Dear Mr. Luis A. Flores:
You currently have coverage under NPDES General Permit NCG550000 for Single Family
Residence wastewater discharge. The Division of Water Resources (DWR) understands that the
subject property is having issues with its existing wastewater treatment sandfilter system. Your
authorized consultant, Agri-Waste Technology, Inc., intends to upgrade/install a wastewater
treatment system designed to discharge to Surface Waters of the State in accordance with plans
and specifications signed by the engineer on August 16, 2023. Compliance under General Permit
NCG550000 restricts discharge flow, not to exceed 1,000 gallons per day. This ATC covers
treatment facilities for up to your existing discharge limit of 360 gallons per day(120 gallons per
bedroom).
Please note that you must provide regular treatment-system operation, maintenance and
inspections in accord with manufacturer's recommendations and this ATC; all records, water
analyses, and logs to be kept onsite available for DWR inspection [NCG550000, Section A. (2.)].
Operation and Maintenance. The Permittee is responsible to maintain all components of the
approved treatment system, designed to meet Surface Water-Quality Standards. Compliance
includes following the manufacturer's guidelines, conducting and documenting inspections,
establishing sources for OEM spare parts and supplies, taking samples for analyses, making
necessary repairs, and documenting said maintenance for the duration of the permit. Please
note that the receiving stream is currently classified and governed as WS-II; HQW,NSW, CA
(Water Supply II, High Quality Waters,Nutrient Sensitive Waters, and Critical Area).
If DWR determines that your discharge contributes to future degradation or impairment of this
waterbody, an individual NPDES permit may be mandatory. Upon DWR's request, the
Permittee must provide records and demonstrate regular efforts to maintain the approved
treatment system. The Division recommends that the Permittee solicit manufacture-certified
training, or a qualified contractor or service to regularly inspect and maintain this treatment
system.
