Set of actions that are designed to achieve the TMDL by reducing nutrient loading Implement the PCS through regulation although the components may be a combination of voluntary and required actions The “Tributary Action Team” recommends the PCS to the Department for promulgation What is a Tributary Action Team?:  What is a Tributary Action Team? A group of citizens With varying interests, concerns, knowledge and beliefs Who meet with the purpose of recommending a Pollution Control Strategy to the Department Why Tributary Action Teams?:  Why Tributary Action Teams? Involve all members of the community Gain the perspectives and knowledge of the people likely to be impacted by the PCS Have the public recommend a PCS with which they are willing to comply Public Talk—Real Choices:  Public Talk—Real Choices Move the formulation and creation of a major public policy from the agency to the public Deliberation and Dialogue “Front-load” the public in the process Public Talk—Real Choices:  Public Talk—Real Choices Organize a Team Education Issue Framing Evaluate Issue Framework Public Forums Recommendations Inland Bays TAT History:  Inland Bays TAT History Convened by Center for the Inland Bays Joined with TMDL Advisory Committee Sent three sets of recommendations for the PCS to DNREC Addressed wastewater, development, stormwater Silent on agriculture IB-TAT & Agriculture:  IB-TAT & Agriculture Beginning of TAT process also beginning of discussion on the Nutrient Management Act Agriculture was taken off the table No consensus on BMP efficiencies Need to account for Ag progress Needed an agriculture component to the Strategy PCS Workgroup:  PCS Workgroup Members from various agencies DNMC staff DNREC: DWR & DSWC NRCS Sussex Conservation District Kent Conservation District University of Delaware Cooperative Extension Mission: To devise a method to estimate how existing agricultural practices have already contributed to achieving the TMDL-mandated nutrient load reductions … PCS Workgroup Decisions:  PCS Workgroup Decisions Calculations/recommendations based on best available science Averages from several studies and/or ranges Dependent on weather and site specific conditions A lag time (1-40 years) likely exists between practice implementation and surface water quality improvement Nutrient Management Commission Decisions:  Nutrient Management Commission Decisions Concurred with Workgroup decisions on BMP efficiencies Endorsed concept of Ag BMP goals in PCS Recognize the enormous contributions that Agriculture has made toward reducing nonpoint source pollutant loadings to the Inland Bays Everyone needs to do their fair share The PCS Document:  The PCS Document Progress to date Point source Nonpoint source Recommendations for future actions How the PCS should achieve the TMDL Costs Implementing Organizations Point Source Progress to Date:  Point Source Progress to Date 13 sources to be eliminated 7 eliminated 1 trade (Vlasic/Pinnacle Foods) 5 sources remain Point Source Progress to Date:  Point Source Progress to Date 7 eliminated Delaware Seashore State Park Frankford Elementary School Colonial East Mobile Home Park Townsend’s (2 sources) Delaware State Housing Authority Georgetown Wastewater Treatment Plant 1 trade (Vlasic/Pinnacle Foods) 5 remaining NRG/Conectiv/DP&L Bayshore Mobile Home Park Permit exp. 2005 Lewes Wastewater Treatment Plant negotiations Millsboro Wastewater Treatment Plant Exploring alternatives Rehoboth Wastewater Treatment Plant Consent decree Point Source Progress:  Point Source Progress Point Source Progress:  Point Source Progress 82.5% 8.5% NPS Progress to Date—Agriculture:  NPS Progress to Date—Agriculture NPS Progress to Date--Wastewater:  NPS Progress to Date--Wastewater 16,534 OWTDS on central sewer 90% removal efficiency for Wolf Neck 100% efficiency for South Coastal Total 517 lb/day TN & 37 lbs/day TP removed $9.8 million/year or $52/lbTN removed Or $8500 per system NPS Progress to Date--Wastewater:  NPS Progress to Date--Wastewater Holding Tank Inspection Program 182 holding tanks Pumped 12 times/yr 14 lb/day TN & 4.6 lb/day TP removed $92/lb TN removed or $2,550/system/yr NPS Progress to Date—Stormwater:  NPS Progress to Date—Stormwater Implementation of Sediment and Stormwater Law 130 acres treated 22 lb/day TN & 1.5 lb/day TP removed $62-313/lb TN reduced NPS Progress to Date:  NPS Progress to Date 26% 60% Average Cost/lb of All BMPs Implemented to Date:  Average Cost/lb of All BMPs Implemented to Date Costs to Date:  Costs to Date The POLLUTION CONTROL STRATEGY Recommendations:  The POLLUTION CONTROL STRATEGY Recommendations Guiding Principles Point Sources Nonpoint Sources Agriculture Urban/Suburban Wastewater Stormwater Concurrence Guiding Principles:  Guiding Principles A public policy of incentives, when strengthened with the threat of regulation, should allow people to innovate within their own financial constraints. Education needs to be applied “across the board” with emphasis on the younger generation. Be able to adapt to changes in scientific knowledge, but not allow the need for scientific certainty to prevent action from taking place immediately. Guiding Principles:  Guiding Principles Recognize the need for experts and professionals as well as the need for community participation in the development and implementation of policy. Cost-benefit analyses are important tools, yet they should be used efficiently, within bounds, and not as delay tactics. Recognize the importance of “political players” in accomplishing Pollution Control Strategies. People want to know where their tax money is being applied. Point Sources:  Point Sources Systematic elimination To require the elimination of waste loading into the affected waterbody by point sources on a firm, fixed schedule as approved by the Department. This elimination must occur within five years of the expiration of the facility’s current NPDES permit unless a longer period of time is provided for in a State or Federally enforceable Consent Order, Decree, or Administrative Order. Water quality trading available as an option 2:1 ratio Must achieve the NPS reduction before can generate credit Agriculture Implementation Goals:  Agriculture Implementation Goals Full compliance with NMA VOLUNTARY Maintain existing BMPs Continue use of phytase and other feed amendments Minimize land taken out of production BMP goals would remove less than 7% of agricultural lands from production Least cost of all nonpoint source BMPs; most “bang for the buck” Agriculture Implementation Goals:  Agriculture Implementation Goals 39,105 acres of cover crops (annually) 1,630 acres in forested buffer 1,630 acres restored as wetlands Add an additional 50 storage/compost structures Increase the manure relocated to 21,730 tons Treat an additional 450 acres with water control structures Slide35:  Agriculture PCS Slide36:  Agriculture PCS Slide37:  Agriculture PCS Slide38:  Agriculture PCS Urban/Suburban:  Urban/Suburban Voluntary The Strategies for State Policies and Spending and other incentive/disincentive tools should be specifically tied to natural resource protection goals in the Inland Bays Watershed. Develop a program that addresses practices that may result in nutrient reductions on parcels of 10 acres or less where nutrients are applied. These shall include, but are not limited to: establishing nutrient budgets for homeowners, technical support for small landowners, and education. Urban/Suburban:  Urban/Suburban Regulatory Designation of the Inland Bays Watershed as a ‘Critical Environmental Area.’ The entire Inland Bays Watershed shall be managed for nutrient reductions consistent with TMDL load reductions, or reductions attributed to ‘best available technologies’ (BATs). Open space shall be managed to reduce nutrient loading. Urban/Suburban:  Urban/Suburban Regulatory Upon the development of a parcel, a nutrient budget must be produced. The nutrient budget must illustrate that the future land use will reduce nutrient loading by the percentage required by the TMDL for the waterbody in which watershed the particular location exists (or uses all available BMPs). The Department shall not issue any permit for a parcel or project unless a submitted and approved nutrient budget shows that the parcel or project will achieve the TMDL-required nutrient load reduction (or uses all available BMPs). Require urban/residential riparian buffers of 100 feet from all perennial and intermittent streams. Nutrient Budget:  Nutrient Budget Protocol designed to evaluate the impact of a land use change on nutrient loading Based on the use of best management practices, their nutrient reduction efficiencies, and land use loading rates based in scientific literature Piloted during the PLUS process Use is required before release of any DNREC permit Non-Agricultural Buffers:  Non-Agricultural Buffers Only for NEW developments Tier 1 50’ closest to water or wetland Vegetation requirement (trees) Tier 2 25’ from outer edge of Tier 1 Vegetation requirement (trees, shrubs) Tier 3 25’ from outer Tier 2 Vegetation requirement (trees, shrubs, or grasses) Allows for an average of 100 feet as long as 80% meets a minimum of 50 feet Wastewater:  Wastewater Voluntary Sussex County converts an additional pre-existing 5,000 individual onsite systems to central sewer. 100% efficiency for South Coastal Total 170 lb/day TN & 12 lb/day TP removed $60/lb TN removed Or $10,000-11,000 per system Or $657/system/yr Economic assistance for those in need will be available through the Financial Assistance Branch, Division of Water Resources. Wastewater:  Wastewater Regulatory The DNREC, Division of Water Resources, Ground Water Discharges Section shall implement a compliance and inspection program for individual onsite wastewater treatment and disposal systems in order to enforce existing requirements that the associated tanks be pumped every three years by a licensed liquid waste hauler and that alternative systems are maintained in accordance with manufacturers’ specifications. Proof of pump-out at property transfer Permanent holding tanks shall not be permitted within the watershed. A permanent holding tank is a tank that will be in use for 4 years or more. Maintain the existing Holding Tank inspection program. Wastewater:  Wastewater Regulatory All new or replacement on-site wastewater disposal systems must be designed to achieve performance standards as specified in the PCS regulation. These standards vary based on system size. In addition, all existing functional systems must be retrofitted in accordance with the performance standards within 15 years of the promulgation of the PCS regulation. Systems in compliance with inspection requirements and standards, which are slated to be connected to central sewer within this same time period, will be exempt from this requirement. Performance Standards:  Performance Standards Tiered based on system size Nitrogen based Provision for requiring Phosphorus standards Built-in inspection Ability for property owner to select a system “off the shelf” or to work with an Engineer Performance Standards:  Performance Standards Nitrogen Tiers PSN1 20,000 gpd or larger 5 to 8 mg/l PSN2 Between 2,500 and 20,000 gpd 12.5 mg/l PSN3 Less than 2,500 gpd 20 mg/l Performance Standards :  Performance Standards Phosphorus Tiers PSP 1 3.9 mg/L Case-by-case for 20,000 gpd and larger PSP 2 7.85 mg/l Case-by-case for 2,500 – 20,000 gpd Case-by-case determination based on: Soil tests and Groundwater P concentrations Site has seasonal high water table above 27 inches Stormwater:  Stormwater Voluntary Innovative designs such as rain gardens, natural landscaping, and constructed wetlands are encouraged where appropriate. Develop a program to assist homeowners’ associations in the creation of a stormwater maintenance plan as well as to assist in the establishment of a funding mechanism to meet financial obligations for related stormwater facility maintenance. Institute tax incentives that encourage an increase in open space (green areas) in commercial developments, thus, reducing the percentage of impervious surface and reduce nutrient contributions. Stormwater:  Stormwater Voluntary Encourage Sussex County to create a stormwater utility for the Inland Bays Watershed. This utility would collect fees for the construction (in older developments) and maintenance of stormwater management structures. Create stormwater management facilities for 4500 acres of urban and residential lands developed pre-1990. 67 lb TN reduced and 4.6 lbs TP reduced $76-142/lb TN reduced Stormwater:  Stormwater Regulatory Where practicable, all permanent sediment and stormwater management plans shall be designed and implemented to reduce nutrient contributions by the percentage required by the TMDL to the ground and surface waters to the maximum extent practicable comparison between the post-developed condition with and without stormwater quality management best management practices In instances where other pollutants would be best controlled through other means, the Department may permit management based on the best treatment for the particular pollutant of concern. Concurrence:  Concurrence Voluntary Form a task force to examine laws, regulations and ordinances that are in effect within the Inland Bays Watershed. This group will then identify areas where adjustments are needed in order to have concurrence. Concurrence:  Concurrence Regulatory All isolation, set-backs and separation distances shall be maintained in accordance with existing regulations, ordinances and codes. The use of advanced nutrient reduction technology shall not be used as justification for reductions in isolation, set-back and/or separation distances. All water quality impacting permits shall be consistent with the Surface Water Quality Standards (SWQS). The Department will begin creating a process to ensure that all wastewater and stormwater permits meet these standards. NPS Progress to Date:  NPS Progress to Date 26% 60% The Goal:  The Goal Stormwater Wastewater Achieved Agriculture 107% 100% Future Costs :  Future Costs Price of N Reduction :  Price of N Reduction $1 = Price of P Reduction :  Price of P Reduction $1 = The Goal:  The Goal Stormwater Wastewater Achieved Agriculture 107% 100%
