Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Facility is renewing at existing flow with no change in wastewater characteristics. A choice
between new ammonia limits or a toxicity test at 90% should be given per SOP. Fecal limit should
be 200/100 ml. A letter should be sent regarding the possible toxicity of chlorine. A TP limit of 2
mg/1 should also be given.
