Paradise Point Marina -2- • 27 April 2000 Inspection Report defines the discharge point when; the pump station discharges into Bishop Cut located approximately 2000 feet north of the confluence of the Bishop Cut with Disappointment Slough. INSPECTION OF FACILITY: The entire treatment plant is enclosed within a sheet-metal fabricated building. Plant influent is collected within an 800-gallon aerated septic tank sump, which is located adjacent and north of the treatment building. z; f 6 t t, F xi AyY>:'.r1Mki < L E d.x:�N+;IrYm 4 f q Treatment facility is enclosed within sheet-metal A ladder is used to access the top of the Aeration fabricated building. The facility is located adjacent to Chamber where the influent sample is collected. above ground fuel storage area. The inspection of the interior of the facility found it to be adequately maintained. No offensive odors were noted during the facility inspection. The mechanical processes were functional when tested, and no obvious signs of present or past overflow associated with mechanical breakdowns were noted. The facility is fully automated and requires periodic inspection, maintenance and sampling by the operator. No alarm systems other than high/low switches are used with this facility. Mr. Lorimer indicated there has been some minor maintenance of the facility; however, operation of the treatment facility has been incident free. The monitoring and reporting program(MRP)requires continuous flow monitoring on the both influent and effluent. Flow of the effluent is measured by a totalizer, which is triggered every time the effluent pumps are energized. Additionally, the MRP specifies that influent and effluent samples collected for BOD and suspended solids analyses, to be collected as 24-hour composite samples. All samples are presently collected as grab samples. Given the fact the treatment facility operates in batches making the flow monitoring and composite sampling impractical, the existing flow monitoring and sampling meet the intent of the permit. The facility has a design flow of 30,000-gallons per day,but averages only about 3,000 gallons per day. The batch operation processes used by this facility are ideal for accommodating the flow variability generated by PPM. During summer months, flow to the treatment facility is at its greatest. Mr. Lorimer indicates that more frequent sludge removal is required during the summer.
