Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 304 - EFFLUENT STANDARDS › Subpart A - GENERAL EFFLUENT STANDARDS › Section 304.102 - Dilution

Current through Register Vol. 48, No. 28, July 12, 2024
a) Diluting the
				effluent from a treatment works or any wastewater source is not acceptable as a
				method of treatment of wastes to meet the standards in this Part. It is the
				obligation of any person discharging contaminants of any kind into the waters
				of the State to provide the best degree of treatment of wastewater consistent
				with technological feasibility, economic reasonableness, and sound engineering
				judgment. In determining what kind of treatment is the "best degree of
				treatment" within the meaning of this subsection, a person must consider the
				following:
1) What degree of waste reduction
				can be achieved by process change, improved housekeeping, and recovery of
				individual waste components for reuse; and
2) Whether individual process wastewater
				streams should be segregated or combined.
Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 304 - EFFLUENT STANDARDS › Subpart A - GENERAL EFFLUENT STANDARDS › Section 304.103 - Background Concentrations

Current through Register Vol. 48, No. 28, July 12, 2024
Because the effluent standards in this Part are based on
				  concentrations achievable with conventional treatment technology that is
				  largely unaffected by ordinary levels of contaminants in intake water, they are
				  absolute standards that must be met without subtracting background
				  concentrations. However, these rules do not intend to require users to clean up
				  contamination caused essentially by upstream sources or to require treatment
				  when only traces of contaminants are added to the background. Compliance with
				  the numerical effluent standards is not required when effluent concentrations
				  greater than the standards result entirely from influent contamination,
				  evaporation, or the incidental addition of traces of materials not used or
				  produced in the activity that is the waste source.

a) Except as
				otherwise specifically provided, proof of violation of the numerical standards
				of this Part must be based on one or more of the following averaging rules:
1) A monthly average must not exceed the
				prescribed numerical standard.
2) A
				daily composite must not exceed two times the prescribed numerical

3) A grab sample must not

Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 304 - EFFLUENT STANDARDS › Subpart A - GENERAL EFFLUENT STANDARDS › Section 304.105 - Violation of Water Quality Standards

Current through Register Vol. 48, No. 28, July 12, 2024
In addition to the other requirements of this Part, effluent
				  must not, alone or in combination with other sources, cause a violation of any
				  applicable water quality standard. When the Agency finds that a discharge that
				  would comply with effluent standards in this Part would cause or is causing a
				  violation of water quality standards, the Agency must take appropriate action
				  under Section 31 or Section 39 of the Act to require the discharge to meet
				  whatever effluent limits are necessary to ensure compliance with the water
				  quality standards. When such a violation is caused by the cumulative effect of
				  more than one source, several sources may be joined in an enforcement or
				  variance proceeding, and measures for necessary effluent reductions will be
				  determined based on technical feasibility, economic reasonableness, and
				  fairness to all dischargers.

a) Effluents
				discharged to all general use waters must not exceed 400 fecal coliforms per

				standard only in compliance with the requirements of 35 Ill. Adm. Code
				302.209 and
				302.306.
1) The discharger must demonstrate and
				document the following:
A) The character of
				the receiving waters under 35 Ill. Adm. Code
				302.202, 302.209, and
				302.306.
B) The discharge will not
				cause downstream waters to exceed the applicable fecal coliform water quality
				standards under 35 Ill. Adm. Code

Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 304 - EFFLUENT STANDARDS › Subpart A - GENERAL EFFLUENT STANDARDS › Section 304.122 - Total Ammonia Nitrogen

Current through Register Vol. 48, No. 28, July 12, 2024
a) Effluent
				from any source that discharges into the Illinois River, the Des Plaines River
				downstream of its confluence with the Chicago River System, or the Calumet
				River System, and whose untreated waste load is 50,000 or more population
				equivalents must not contain more than
				2.5 mg/L of total ammonia
				nitrogen as N during the months of April through October, or 4 mg/L at other
				times.
b) Sources discharging to
				any of the above waters and whose untreated waste load cannot be computed on a
				population equivalent basis comparable to that used for municipal waste
				treatment plants and whose total ammonia nitrogen as N discharge exceeds
				45.4 kg/day (100 pounds per day)
				must not discharge an effluent of more than
				3.0 mg/L of total ammonia
				nitrogen as N.
c) In addition to
				the effluent standards in subsections (a) and (b), all sources are subject to
				Section 304.105
Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 304 - EFFLUENT STANDARDS › Subpart A - GENERAL EFFLUENT STANDARDS › Section 304.123 - Phosphorus

Current through Register Vol. 48, No. 28, July 12, 2024
a) Effluents
				discharged within the Lake Michigan Basin must not contain more than
				1.0 mg/L of phosphorus as
				P.
b) Effluents from any source
				that discharges to a lake or reservoir with a surface area of
				8.1 hectares (20 acres) or more,
				or to any tributary of such a lake or reservoir whose untreated waste load is
				2500 or more population equivalents, and which does not utilize a third-stage
				lagoon treatment system as specified in Section
				304.120(a) and
				(c), must not exceed
				1.0 mg/L of phosphorus as P;
				however, this subsection does not apply where the lake or reservoir, including
				any side channel reservoir or other portion of it, on an annual basis exhibits
				a mean hydraulic retention time of
				0.05 years (18 days) or
				less.
c) Under Section
				28.1 of the Environmental
				Protection Act (Act) [415 ILCS 5/28.1 ], the owner or
				operator of any source subject to subsection (b) may apply for an adjusted
				standard. In addition to the proofs specified in Section
				28.1(c) of the
				Act [415
				ILCS 5/28.1(c) ], the application
				must, at a minimum, contain adequate proof that the effluent resulting from
				granting the adjusted standard will not contribute to cultural eutrophication,
				unnatural plant or algal growth or dissolved oxygen deficiencies in the
				receiving lake or reservoir. For purposes of this subsection, effluent must be
				deemed to contribute to such conditions if phosphorus is the limiting nutrient
				for biological growth in the lake or reservoir, taking into account the lake or
				reservoir limnology, morphological, physical and chemical characteristics, and
				sediment transport. However, if the effluent discharge enters a tributary at
				least 40.25 kilometers (25 miles)
				upstream of the point at which the tributary enters the lake or reservoir at
				normal pool level, effluent will not be deemed to contribute to such conditions
				if the receiving lake or reservoir is eutrophic and phosphorus from internal
				regeneration is not a limiting nutrient.
d) For this Section, the term "lake or
				reservoir" does not include low-level pools constructed in free-flowing streams
				or any body of water that is an integral part of an operation that includes the
				application of sludge on land.
e)
				Compliance with the limitations of subsection (b) must be achieved by the
				following dates:
1) Sources with the present
				capability to comply must do so on the effective date of this
				Section;
2) All other sources must
				comply as required their NPDES permits.
