiveness.

 Stream Habitat and Corridor Assessment

- In

- stream habitat and the condition of the
stream corridor are also usually evaluated. Various habitat assessment and riparian
corridor assessment tools are used and often volunteers assist in these assessments. This helps local citizens become familiar with the issues affecting their stream. Habitat conditionMaine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

121 is characterized and areas where habitat is damaged are identified. Bank stability, flood plain integrity and the condition of riparian vegetation is also assessed. In cases where the stream receives excess storm flow from impervious surfaces in the wate rshed or where historic alterations have affected habitat integrity or flow regime, a fluvial geomorphological assessment is performed. This assessment describes the processes that are dominant in each reach of the stream channel, identifies and character izes areas of channel instability, provides direction for watershed storm flow management and identifies opportunities for in stream habitat improvement projects.

 Watershed Assessment

- Targeted assessment always includes some level of watershed

assessmen t. It is important to understand where the water in various reaches of the stream comes from and what it comes into contact with on its way to the stream. In urban settings, it is often necessary to map the drainage infrastructure in order to accurately map the boundaries of the watershed, as well as the boundaries of catchments that drain to each stormwater outfall. Analysis of land use, particularly imperviousness, in each outfall catchment is helpful when identifying and prioritizing BMP retrofit oppo rtunities in the watershed. In addition to watershed mapping, watershed surveys are often employed, sometimes using volunteers. The types of sources surveyed will vary depending on the dominant land uses in the watershed and which stressors are likely co ntributing to the impairment. In a rural impaired watershed, agricultural hotspots might be the focus of the survey, while in an urban setting hotspots such as road intersections, gas stations, and high

turnover parking areas may be the focus.

Stream Pr otection When the stream in question is threatened but not yet impaired, the assessment regime is usually limited and aimed at (a) ongoing evaluation of the biological community to insure it continues to meet appropriate aquatic life standards and (2) identifying the stressors most likely to become issues in the watershed. The latter is often accomplished with conductivity screening and continuous measurement of temperature, dissolved oxygen and specific conductance with data sondes and loggers. Strea m corridor and habitat assessments may also be performed, with particular emphasis on identifying areas critical for riparian protection. A limited watershed survey may be performed to identify opportunities for retrofits of existing sources, but the main focus of assessment is often to guide development of local policies, ordinances, practices, and infrastructure improvement strategies that can be incorporated into an effective watershed protection plan.



## C. Marine Watersheds

Coastal watersheds demonstrate considerable diversity in physical, chemical, and biological characteristics as they encompass estuarine waters ranging from barely measurable salinity to fully saline seawater in marine areas. Marine waters are influenced to vary ing degrees by
freshwater inflows from rivers and streams as well as marine waters during flood tides and periods of offshore wind. Urban settings and large watersheds provide different sources, types, concentrations, and mechanisms of pollutant loading t han do rural settings or smallMaine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

122 watersheds. Additionally, characteristics of biological communities in marine waters differ based on tolerance to the physical and chemical environment. Because of this diversity, and also the variety of standards that may apply in certain situations, assessment strategies for

marine waters will vary depending on the nature of the impairment or threat.

 Shellfish closures

- The Maine Department of Marine Resources’ Shellfish Growing Area Program determines shellfish growing area classifications in all shellfish harvesting areas to ensure that only pollution

- free areas are open to harvesting. Classifications are set through sanitary surveys that include a shoreline survey to identify pollution sources that may impact water q uality; marine water sampling to determine fecal coliform bacterial levels in
the marine water; and analysis of how weather conditions, tides, currents, and other factors may affect the distribution of pollutants in the area. Water samples are collected mo nthly from January through December. DMR sanitary surveys have identified NPS pollution as the likely sources of bacterial contamination in numerous shellfish harvesting areas in the state. DMR’s assessments are supported and complimented by a number of other organizations including the Casco Bay Estuary Partnership, the Friends of Casco Bay, the Marine Environmental Research Institute, the Wells Reserve, the Maine Clammers Association and many of the coastal municipalities.

 Contact Recreat ion

- T he Maine Healthy Beaches Program is a partnership between the University of Maine Cooperative Extension/Sea Grant, DEP, and local municipalities that brings together communities to perform standardized monitoring of beach water quality and notifies the public if health risks are detected. In cases where repeated. Each year the program selects a few beaches with chronic bacterial contamination do supplemental assessments to identify the source of the contamination. These “special projects” incorporate severa l assessment tools including circulation studies, bracket sampling for bacteria and whiteners, and in rare cases, microbial source tracking.

 Algal Blooms

- I n recent years there have been an increasing number of localized blooms of the macroalgae

, Ulva (f ormerly Enteromorpha.spp

, on coastal mudflats. These blooms can be detrimental to the native biological community. In some instances the blooms are fed by land

- based nutrient sources from the watershed that drains to the flats. Assessments
similar to t he lake watershed survey can be effective in identifying the likely sources of nitrogen and/or phosphorus that are driving the blooms.

 Other Impairme nts of the Biological Community

- A s with rivers and streams, each class of
estuarine and marine waters ha s narrative biological criteria. The criteria are the same for the marine Classes SA, SB and SC as they are for the riverine Classes A, B and C respectively. There are many different stressors that can cause a biological impairment so assessment strategi es must be aimed first at identifying the stressors responsible for the impairment and next, at identifying the watershed conditions that are contributing to the impairment.
When the marine waterbody in question is impaired, threatened, or in need of prot ection, many different assessment tools and methods may be employed. These include waterMaine NPS Management Program Plan 2015

- 2019 ( September 15, 2014 ) Maine DEP

123 quality monitoring, biological assessments habitat assessments and source identification. Additionally, comparisons with historical data may indicate meaningful chang es over time, and local knowledge of landowners, municipal officials and fishermen can inform site selection and focused study. Furthermore, knowledge of waterbody characteristics can help to identify comparable waterbodies for use as reference.

 Water Q uality

- M onitoring effort s generally consists of measurement of temperature, salinity, D.O., pH, turbidity, chlorophyll a throughout the water column, water clarity, inorganic and total nitrogen, and phosphorus in the surface water. In the water column, light attenuation and organic nutrients, including carbon, can also be monitored to address specific research questions. Studies of sediments may include chemistry of pore water. Data sondes and sensors used discretely or unattended, permit acquisition o f the above data types, and chemistry is completed with grab samples analyzed by qualified labs.

 Biological A sses s ments

- Assessments of b enthic floral and faunal communities assist in characterization of the impact on the resident biological community an d can demonstrate communities where invasive species could dominate. Biological community assessments can include inventorying the distribution, abundance, and density of individuals as well as species and higher order level diversity of marine macrophyte s (seagrasses, macroalgae), epifauna, and infauna. Presence and proliferation of particular organisms, especially those in areas of chronic or temporal high temperature, low pH, hypoxia or anoxia, and persistent nutrient or pollutant loading can indicate biological responses to stressors that support impairment of numeric or narrative criteria. The absence or low abundance and diversity of particular species can similarly indicate the influence of stressors.

 Habitat A ssessments

- Habitat assessments a ssist in determining suitability of water or sediment for the native biological community. Characterization of habitats can include chemical analysis of water or sediment pore water, particle size analysis, habitat complexity, and in

- water structure inclu ding man

- made (e.g. docks, anchors and mooring buoys) and natural features (e.g. cobble and boulders, macrophyte substrate). Mapping of habitat types relative to watershed characteristics and point and NPS influences can also explain sensitivity of habita ts to change based on suspected anthropogenic influences. Degraded habitat is often identified by hypoxic or anoxic and acidic waters, surface sediments with high sulfide concentrations and corresponding bacterial community, scarring from dragging or eros ion, fragmented macrophyte distribution with a high occurrence of invasive species, or the absence of life.

 Pollution Source Evaluation

- Targeted assessment also includes some evaluation o f watershed, offshore, and atmospheric influences to determine rel ative contributions of pollution sources . Watershed influences consider location and intensity of adjacent and upstream land use, change over time in land uses, minimization of impacts and use of BMPs, seasonal and year

- round population, and proximity of point source discharges and their effluent quality and quantity. In

- water influences consider extent of tidal magnitude and associated flows, and size and type of inflows, whether regulated or naturally flowing.Maine NPS Management Program Plan 2015
