EPA Evaluation of
Maryland's
2012-2013 Milestone Progress and
2014-2015 Milestone Commitments to
Reduce Nitrogen, Phosphorus and Sediment
Overview
Two-year milestones are short-term objectives under the Chesapeake Bay Total Maximum Daily Load (Bay
TMDL) accountability framework used to assess progress toward restoration goals while allowing jurisdictions
to flexibly adapt their Watershed Implementation Plans (WIPs) to meet those goals. When fully implemented,
the seven WIPs will ensure all practices necessary to meet water quality standards in the Chesapeake Bay will be
in place by 2025. By 2017, jurisdictions should have practices in place that would achieve 60 percent of necessary
pollutant reductions compared to 2009.
Pollutant Reduction Progress and Future Targets by Source Sector
According to the data provided by Maryland, die state achieved its 2013 milestone targets for nitrogen, phosphorus
and sediment. Maryland finished the 2012-2013 milestone period more dian 3.5 million pounds ahead of schedule
for nitrogen reductions, nearly 147,000 pounds ahead of schedule for phosphorus reductions, and nearly 90 million
pounds ahead of schedule for sediment.
Maryland's 2014-2015 milestone wastewater snategy and best management practice (BMP) commitments for other
source sectors would reduce nitrogen by more than 5.1 million pounds, phosphorus by nearly 240,000 pounds and
decrease sediment by more than 154 million pounds by die end of 2015, compared to the 2009 baseline.

EPA Evaluation of Maryland's 2012-2013 Milestone Progress and 2014-2015 Milestone Commitments to Reduce Nitrogen, Phosphorus and Sediment
2012-2013 Milestone Progress and 2014-2015 Milestone Review
The EPA review of progress toward meeting 2012-2013 milestones shows Maryland has made enough progress
in the Agriculture and Wastewater sectors to ensure implementation is occurring even though all of the milestone
goals were not achieved. Anticipated reductions for the 2014-2015 milestone period should keep Maryland on
track to meet the 2017 target of having practices in place to achieve 60 percent of reductions necessary to obtain
water quality standards in the Chesapeake Bay.
Strengths
¦	Leading review of historical data for reported best management practices, critical to the TMDL mid-point assessment
¦	Implemented revised agricultural nutrient management regulations and homeowner fertilizer act
¦	Issued final General Permit for Stormwater Discharges Associated with Industrial Activity
¦	Doubled the Bay Restoration Fund fee allowing sufficient grant funds to complete Enhanced Nutrient Removal
upgrades at the 67 major wastewater treatment plants and 5 to 10 minor plants by 2017
¦	Will renew the general discharge permit for animal feeding operations within the 2014-2015 milestone period
¦	Will develop an online BMP reporting tool for non-MS4 local governments
¦	Will develop a tracking system for accounting for new growth by 2015
Shortfalls
¦	Phosphorus Management Tool regulations not completed in specified timeframe; committed to implementing in 2014
¦	Did not submit all draft Phase II MS4 permits and did not issue final determinations for all Phase I MS4 permits to
EPA as specified in 2012-2013 milestone period
¦	Did not complete development of a detailed strategy to upgrade 60 percent of septic systems in the Critical Area
by 2017
Issues to Address
¦	Finalize revised stormwater retrofit guidance under the MS4 permit by September 30, 2014
¦	Issue remaining, expired MS4 permits and construction general permit by agreed upon schedule
¦	Develop and submit a detailed schedule for adopting the Accounting for Growth regulations
Potential Federal Actions and Assistance
EPA will maintain "Ongoing Oversight" of the Alaryland programs for all sectors. EPA may downgrade the Urban/Suburban
Stormwater sector to "Enhanced Oversight" if the following actions are not completed by the agreed-tipon deadlines:
¦	Issue tentative determinations on remaining, expired Phase I MS4 permits by June 30, 2014 and the State Highway
Access permit by December 2014; final determinations for remaining Phase I county permits by December 31, 2014
¦	Issue tentative determinations for Phase II MS4 permits by December 31, 2014 and final determinations by June 15, 2015
¦	Issue final determination for Construction General Permit by December 31, 2014
¦	Sign Letter of Agreement with EPA by June 30, 2014, responding to EPA's assessment of Maryland's stormwater program
EPA is working with U. S. Army Corps of Engineers Baltimore District and other consulting federal agencies, as well
as state and local government representatives, non-governmental organizations and stream restoration practitioners
to improve the efficiency of the permitting process and addressing technical issues and concerns, such as developing
siting criteria and defining monitoring, assessment and performance parameters.
EPA is supporting trading and offset tracking systems and the jurisdictions' development/enhancement of their BMP
verification programs.

commitments, please see Maryland's Full Evaluation Report.
