Delaware’s role in restoring the Chesapeake Bay and our waterways
UPDATE
Where does Bay pollution come from?
Source: EPA
Impact of red areas on Bay water quality at least 10 times higher than blue areas
Delaware is an “effective” polluter of the Chesapeake Bay
• Wastewater• Onsite wastewater (community
systems & septic)• Stormwater• Land use• Agriculture• Restoration• Public lands
Our strategy for meeting the EPA’s required reductions for Nitrogen, Phosphorous and Sediment by 2025 is to focus on these areas:
What’s in Delaware’s plan?
Strategies developed by interagency workgroups
Wastewater • Major treatment plants
include Bridgeville, Laurel, Seaford and Invista
• Operating at or below current permitted capacity
• Phase I WIP recommends modified permits for all significant facilities
• Future growth may trigger need for additional upgrades
Laurel Wastewater TreatmentPlant Upgrade - 2007
Onsite Wastewater• DNREC developing new
inspection requirements and performance standards to meet TMDLs in statewide regulations
• Proposed advanced treatment for all systems within 1,000 feet of Chesapeake tidal waters and wetlands to be implemented as systems fail (2017 milestone)
• Eliminate a minimum of 6,074 systems in this watershed by 2025 as sewer districts expand.
StormwaterStormwater
• Revision of state Sediment and Stormwater regulations – emphasize green technologies, possible in-lieu fee to partially offset new development (2011)– Many best management practices are not included in EPA’s
model – difficult to accurately measure reductions
• Update Industrial Stormwater regulations (2012)• Renewal of DelDOT/New Castle County municipal
stormwater permit (MS4) – only such permit in watershed at this time (2013)
• Stormwater retrofits in older urban areas will be minimal because area is very rural – not cost-effective (EPA had wanted more)
Land Use Land Use • Use state project reviews
and comprehensive planning process to proactively direct growth – especially in Nanticoke corridor (Bridgeville-Seaford-Laurel)
• Reduce fertilizer use on developed lands
• UD completing analysis of watershed to map growth through 2025
• Other Chesapeake states have developed programs for creating and trading nutrient credits
• We must develop plan for offsetting future growth (2012) – Many technical, regulatory and policy challenges will need to be resolved
– Blend offset program for nutrients (quality) and stormwater volume (quantity)
– Can benefit both development and ag communities
• We are improving tool for determining and tracking impacts of land use changes on pollution
Land Use - Offsets
Offset/trading workshop planned for spring 2011
Agriculture Agriculture • Revised Concentrated Animal Feeding Operations
(CAFO) regulations take effect in November– 240 out of 372 CAFOs are in Chesapeake
• State nutrient management regulations also will be updated
• Increase volume of manure relocated out of watershed or sent to alternative use facilities
Perdue pellets
Established aggressive goals for implementation of ag best management practices (tree planting, forest and grass buffers, grazing and tillage practices
– They are most cost-effective way to meet water quality goals
– Improve collection of data on voluntary practices not part of cost-share programs – e.g., Amish
Agriculture
Restoration Restoration • Partners include private
landowners, DelDOT, Delaware Forest Service and Natural Resource Conservation Service
• Restoring headwater forests, channelized streams, and creating stream and wetland buffers will improve water quality
• Gaps in data, funding and outreach exist
Public Lands Public Lands • The state manages
almost 40,000 acres in the watershed
• State and federal stewards will lead by example
• Review opportunities for new Best Management Practices, reforestation
• Funding a challenge
