The Los Angeles Regional Water Quality Control Board (Regional Board) has recently updated guidance on how to complete Section 1.4 , Water Body Pollutant Combination (WBPC) compliance analysis for the Watershed Management Program (WMP) Progress Report.

The additional budget w ill give LWA sufficient resources for the added complexity and hours that are now needed to complete this analysis in line with the updated Regional Board guidance through the end of the contract on June 30, 2024.
This augment will be added to Task 003, Reporting , as indicated in the table below. On approval , the budget amounts, budget remaining, and % spent for each tas k will be updated and reflected on the following monthly invoice.
