On February 20, 2007, the department adopted changes to chapter 296-62 WAC, Part L – Atmospheres and Ventilation. Two sections were accidentally repealed in the rulemaking. This rulemaking corrected the error by putting the language back into the rule, which kept it as effective as the federal equivalent.WAC 296-62-100, Oxygen deficient atmospheres, and WAC 296-62-110, Ventilation was added back into chapter 296-62 WAC as WAC 296-62-135 and WAC 296-62-136. These changes will not result in additional compliance costs The changes were adopted 11/19/2007 and became effective on 1/2/2008.262.
