The regulation:
(i) is necessary for the protection of public health, safety, and welfare or for the economical performance of important governmental functions;
(ii) minimizes the economic impact on small businesses in a manner consistent with the stated objectives of applicable law; and
(iii) is clearly written and easily understandable.
Repeal these regulations and start fresh with performance requirements based on standard engineering practices that serve to proctect public health, safety, and welfare.
