On July 19, 2013, DDOE released the 2013 Rule on Stormwater Management and Soil Erosion and Sediment Control (2013 SW Rule), which amended Chapter 5 (water Quality) of Title 21 (Water and Sanitation) of the District of Columbia Municipal Regulations (DCMR). DDOE also released the 2013 Stormwater Management Guidebook (2013 SWMG), which provides technical guidance on how to comply with the rule.
Transition to 2013 SW Rule and 2013 SWMG
Section 552 of the 2013 SW Rule describes DDOE’s plan for transitioning to the new stormwater management performance requirements. The official language is in the DCMR, but for the convenience of the public DDOE has provided a summary of the transition plan. Other provisions of the 2013 SW Rule (including those for erosion and sediment control, Stormwater Retention Credit trading, and service fees) take effect upon final publication of the rule.
Projects that are regulated under Transition Period 1 of the transition plan may continue to use the existing design standards and specifications in the 2003 SWMG that is attached below.
