Section 02B .0406 - TECHNOLOGY BASED EFFLUENT LIMITATIONS

(a) Municipal (POTW) Wastewaters and Other Similar Discharges

(1) Applicability. This Paragraph is applicable to all municipal wastewater treatment discharges and all discharges consisting primarily of domestic sewage. In addition to the limits contained in this Paragraph, limits applicable to industrial categories contained in Paragraph (b) of this Rule shall be applicable to any municipality if influent waste discharges from industries in any single category account for 10 or more percent of its average daily wastewater flow or the industrial discharges significantly impact the municipal system or its effluent discharge.

(2) Effluent limitations, except for waste stabilization ponds subject to Subparagraph (3) of this Paragraph, shall include the following:

SECONDARY		"BPWTT"
Effluent Characteristic	Monthly Avg.	Weekly Avg. Max.	Avg.	Max.
BOD(5)	30 mg/l	45 mg/l	Reserved
TSS	30 mg/l	45 mg/l	Reserved
Fecal Coliform	(Effluent limitations for coliform bacteria and pH shall be imposed only if necessary to maintain compliance with applicable water quality standards.)		Reserved
pH			Reserved

(3) Effluent limitations for waste stabilization ponds shall include the following, provided that:

(A) Waste stabilization ponds are the sole process used for secondary treatment;

(B) The maximum facility design capacity is two million gallons per day or less; and

(C) Operation and maintenance data indicate that the requirements for TSS of Subparagraph (2) of this Paragraph cannot be achieved.

SECONDARY		"BPWTT"
Effluent Characteristic	Monthly Avg.	Weekly Avg. Max.	Avg.	Max.
BOD(5)	30 mg/L	45 mg/L	Reserved
TSS	90 mg/L	135 mg/L	Reserved
Fecal Coliform	(Effluent limitations for coliform bacteria and pH shall be imposed only if necessary to maintain compliance with applicable water quality standards.)		Reserved
pH			Reserved

(b) Industrial Waste Discharges.

(1) Applicability. This Paragraph is applicable to industrial wastewater treatment discharges.

(2) Effluent limits for industrial waste discharges are set forth in regulations promulgated by the Environmental Protection Agency, including those in 40 CFR Chapter I, Subpart N - Effluent Guidelines and Standards, which are hereby incorporated by reference, including any subsequent amendments and editions.

(3) For industrial categories or parts of categories for which effluent limits and guidelines have not been published and adopted, effluent limitations for existing industrial waste discharges, or new industrial waste discharges shall be calculated by the staff using the projected limits of the Environmental Protection Agency, the Environmental Protection Agency development document, and other available information in order to achieve the purposes of Article 21.

(4) On a case-by-case basis, if the staff determines, based on its professional judgment and applicable State and Federal guidelines, Rules, and laws, that effluent limits established by Subparagraph (b)(2) of this Paragraph are not adequate to control settleable solids, the staff shall establish effluent limits for settleable solids. Such effluent limitations for settleable solids shall be applicable only when the projected average solids concentration exceeds 5.0 ml/l and the limitations established shall lie within the range of 0.1 ml/l to 5.0 ml/l.
