SUMMARY OF CHANGES

SECTION SF 30 - BLOCK 14 CONTINUATION PAGE

The following have been added by full text:

AMDT 0002

What treatment process is presently being deployed for treating the CDF pond water?

Response: As shown in the NPDES permit (on page 339 of 432 of the Specifications package), the process that have been used by the current treatment plant include: 1) addition of alum (aluminum sulfate) to remove high TSS, 2) a multi-media filter (sand and gravel), 3) addition of chlorine (sodium hypochlorite) when Ammonia removal is required (low levels of ammonia are observed in summer and chlorine addition is not required when ammonia levels are below NPDES permit limits in the WWTP influent), 4) granular activated carbon filter, 5) addition of sodium bisulfite to remove residual chlorine during chlorination, 6) bag filters for final polishing prior to discharge to the Canal. It should be noted that dosage of chemicals (e.g., alum and chlorine) can vary depending on influent concentrations. It should also be noted that the current plant had various violations (shown in permit).

According to the drawings provided in the solicitation, there is a WWTP plant adjoining the ponds. Is this plant currently in operation and would that facility be available for operating by a contractor awarded the contract addressed in this RFB?

Response: The current treatment plant contract ends September 2021 and the plant which is a package plant provided by the current treatment plant contractor will be demobilized from the site and is not available for use after September 2021.

How much area is available for setting up a WWTP to address this solicitation?

Sheet CS-102 in the Drawings package shows the area designated for the WWTP. The area is approximately 220’ by 70’, not including areas which will be required for piping from the CDF to the plant and from the plant to the Canal.

Some additional area may be available with coordination with the COR/facility manager/other contractors using the site.
