SOURCE CONTROL
b) Inspection of the District's Source Control Program Conducted by
Tetra Tech on Behalf of San Francisco Bay RWQCB and USEPA
to Assess Compliance with Federal Pretreatment Standards
The District's Source Control Program is periodically evaluated by the San Francisco Bay
Regional Water Quality Control Board (RWQCB), U. S. Environmental Protection Agency
(USEPA), or a contractor working for these agencies (e.g. Tetra Tech, PG Environmental)
to assess compliance with the federal pretreatment standards. These standards are
established under the Clean Water Act and are found in 40 Code of Federal Regulations
Part 403. Two levels of evaluation are performed: Pretreatment Compliance Audit (PCA)
and Pretreatment Compliance Inspection (PCI). In general, a PCA is more
comprehensive than a PCI and involves a more thorough review of an agency's sewer
use ordinance (Title 10 of the District's Code - Source Control Ordinance). In general,
approved pretreatment programs are reviewed annually at the PCI level with a PCA being
completed approximately once every five years.
Tetra Tech completed a PCI of the District's pretreatment program on February 25 -26,
2015. One staff from the USEPA participated on the second day. The PCI is structured
with the auditors conducting an interview using a questionnaire provided by USEPA to
assess the District's pretreatment program core elements, file review -of selected
permitted Industrial Users (IUs), field inspections of selected IUs, and an exit interview.
The PCI team reviewed the files for three businesses permitted as Significant IUs:
St. Mary's College, NuWest Textiles, and Systron Donner - Inertial Division. Field
inspections were completed for St. Mary's College, NuWest Textiles and an unpermitted

business operating in Concord, Renaissance Precision Manufacturing, on February 26,
2015. A recent change to the PCI /PCA process is the contact auditors identify businesses
operating in an agency's service area that have not been issued a permit and include one
or more of these businesses in the inspection part of the PCI /PCA to determine if the
business is subject to permitting requirements of the federal pretreatment standards. The
PCI report has historically taken many months to receive but there is an effort by the
RWQCB to be timelier with turning around the reports received by the contract auditors.
Based on this effort, the final PCI report may be available in about two to four months.
