DDW 2020 Regulatory Priorities

At today’s State Water Resources Control Board (SWRCB) meeting Division of Drinking Water (DDW) staff presented the enclosed Regulatory Priorities for 2020. (DDW Reg Priorities_2020)  The SWRCB adopted the Regulatory Priorities as presented.

Some highlights from the enclosed:

  1. Page 3, item 2b. Revised Lead DLR.   DDW anticipates proposing in 2020 a revised Detection Limit for Purposes of Reporting (DLR) for lead (“….and several other metals”).  The revised DLR for lead “may” be lowered from 5 parts per billion (ppb) to 1 ppb.
  2. Page 4, item 4.  Revised Total Coliform Rule.  DDW plans to publish the draft Revised Total Coliform Rule for public comment during “spring 2020.”
  3. Page 5, item 9.  Revised Perchlorate DLR.  DDW staff completed a survey of laboratory perchlorate capabilities.  The results “demonstrated an ability to lower the DLR without sacrificing capacity, but not to a level equal to or less than the PHG at this time….The proposed revision to the DLR is slated for Board consideration in June 2020.”  Background:  The MCL for perchlorate is 6 ppb, the PHG is 1 ppb, and the DLR is 4 ppb.

With regard to dates for the three public workshops on DDW’s White Paper on “Economic Feasibility Analysis in Consideration of a Hexavalent Chromium MCL,” ACWA staff indicate the following information was reported at the Board’s meeting:

  • April 15 – Diamond Bar
  • April 17 – Rancho Cordova (Central Valley Water Board’s headquarters)
  • April 20 – Fresno

The workshop dates and more detailed information on time and location have not yet been posted by DDW.
