One of the basic requirements of the act relating to solid waste (chapter 431, Laws of 1989) is to have the owner or operator in responsible charge of a solid waste incinerator or solid waste landfill certified in the operation and maintenance of the facility. To achieve this, the department shall, to the greatest extent possible, rely on the certification standards and procedures developed by national organizations and the federal government. Certification under this act is available to all individuals who can meet the minimum qualifications for a given type of facility. Operating personnel not required to be certified by chapter 70.95D RCW are encouraged to become certified on a voluntary basis. note: All codes, standards, or rules cited in this chapter are available for inspection at the Department of Ecology, 300 Desmond Drive S.E., Lacey, Washington.
