EXECUTIVE SUMMARY,PURPOSE OF SUBMITTAL, The San Diego Metropolitan Sewerage System Metro System provides wastewater service for. the City of San Diego and 12 participating agencies The E W Blom Point Loma Wastewater. Treatment Plant Point Loma WWTP serves as the terminal Metro System treatment facility. The discharge of treated wastewater from the Point Loma WWTP to the Pacific Ocean via the. Point Loma Ocean Outfall PLOO is currently regulated by a joint permit issued by the. California Regional Water Quality Control Board San Diego Region Regional Board and the. U S Environmental Protection Agency EPA Regional Board Order No R9 2009 0001 EPA. NPDES CA0107409 establishes modified secondary treatment requirements for the PLOO. discharge in accordance with Sections 301 h and 301 j 5 of the Clean Water Act. Order No R9 2009 0001 was originally adopted by the Regional Board on June 10 2009 EPA. issued final approval of the joint NPDES permit on June 16 2010 and the permit became. effective on August 1 2010 Order No R9 2009 0001 expires on July 31 2015 and the City is. required to file a Report of,Waste Discharge requesting. renewal of the NPDES,permit 180 days in advance,of this expiration date.

January 2015 Executive Summary,BASIS OF SUBMITTAL, Renewal of Current NPDES Requirements The City of San Diego s comprehensive.
effluent and receiving water monitoring program 1 has documented that the combination of. enhanced source control flow diversion to recycled water use chemically enhanced primary. treatment at the Point Loma WWTP,and a deep and efficient ocean outfall. ensures that the PLOO discharge,complies with all NPDES permit. limits and all applicable state and,federal water quality based standards 2. In addition to implementing water,quality based standards to protect. receiving waters the Clean Water Act,establishes a technology based.
standard that requires secondary The City s comprehensive effluent and receiving water monitoring. treatment for all municipal wastewater program demonstrates consistent compliance of the Point Loma. discharge with all discharge permit limits and requirements. discharges to inland estuarine or, marine receiving waters Sections 301 h and 301 j 5 of the Clean Water Act however. acknowledge that technology based secondary treatment requirements may not be appropriate. for all discharges and all receiving waters and allow EPA to issue modified secondary treatment. requirements for dischargers that 1 comply with applicable receiving water standards 2 do. not unreasonably impact beneficial uses and 3 result in the maintenance of healthy balanced. indigenous populations of fish and benthic bottom dwelling species outside the designated. zone of initial dilution After review of the City s three prior NPDES applications 1995 2002. and 2007 for modified secondary treatment requirements EPA determined in each instance that. the PLOO discharge qualified for modified TSS and BOD requirements under Sections 301 h. and 301 j 5 of the Clean Water Act, Requested TSS and BOD Limits This permit application requests renewal and. continuation of the following TSS and BOD percent removal requirements established in Order. No R9 2009 0001 pursuant to requirements of Clean Water Act Sections 301 h and 301 j 5. monthly average system wide removal of TSS of 80 percent and. annual average system wide removal of BOD of 58 percent. Results from the City s comprehensive effluent monitoring program for the current NPDES permit period are summarized in City of San Diego. 2011a 2014a Results from the City s comprehensive ocean monitoring program are summarized in City of San Diego 2011b 2014b. A water quality based standard is a standard that is implemented to protect receiving water quality and ensure protection of beneficial uses. including human health and aquatic habitat, A technology based standard mandates implementation of a certain treatment technology regardless of the conditions or quality of a given. receiving water,City of San Diego NPDES Permit and.

To the contrary this application is,based on a new direction in water. and wastewater facilities planning,for the City of San Diego that. proposes to systematically reduce,future PLOO discharge flows and. solids mass emissions through,implementation the Pure Water. San Diego program Pure Water,San Diego is a long term approxi.
mately 20 year program that,would provide a safe reliable and. cost effective drinking water, The Pure Water San Diego program has a goal of producing up to 83 supply for San Diego through the. million gallons per day of purified water by December 31 2035 which application of advanced treatment. would significantly reduce the City s dependence on imported water. technology to purify recycled, water The Pure Water San Diego program is a joint water and wastewater facilities plan that. envisions a significant investment in potable water reuse and ancillary facilities that will. eventually produce up to 83 million gallons per day mgd of potable supply an amount that. equates to approximately one third of the total City of San Diego potable water demand. The Pure Water San Diego program is the result of collaboration between the City of San Diego. Metro Wastewater Joint Powers Authority JPA and a diverse array of regional stakeholders. The City Metro Wastewater JPA and regional stakeholders have agreed to cooperate to. implement a comprehensive potable reuse program using state of the art advanced. treatment technology to achieve an ultimate goal of 83 mgd of potable reuse by. December 31 2035, sufficiently reduce influent flows and solids loads to the Point Loma WWTP so that. ultimate PLOO TSS mass emissions are reduced to levels that would have occurred if the. 240 mgd Point Loma WWTP were to achieve secondary treatment TSS concentration. support the City s application for renewed 301 h modified TSS and BOD limits for the. Point Loma WWTP and,City of San Diego NPDES Permit and.
Public Utilities Department EX 3 301 h Application. January 2015 Executive Summary, support the City s pursuit of administrative or legislative efforts to codify that as a result. of implementing the comprehensive Pure Water San Diego program the PLOO. discharge is recognized as equivalent to secondary treatment for purposes of compliance. with the CWA secondary treatment equivalency, To demonstrate the City s commitment to regulators and stakeholders for moving forward with. Pure Water San Diego plans this NPDES application proposes that the following enforceable. provisions be incorporated into the renewed Point Loma WWTP 301 h permit. Reduction in PLOO Mass Emissions The current Order No R9 2009 0001 establishes. requirements that limit PLOO TSS mass emissions to 13 598 metric tons per year in the final. year of the five year permit As part of the proposed renewed 301 h NPDES permit it is. proposed that allowable PLOO TSS mass emissions be reduced to 12 000 metric tons per. year for years 1 through 4 of the renewed permit and to 11 999 metric tons per year during. year 5 of the renewed NPDES permit, Enforceable Time Schedule Milestones To further demonstrate the City s commitment to. regulators and regional stakeholders to implement the Pure Water San Diego program and. offload Point Loma WWTP inflows and solids loads the City proposes that the renewed. 301 h NPDES permit incorporate an enforceable time schedule governing implementation. of Pure Water San Diego environmental review and facilities design tasks Table EX 1 page. EX 5 presents the enforceable time schedule tasks proposed for inclusion within the. renewed five year NPDES permit, Long Term Pure Water San Diego Goal The long term Pure Water San Diego goal. of the City and its regional partners is to achieve a targeted potable reuse production capacity of. 83 mgd by December 31 2035,This 83 mgd potable reuse.
