Mr. Martin W. Inderbitzen May 27, 1986 Page 3 T (4) 'Facility structures" means any buildings and sheds or; utility or drainage lines on the facility. (5),'Lower explosive limit' means the lowest percent by volume of a mixture of explosive gases which will propagate a flame in air at 25 degrees C and atmospheric pressure. State Regulations State regulations are not as specific as the federal regulations. The California Administrative Code, Title 14, Division 7, Chapter 3, Article 7, Section 17705 states: Gas Control. Where the Enforcement Agency, the local fire control authority, or the Board has cause to believe a hazard or nuisance may be created by landfill decomposition gases, they shall so notify the owner. Thereafter, the site owner shall cause the site to be monitored for presence and movement of gases, and shall take necessary action to control such gases. The site owner shall inform the operator of any actions ordered by the Enforcement Agency, local fire control authority or the Board concerning gas control methods. The monitoring program shall be developed pursuant to the specifications of the above agencies. The site owner shall provide for continuation of the program after the completion of the landfill. The monitoring program shall not be discontinued until authorized to do so in writing by the requiring agency. Results of the monitoring shall be submitted to the appropriate agencies. If monitoring indicates methane gas movement away from the site, the owner shall, within a period of time specified by the requiring agency, construct a gas control system approved by that agency. The agency may waive this requirement if satisfactory evidence is presented indicating that adjacent properties are safe from hazard or nuisance caused by methane gas movement. The operator shall duly inform the disposal site owner of possible landfill gas problems. Several other regulations regarding hazardous gas are the California Administrative Code, Article 4, Section 1532 that requires that 'confined spaces" be checked for the presence of combustible or dangerous gas prior to the entry of workmen. A "confined space" is defined as a storm drain, sewer, vault, manhole, or other structure which could permit the accumulation of dangerous gases. Article 10, Section 6810 of the Code requires that combustible gas indicators be made available and maintained for use in locations where combustible gases may be present or are likely to be present.
