A previous analysis was performed (in August,, 1988) for this discharge at 0.181 MGD and subsequently a permit was issued for that flow. In response to a request from the Construc- tion Grants Unit, a speculative analysis was performed for 0.55 MGD in July, 1989. The results were used in the planning process for the facility. Limits: Summer Winter Wasteflow (MGD 0.55 0.55 BODS (mg/1) 20 30 NH3N (mg/1) 12 -- DO (mg/1) 5 4 TSS (mg/1) 30 30 Fecal Coliform (#/100ml) 1000 1000 The Environmental Protection Agency's (EPA) review of this WLA determined that these limits would not protect for ammonia toxicity instream. A letter sent Sept. 8, 1989, form Sally Turner indicated that the ammonia limits should be 2 mg/l for summer and 4 mg/l for winter. Construction Grants was notified in Sep- tember; 1989 of EPA's request for stricter ammonia limits. Trevor Clements talked with Dan Blaisedale and he confirmed that the limits change would not affect the design. However, Construction Grants is worried that Badin will not consistently achieve nitrification because of a bad I&I problem and they would prefer the original limits (above). Trevor warned Dan B. that we would add a chronic bioassay requirement if the limits were not revised. For this permit modification, the facility will be given a choice ofa chronic toxicity testing requirement (at 77% effluent concentration) or an ammonia limit to protect against toxicity. The Speculative review performed•by Technical Support in July 1989 did not con- sider ammonia toxicity protection since we did not implement the procedure until February 1990. During the analysis for this,WLA.request, it was determined that the ammonia limit needed to reflect concentrations of 1.2 mg/l NH3N for summer"and 2.7 mg/l NH3N for winter in order to'protect against toxicity in the stream. The model was re -run with limits of 20 mg/l BODS (30 mg/l CBOD) and 1.2 mg/l NH3N (5.4 mg/1 NBOD). The End Results: DO = 7.55 mg/l CBOD = 11.55.mg/l NBOD = 0.90 mg/l a These concentrations are predicted to enter an arm of Lake Tillery (Pee Dee River). Since this analysis is a 201 project, T.S. will not -at this time evaluate the model any further, but beam request instream monitoring for nutrients.
