     Statute Being Implemented: Chapter 49.17 RCW.

     Summary: See Purpose above.

     Reasons Supporting Proposal: See Purpose above.

     Name of Agency Personnel Responsible for Drafting: Tracy Spencer, Tumwater, (360) 902-5530; Implementation and Enforcement: Michael A. Silverstein, Tumwater, (360) 902-5495.

     Name of Proponent: Department of Labor and Industries, governmental.

     Rule is not necessitated by federal law, federal or state court decision.

     Explanation of Rule, its Purpose, and Anticipated Effects: See Purpose above.

     Proposal Changes the Following Existing Rules: The hazardous waste operations and TSD facilities rule, in chapter 296-62 WAC, is being rewritten, reorganized, renamed, and renumbered as chapter 296-843 WAC, Hazardous waste operations, for clarity and ease of use for employers and employees. We are also revising two provisions of the rule as a result of a "not-at-least-as-effective-as" (NALAEA) OSHA determination. A note will be added to chapter 296-62 WAC, Part P, Hazardous Waste Operations and Treatment, Storage, and Disposal Facilities stating the requirements will only apply to agriculture.

     No small business economic impact statement has been prepared under chapter 19.85 RCW. The department considered whether these proposed rules are subject to the Regulatory Fairness Act and determined that they do not require a small business economic impact statement because the proposed changes are exempt by law (see RCW 19.85.025 referencing RCW 34.05.310(4)) from the small business economic impact requirement.

     RCW 34.05.328 applies to this rule adoption. This rule is a significant legislative rule, however it is exempt under RCW 34.05.328 (5)(b) since it only corrects typographical errors and clarifies language without changing its effect. The proposal does not increase requirements.

     Hearing Location: Department of Labor and Industries Building, Rooms S117 and S118, 7273 Linderson Way S.W., Tumwater, WA, on August 26, 2003, at 9:00 a.m.

     Assistance for Persons with Disabilities: Contact Sally Elliott by August 20, 2003, at (360) 902-5484.

     An example of a situation that results in an incidental release:

     A tanker truck is receiving a load of hazardous liquid when a leak occurs. The driver knows the only hazard from the liquid is minor skin irritation. The employer has trained the driver on procedures and provided equipment to use for a release of this quantity. The driver puts on skin protection and stops the leak. A spill kit is used to contain, absorb, and pick up the spilled material for disposal.

     Material safety data sheet (MSDS)

     Written, printed, or electronic information (on paper, microfiche, or on-screen) that informs manufacturers, distributors, employers or employees about a hazardous chemical, its hazards and protective measures as required by chapter 296-839 WAC, Content and distribution of material safety data sheets (MSDSs) and label information.

     Oxygen deficiency

     An atmosphere where the percentage of oxygen by volume is less than 19.5%.

     Permissible exposure limit (PEL)

     Permissible exposure limits (PELs) are employee exposures to toxic substances or harmful physical agents that must not be exceeded. PELs are specified in applicable WISHA rules.

     Published exposure level

     Exposure limits published in "National Institute for Occupational Safety and Health (NIOSH) Recommendations for Occupational Safety and Health" (DHHS publication #92-100, 1992).

     If an exposure limit is not published by NIOSH, then "published exposure level" means the exposure limits published by the American Conference of Governmental Industrial Hygienists (ACGIH) in "TLVs and BEIs-Threshold Limit Values for Chemical Substances and Physical Agents" (1999 edition).

     Postemergency response

     The stage of the emergency response where the immediate threat from the release has been stabilized or eliminated, and cleanup of the site has started. For more information, see the definition for "emergency response."

     Site safety and health supervisor (or official)

     The individual present at a hazardous waste site who is responsible to the employer and has the authority and knowledge necessary to establish the site-specific health and safety plan and verify compliance with applicable safety and health requirements.

     Site work zones

     Zones established at a hazardous waste site before clean-up work begins to control work on the site and access to the site. The work zones are: Exclusion zone, contamination reduction zone, and clean zone.

     Uncontrolled hazardous waste site

     An area identified as an uncontrolled hazardous waste site by a governmental body, whether federal, state, local, or other, where an accumulation of hazardous substances creates a threat to the health and safety of individuals or the environment or both. Examples include: Former municipal, county, or state landfills, locations where illegal or poorly managed waste disposal has taken place, or property of generators or former generators of hazardous substance waste (surface impoundments, landfills, dumps, and tank or drum farms).
