(i) An evaluation of data gathered for each surface water monitoring point, if applicable, for the landfill, including a statistical analysis of the data where appropriate.

(ii) For facilities that have leachate collection, an evaluation of the quantity and quality of leachate generated by the landfill during the past year, if applicable, including a comparison of the past year's leachate monitoring results to previous years' results.

H.Closing Requirements. Landfills licensed under the provisions of this section must close in accordance with the requirements of this subsection. Construction/demolition debris landfills less than 6 acres in size that were in existence prior to the effective date of this rule must submit a closure plan to the Department for review and approval prior to beginning closure construction activities. At a minimum, the closure application must meet the following requirements and must address potential contamination issues and any site and slope stability issues that may exist due to site-specific conditions.

(1)Cover Requirements. All landfills licensed under this section must be closed out in accordance with the requirements of this subsection within 180 days of the last receipt of waste and must be graded to a maximum side slope of 3 horizontal to 1 vertical and a minimum top slope of 5%. The final cover must consist of 18 inches of clay or well-graded till containing a minimum of 35% fines overlain by 6 inch soil layer suitable to grow vegetation. The vegetative layer must be seeded with an effective ground cover within one growing season of the completed disposal. Owners/operators must submit a written certification within 45 days of closure completion stating that the facility was closed in accordance with the requirements of this subsection. Final cover for landfills with leachate collection must have a cover system less permeable than the underlying soil and provisions must be made for on-going management of leachate.

(2)Permanent Record. Within 60 days of completion of final closure construction, the licensee shall prepare and record in the Registry of Deeds information and deed restrictions to provide notice to prospective purchasers and a public record of the location of the landfill. The licensee shall provide a copy of the recorded information and deed restriction to the Department.

(a) The information must include:

(i) The type of facility located on the parcel and the dates of its operation and closure.

(ii) A description of the location, composition, extent and depth of the waste deposited.

(iii) The location and identification number of monitoring wells on the property, if any.

(b) A deed restriction must be included. It must state and effectively provide that post-closure use of the property may not disturb the integrity of the final cover, liner system or other components of the containment system, or the functioning of the monitoring systems, without prior written approval of the Department.

I.Post-Closure Requirements. Landfills licensed under this section are subject to the following requirements for post-closure care for a period of 10 years following closure unless extended by the Department due to identified threats to public health, safety, or the environment.

(1)Surface Water Monitoring. If applicable, surface waters must be monitored semi-annually after closure until the Department approves a decrease or cessation in monitoring frequency or parameters or both.

(2)Cover Maintenance. The final cover must be maintained to protect its integrity and prevent ponding of water or erosion of cover materials. Vegetative cover must be mowed annually to prevent the growth of deep rooted, woody plant species. Animal burrows into the cover must be eliminated and the cover repaired as needed.

(3)Drainage. The closed landfill must be kept well drained.

(4)Restricted Access. Provisions must be made to prevent the disposal of additional solid waste on the site and to protect the integrity of the final cover system.

(5)Leachate Monitoring and Maintenance. For facilities with leachate management systems, leachate and the leachate management system must be monitored after closure of the landfill. Leachate management systems must be monitored every four months for quality and flow rates until the Department approves a decrease or cessation in monitoring frequency or parameters or both. Provisions must be made for continued leachate removal and treatment until the Department approves a cessation in removal and treatment.

(6)Inspections. The landfill must be inspected semi-annually after closure in accordance with an approved plan until the Department approves a decrease in frequency or cessation of inspections. Deficiencies noted during inspections must be corrected as soon as weather conditions allow.

(7)Reporting Requirements. The licensee shall submit the results of the monitoring and inspection requirements of this section to the Department. For the first two years of post-closure, the results must be submitted after each inspection. After the first two years, the results must be submitted annually until the Department approves a decrease in reporting frequency. Submittals must include the monitoring results. Deficiencies noted during inspections must be summarized along with corrective measures taken or proposed.

(8)Landfill Reclamation. An owner shall obtain a license pursuant to 06-096 CMR ch. 400 in order to conduct landfill reclamation activities at a closed landfill.
