Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Dilution here is >30:1. Limits for pH, BOD5, and TSS are BPT limits for plastic, nylon, and
tape products (SUBPART 140 CFR 414.41). The OCPSF guidelines were given as defined in 40
CFS 414.91. These limits are based on the highest monthly average OCPSF-contributing flow in
the past 12 months. A new fluoride limit was calculated using 17 MGD flow (cooling water and
process water) and the latest S7Q10 statistic, assuming no background fluoride levels. This
resulted in the new limit given as a concentration not a mass. The toxicity test will remain a
pass/fail chronic analysis using ceriodaphnia but will be given at an IWC of 3.2% because per;

MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS
Adequacy of Existing Treatment
Has the facility de nstrated the ability to meet the proposed new limits with existing treatment
facilities? Yes No
If no, which parameters cannot be met?
Would a "phasing in" of the new limits be appropriate? Yes No
If yes, please provide a schedule (and basis for that schedule) with the regional
office recommendations:
If no, why not?
Special Instructions or Conditions
Wasteload sent to EPA? (Major) (Y or N)
