Code of Maine Rules › 06 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 096 - DEPARTMENT OF ENVIRONMENTAL PROTECTION - GENERAL › Chapter 555 - STANDARDS FOR THE ADDITION OF TRANSPORTED WASTES TO WASTEWATER TREATMENT FACILITIES › Section 096-555-7 - Criteria for approval

Current through 2024-29, July 17, 2024
A.
Strength
				of wastes
. As arebuttable presumption for the purposes of this rule, the
				strength of transported wastes is assumed to be: BOD, 7,500 mg/L and TSS,
				15,000 mg/L. To rebut this presumption, wastewater treatment facilities may
				submit to the Department information demonstrating the strength of transported
				wastes it intends to receive. This may be for the aggregate of all wastes
				received or for specific sources or classes of sources where those sources are
				significantly different than the aggregate. Additionally, the facility may
				provide information on the strength and characteristics of transported wastes
				added to the wastewater treatment process following side stream treatment where
				the side stream treatment significantly alters the characteristics of the
				wastes as received from the transporter.
B.
Quantity of wastes.
Except as
				provided in section 8(B), the amount of transported wastes may not, in
				combination with other current annual average influent loadings, cause a
				wastewater treatment facility's design capacity for flow, BOD, TSS or other
				relevant pollutants to be exceeded. The volume of transported wastes received
				per day at a wastewater treatment facility may not exceed the following volumes
				in comparison to the facility's design capacity.
(1) Where the facility does not utilize side
				stream treatment or storage, the daily maximum volume received may not exceed
				0.5% of the design capacity.
(2)
				Where the facility does utilize side stream treatment or storage for at least
				half of the transported waste, the daily maximum volume received may not exceed
				1.0% of the design capacity.
(3) A
				facility may propose to receive a daily maximum volume of more than 1.0% of the
				design capacity. The daily maximum volume must be determined by the Department
				based on a case-by-case review. Such a review must consider the extent to which
				the facility utilizes side stream treatment or storage that substantially
				reduces the strength or quantity of wastes added to the influent wastewater
				flow, and the potential impacts of the transported wastes on the wastewater
				treatment processes, effluent quality, receiving water conditions, the safe and
				proper operation of the facility, sludge quality, and the surrounding
				community. In addition to the information described in section 5, the
				application should include supplemental details regarding the following.
(a) A description of management practices and
				other controls that will be followed to prevent adverse impacts from odors on
				the surrounding community, including attested copies of any relevant
				ordinances;
(b) A description of
				management practices and other controls that will be followed to prevent
				adverse impacts from transporter traffic on the surrounding community,
				including attested copies of any relevant ordinances;
(c) A description of the treatment method(s)
				to be used and the quantity of wastes consigned to each;
(d) The pollutant loadings in pounds per day
				for BOD, TSS and other identified pollutants of concern that each side stream
				treatment method places on subsequent wastewater treatment process
				units;
(e) A narrative description
				of the operational practices and procedures that will be used to minimize the
				impact of transported wastes on wastewater treatment processes, the quality of
				the effluent discharged, and sludge disposal practices. This may include
				operational plans for side stream treatment or storage and how they are managed
				in concert with overall facility operations; and
(f) An analysis of additional facility
				staffing or operational needs created by the transported wastes received and,
				where necessary, a description of how those needs will be met.
