Document #10609, effective 6-1-14, readopted with amendments and renumbered former rules Env-Ws 370.01 through Env-Ws 370.05 in Part Env-Ws 370 , entitled "General Design Standards: Serving 1,000 or More People", under a new subtitle as Env-Dw 402.01 through Env-Dw 402.05, within a new Part Env-Dw 402. The redesignation from subtitle Env-Ws to subtitle Env-Dw was done pursuant to a rules reorganization plan for Department rules approved by the Director of the Office of Legislative Services on 9-7-05. Document #10609 also readopted with amendments and renumbered former rule Env-Ws 344.01, entitled "Treatment of Contaminants by Flow Mix", as Env-Dw 402.08.

These rules did not expire on 11-30-13 since they were extended pursuant to RSA 541-A:14-a until replaced by the rules in Document #10609, effective 6-1-14.
