REVISION OF THE PYRETHROID MANAGEMENT PLAN NEEDED FOR THE CITY
OF MERCED AND SUBMITTAL DEADLINE EXTENSION
On 7 February 2022, the City of Merced submitted a Pyrethroid Management Plan (Plan) to comply with the requirements established by the Amendment to the Water Quality Control Plan for the Sacramento River and San Joaquin River Basins for the Control of Pyrethroid Pesticide Discharges (Resolution R5-2017-0057) (Pyrethroid BPA) and the 13 July 2020 Order to submit technical and monitoring reports pursuant to California Water Code Sections 13267 and 13383 issued to the City of Merced (Order).
The Pyrethroid BPA and Order require that the Plan identify a set of management practices that, taken as a whole, may be reasonably expected to effectively reduce pyrethroid levels in discharges. The Pyrethroid BPA and Order also list management practices which must be considered for inclusion in a Plan and require justification regarding the discharger's decision whether to select or not select each practice listed.
A Plan is also required to include a description of progress reporting, description of adaptive management, and consideration of replacement insecticides for pyrethroids.
Central Valley Water Board staff reviewed the City of Merced's Plan and determined that it does not meet the applicable Pyrethroid BPA and Order requirements, specifically Section 3, Item E.1.ii of the Order.
The City of Merced's revised Plan must be submitted to the Stormwater Multiple Application Tracking System (SMARTS) database on or before 30 June 2023 to comply with the Pyrethroid BPA and Order. If the revised Plan is not submitted by 30 June 2023, the Board may pursue enforcement, including potential monetary liability.
Pursuant to the Pyrethroid BPA and through this letter, I am extending the Plan submittal deadline to 30 June 2023 so that the City of Merced may submit a revised Plan for review and approval. This submittal deadline may be further extended as necessary in the future. Dischargers shall begin implementing their Plans within 30 days after receipt of written approval.
