Adopted 11-03-94
(Revised 02-09-95)

100 GENERAL

101 APPLICABILITY: The provisions of this rule shall apply to all solid waste disposal sites that have received more than 500,000 tons of decomposable solid waste. The refuse density shall be assumed to be 1,300 pounds per cubic yard and the decomposable fraction shall be assumed to be 70 percent by weight unless other site specific factors are submitted to and approved by the Air Pollution Control Officer (APCO). The provisions of this rule apply only to facilities located in the Sacramento Valley Air Basin portion of Placer County, as defined by California Code of Regulations, Title 17, Division 3, Chapter 1, Subchapter 1.5, Article 1, Section 60106.

102 EXEMPTIONS

200 DEFINITIONS

201 ACTIVE LANDFILL: Any solid waste disposal site which received waste at any time during the past 6 months.

202 BASELINE CONDITION: A landfill is in its baseline condition when no leaks exist at:

203 CONTROL DEVICE: Any device that disposes of the collected gas by one or more of the following means: combustion; gas treatment and subsequent sale; sale and processing offsite; other equivalent methods.

204 DECOMPOSABLE SOLID WASTE: Any material which is not Non-decomposable Inert Solid Waste.

205 DESTRUCTION/TREATMENT EFFICIENCY: A measure of the ability of the control device to combust, transform, or otherwise prevent the emissions to the atmosphere of non-methane organic compounds in landfill gas.

206 ENERGY RECOVERY EQUIPMENT: Any equipment that uses landfill gas to produce useful energy.

207 EXCAVATION: Any movement of landfill cover that triggers the notification requirements of any government agency.

208 FINAL COVER: Cover material that is applied on areas where additional cells are not to be constructed, and therefore, must be highly resistant to erosion.

209 GAS COLLECTION SYSTEM: A series of collectors and associated piping and equipment which provides a gas transfer path to the control device.

210 INTERMEDIATE COVER: Cover material that is applied on areas where additional cells are not to be constructed for extended periods of time, and therefore, must resist erosion for a longer period of time than daily cover.

211 LANDFILL: Any location within a solid waste disposal site used for the permanent disposal of waste where the organic portion of the waste is subject to natural processes of aerobic and anaerobic decomposition.

212 LANDFILL GAS: Any untreated, raw gas derived through the decomposition of organic waste deposited in a solid waste disposal site, from the evolution of volatile species in the waste, or from chemical reactions of substances in the waste.

213 LEAK: Any point where the concentration of total organic compounds measured as methane exceeds 1000 ppm by volume except non-repeatable momentary readings.

214 LEAK FREE: The absence of the evidence of "Leaks".

215 NON-DECOMPOSABLE INERT SOLID WASTE: Materials which do not degrade biologically to form landfill gas. Examples include, but are not limited to, earth, rock, concrete, clay products, inert tailings, plaster board, glass, inert slag, asbestos, and demolition materials containing less than 10 percent by volume wood and metals.

216 NON-METHANE ORGANIC COMPOUNDS (NMOC): Any compound in a gaseous state at standard temperature and pressure which contains at least one atom of carbon except: methane, carbon monoxide, carbon dioxide, metallic carbides, carbonates, and carbonic acid.

217 NON-REPEATABLE, MOMENTARY READINGS: Indications of the presence of organic gasses using a detector meeting the apparatus requirements of EPA Method 21 which persist for less than 5 seconds and do not recur when the sampling probe is placed in the same location for at least twice the response time of the instrument.

218 OWNER: For the purpose of this rule the owner is the fee owner of a solid waste disposal site and the person who through lease, or other arrangement with the fee owner is responsible for complying with all applicable federal, state and local requirements for landfill gas emissions, provided that upon the expiration of such person's responsibility for landfill gas emissions under such lease or other arrangement the fee owner shall be deemed the owner. Where specific requirements of this rule apply to equipment at the solid waste disposal site that is owned or operated by a second party other than the fee owner, the second party shall be deemed the owner for the purpose of such rule requirements as they relate to such equipment.

219 PERIMETER: The outer boundary of the solid waste disposal site property.

220 QUARTER: The months that define a "quarter" are: January, February and March (1st quarter ends on March 31); April May and June (2nd quarter ends on June 30); July, August and September (3rd quarter ends on September 30); October, November and December (4th quarter ends on December 31).

221 SOLID WASTE: All putrescible and non-putrescible solid, semisolid, and liquid wastes, including garbage, trash, refuse, paper, rubbish, ashes, industrial waste, manure, vegetable or animal solid and semisolid wastes, sludge, and other discarded solid and semisolid wastes.

222 SOLID WASTE DISPOSAL SITE: Includes the place, location, tract of land, area, or premises in use, intended to be used, or which has been used for the landfill disposal of wastes and/or the evaporation of liquid chemical waste.
