(a) Sanitary Landfill (Type I operation): To comply with minimum standards each Type I operation must meet or exceed the following requirements: - (i) Each day's deposits of solid waste shall be compacted to the smallest practical volume and a six-inch layer of acceptable cover material shall be placed and compacted over the solid waste at the end of each working day. A minimum of two feet of acceptable cover material shall be placed over any completed segment or cell of the site in such a manner that effective surface drainage will be obtained.
- (ii) The working face of the site shall be confined to the smallest practical area in order to control the exposed waste without interfering with operational procedures.
- (iii) Adequate fencing shall be provided in order to prevent the access to the site by livestock and large wild animals.
- (iv) Adequate fencing shall be provided to catch windblown material. All windblown material shall be collected by attending personnel and returned to the working face once per week or as necessary to prevent the site from becoming unsightly.
- (v) Adequate provisions shall be made for operating during adverse weather conditions. This may be accomplished by providing an emergency disposal area which can be utilized during bad weather.
- (vi) Surface water shall be prevented from entering onto, into or out of the deposited solid waste.
- (vii) Solid waste shall not be deposited nearer than 500 feet to a drinking water supply well, stream, reservoir, lake, water treatment plant, or raw water intake which furnishes water to a public water system or for human consumption unless engineering data supplied to the Department shows there is no danger of the contamination of these waters.
- (viii) Reasonable precautions shall be taken to prevent leachate from the solid waste from entering the surface or ground water.
- (ix) The Department, at its discretion, may require monitoring wells, provided by the responsible person, in order to observe any changes in the quality of the ground water.
- (x) No burning of solid waste shall be conducted at any site without the written permission of the Department.
- (xi) Adequate equipment shall be provided for excavating, compacting, and covering.
- (xii) Adequate personnel or signs shall be provided at each site to give directions for the unloading of refuse.
- (xiii) All weather access roads shall be provided at each site.
- (xiv) A fire lane (minimum 10 feet wide around the perimeter of the site) and other fire protection shall be provided at each site. This may be accomplished by a water supply, stockpiled earth, nearby fire department, or other acceptable means.
- (xv) Hazardous materials may be disposed of in a municipal solid waste disposal site only if the Department gives special written permission. This permission can be obtained by submitting in writing the type, physical composition and chemical composition of the waste and the special procedures and precautions to be taken in handling and disposing of the hazardous waste. There will be some types of hazardous waste that will not be allowed to be deposited in a municipal site. Special directions for the disposal of these wastes will be given by the Department.
- (xvi) Salvaging and reclamation, if permitted, will be conducted in such a manner as not to interfere with normal operating procedures.
- (xvii) The site shall be operated in such a manner so as to control insects and rodents. Additional control in the form of pesticides may be required.
- (xviii) Scavenging and animal feeding or grazing by domestic livestock shall not be permitted on the site.
- (xix) Adequate provisions shall be made for the handling and disposal of bulky waste. If this type material cannot be combined with normal municipal refuse, a separate unloading or alternate area shall be provided on-site for the handling and ultimate disposal of large or bulky items. These items (junk cars, tires, tree stumps, appliances, etc.) shall not be stored on-site in such a manner or for periods of time that they will create a public nuisance, fire hazard, public health hazard, or detriment to the environment.
- (xx) Special provisions shall be made for the acceptable disposal of dead animals. Dead animals should be covered with six inches of cover material upon disposition. Small animals can be worked into the operating face of the landfill, but provisions should be made for the disposal of large dead animals.
- (xxi) When a site is completed or disposal operations are temporarily suspended, all refuse in the area shall be covered with at least two feet of topsoil and reseeded if sufficient vegetation is not available to stabilize the surface. The person who received the written approval of the Department will be responsible for the repair of any eroded, cracked and uneven areas for a period of three (3) years after completion of the site.
- (xxii) The person who was given permission to operate will be responsible for controlling any gases or leachate from a site for a period of five (5) years after completion of the site.
- (xxiii) Street sweepings may be stored temporarily or utilized in areas where they do not create public nuisances, aesthetic degradation, or public health hazards.
(b) Type II Operation (modified landfill): To comply with minimum standards, each Type II operation must meet or exceed all standards required of a Type I operation except a six-inch well-compacted cover material will be required only once per week.
(c) Type III Operation (modified landfill): To comply with minimum standards, each Type III operation must meet all the requirements of a Type I and II operation except a six-inch well-compacted cover material will be required only once per month.
(d) Demolition/Construction/Brush Landfill: To comply with minimum standards each demolition/construction/brush landfill must meet the requirements of a Type III site plus no putrescible or hazardous waste shall be deposited in this type fill.
