The Standard Operating Procedure (SOP) describes the trash receiving waters monitoring protocol that was implemented during the pilot-testing phase (October 2017 – February 2020) of the BASMAA Trash Monitoring Program Plan.  The protocol includes a qualitative and quantitative method for measuring trash accumulation in a geographically defined assessment area located in creeks, channels, rivers, lagoons and shorelines within the jurisdictional areas of BASMAA member agencies.  The protocols and methods in this SOP are based on a review of historical and current receiving water monitoring efforts for trash.

This Reasonable Assurance Analysis (RAA) Guidance Document describes the background, requirements, and recommended approach for conducting RAAs for programs and permittees subject to the Municipal Regional Stormwater Permit (MRP) (Order No. R2-2015-0049). For the purposes of this Guidance Document, an RAA is a demonstration that the control measures proposed in the MRP Permittees’ Green Infrastructure Plans and Polychlorinated Biphenyls (PCBs) and Mercury Control Measure Implementation Plans (see Section 2.1.3) as required by MRP Provisions C.3, C.11, and C.12, will meet the PCBs and mercury Total Maximum Daily Load (TMDL) wasteload allocations for urban stormwater runoff.
