Dear Mr. Plummer:
SUBJECT: CHANGE IN SERVICE AREA FOR CARLSBAD WATER RECYCLING
FACILITY (CWRF) UNDER MASTER RECLAMATION PERMIT WITH
WASTE DISCHARGE REQUIREMENTS ORDER NO. 2001-352
Thank you for contacting the California Regional Water Quality Control Board (Regional
Board) regarding an agreement between the Carlsbad Municipal Water District
(CMWD) and the Vallecitos Water District (VWD), to provide recycled water to VWD's
landscape irrigation customers located within Carlsbad city limits. This expansion of
service is described in your electronic messages dated October 6, 2008 and October
14, 2008. The proposed .expansion is intended to serve water users in a new housing
development located along the easternmost boundary of Carlsbad, adjacent to the City
of San Marcos.
CWRF currently operates under Order No. 2001-352. From your Master Reclamation
Permit, finding number 10 states:

Hydrologic Subarea (904.31), the Encinas Hydrologic Area (HA 904.40),
the Batiquitos Hydrologic Subarea (HSA 904.51), and the Richland

Mr. William E. Plummer -2- October21, 2008
Change in Service Area for CWRF
Under WDR Order No. 2001 -352
Your proposed service area expansion is within existing Carlsbad city limits. There are
therefore no new hydrologic regions that CWRF will serve at this time.
In order to meet the provisions contained in Division 7 of the California Water
Code and Regulations adopted thereunder, the Carlsbad Municipal Water District
shall comply with all requirements for the discharge and purveyance of recycled
water from the CWRF to HA 904.40, and HSA 904.21, 904.31, 904.51, and 904.52,
as describe in Order No. 2001-352.
These same requirements as described in the Master Reclamation Permit for
Order No. 2001-352 will be in full force and effect for the new service area,
without amendement.
If CMWD decides in the future to expand its recycled water service area beyond these
areas, notify the Regional Board immediately prior to implementing such a plan.
The heading portion of this letter includes a Regional Board code number noted after
"In reply refer to:" In order to assist us in the processing of your correspondence please
include this code number in the heading or subject line portion of all correspondence
and reports to the Regional Board pertaining to this matter.
Sincerely,
Craig L. Carlisle
