CASQA Releases New Guidance for Trash Implementation Plans

In 2017, the State and Regional Water Boards sent out 13383 Orders specifying the requirements for the development and submittal of Trash Track 2 Implementation Plans. To assist in the development and review of the Plans and to ensure that they are consistent with the 13383 Order requirements, CASQA developed guidance in the form of Track 2 Implementation Plan Checklists for Phase I Permittees in the Regions and for Phase II Permittees statewide (both Traditional and Non-Traditional).


CASQA Provides Guidance for Assessing Industrial General Permit Monitoring Requirements

This document provides guidance to permittees under the Statewide General Permit for Storm Water Discharges Associated with Industrial Activities, Order 2014-0057-DWQ in determining how to assess their monitoring requirements for a facility located in an impaired watershed as identified by the 303(d) list (watershed size based on HUC 10).


CASQA Posts Three New Effectiveness Assessment Subcommittee Products

CASQA conducted a comprehensive review of existing approaches and tools for use in evaluating source contributions (outcome level 4) from key source categories and target audiences, producing a survey, guidance, and a comprehensive database.

CASQA Releases Monitoring & Science Subcommittee Product

CASQA contracted the Southern California Coastal Water Research Project (SCCWRP) to evaluate the spatial variability of bioassessment monitoring to determine the distances that biological indices values could be extrapolated beyond observations (Report: “Spatial stream networks (SSNs): Models to estimate the spatial representativeness of bioassessment samples”).

The report is only available to CASQA members. Logged in CASQA members can view the report in the Member Library under 'Technical Reports'.
