(2)Sealing by pressure injection from bottom to top with cement bentonite or other appropriate material to within five feet of the ground surface. The upper five feet may be backfilled with native material, and the entire site must be restored to a safe condition. Where the surrounding geologic deposits are highly permeable, alternative methods of sealing may be required by the Department to prevent migration of grout into the surrounding formation.
(3)Documentation of the abandonment through a written description of the procedures employed, drilling methods and depths, borehole depth and volume and type of sealant employed is required.
6.Solid Waste Characterization Program
A.Applicability. All special wastes proposed for storage, processing, beneficial use, agronomic utilization, or disposal in Maine must be characterized in accordance with a Department-approved plan. Any other solid waste may also be required to be characterized in accordance with a Department-approved plan. Facilities licensed solely for the transfer, storage, and/or disposal of municipal solid waste (MSW), wood waste and/or construction or demolition debris (CDD) are exempt from the characterization requirements of this section.
Solid waste facilities licensed to accept solid wastes characterized by the generator are not required to further characterize the waste at the facility, provided the solid wastes are clearly manifested from the point of generation to the accepting facility.
B.General Program Requirements. The owner or operator of a new solid waste facility or activity required to characterize waste under these rules, or by a license or an enforcement agreement, must develop a solid waste characterization program and submit it to the Department for review and receive approval prior to handling of the wastes. This program must be designed to determine the chemical and physical characteristics of the wastes and to monitor these characteristics on an on-going basis. The owner or operator of an existing solid waste facility or activity which has previously characterized its wastes is required to meet only the ongoing characterization requirements of this section, unless an alternative program is approved by the Department or the owner or operator proposes to handle a new waste stream which requires initial and on-going characterization under this section. The program must include detailed information addressing the following:
(1)General requirements. The applicant must comply with the following requirements in developing and implementing a solid waste characterization program:
(a)For the initial characterization of a waste from a specific source, the owner or operator shall prepare and submit to the Department a detailed description of all known or potential physical and chemical characteristics of the solid waste to be accepted for handling. This must include information regarding the materials and specific process from which the waste is generated, and Material Safety Data Sheets for those chemicals that may be a major component of the waste. Information may be obtained from the facility generating the waste, analytical results from a similar facility, and/or from the chemical literature.
(b)The applicant shall also include a complete list of references for all sources of information used in this assessment.
(c)All wastes proposed to be handled under the provisions of these rules must be fully characterized unless exempted from characterization. Any statistical analysis performed must be done in accordance with the requirements of US EPA SW-846, Test Methods for Evaluating Solid Waste, Fourth Edition, Volume II, Chapter 9. Waste must not be accepted at a solid waste facility or for
