Chesapeake Bay TMDL Action Plan - Public Comment
Chesapeake Bay TMDL Action Plan - Public Comment
This Phase II Chesapeake Bay TMDL Action Plan builds on Fairfax County’s Phase I Chesapeake Bay TMDL Action Plan approved by the Virginia Department of Environmental Quality (DEQ) on August 15, 2017. The plan documents how the County intends to meet the “Chesapeake Bay TMDL Special Condition” in Part I D 1 of its Municipal Separate Storm Sewer System (MS4) permit that became effective January 4, 2024 (2024 MS4 permit).
Virginia adopted a Watershed Implementation Plan (WIP) that establishes the framework for meeting the Chesapeake Bay TMDL. The Virginia WIP states that MS4 permit holders will implement a phased approach to reduction targets over three five-year permit cycles in accordance with the following:
- 5% by the end of the first permit cycle (June 30, 2018);
- 40% by the end of the second permit cycle (2023); and,
- 100% by the end of the third permit cycle (2028).
Because Fairfax County’s 2015 permit was administratively continued for approximately five years, the 2024 MS4 permit establishes an alternate schedule for meeting the required reductions: 40% of the required reductions by June 30, 2026 and 100% of the required reductions by June 30, 2028. This Phase II Chesapeake Bay TMDL Action Plan establishes the County’s 40% reduction target and identifies the BMPs for achieving the target in accordance with the 2024 MS4 permit, DEQ Guidance Memo No. 20-2003, and other guidance received by DEQ.
