Current through Register 2024 Notice Reg. No. 28, July 12, 2024
On November 14, 2012, the San Francisco Bay Regional Water
					 Quality Control Board (Water Board) adopted Resolution No. R2-2012-0089,
					 amending the Water Quality Control Plan for the San Francisco Bay Region. The
					 State Water Resources Control Board approved the amendment under Resolution No.
					 2013-0007 on March 19, 2013. This amendment establishes total maximum daily
					 loads (TMDLs) for bacteria in San Pedro Creek (Creek) and at Pacifica State
					 Beach (Beach), and incorporates new implementation provisions in the Basin Plan
					 to allow a "reference system and antidegradation approach" for the bacteria
					 water quality objectives. The intent of implementing bacteria water quality
					 objectives using a "reference system and antidegradation approach" is to a)
					 avoid requiring treatment of natural sources of bacteria from undeveloped
					 areas, and b) ensure that bacteriological water quality is at least as good as
					 that of a reference site and that no degradation of existing bacteriological
					 water quality is permitted where existing bacteriological water quality is
					 better than that of a reference site.
The objective of this amendment is to reduce levels of
					 bacteria in San Pedro Creek and at Pacifica State Beach to protect water
					 quality for water contact recreation (REC-1). The TMDL requires reductions in
					 the number of days during the year that levels of bacteria exceed water quality
					 objectives. It allocates discharges of bacteria to municipal stormwater runoff
					 and dry weather flows, stormwater runoff from highways, horse facilities, and
					 sanitary sewer systems, accounting for natural background sources in the
					 watershed.
Required control measures for the existing or new horse
					 facilities will be implemented through the requirements of the Water Board's
					 General Waste Discharge Requirements for Confined Animal Facilities. Required
					 control measures for the sanitary sewer systems will be implemented through the
					 requirements and provisions of the State Water Boards General Waste Discharges
					 Requirements Order for sanitary sewer systems as well as Cease and Desist Order
					 No. R2-2011-0031 issued by the Water Board to Pacifica. Required control
					 measures for municipal stormwater runoff and dry weather flows will be
					 implemented through the Municipal Regional Stormwater NPDES Permit, or a new
					 stormwater NPDES permit. Required control measures for stormwater discharges
					 from Caltrans's storm sewer systems will be implemented thorough Caltrans'
					 existing stormwater NPDES permit requirements.
