US EPA Issues Effluent Limit Guideline
Rule for Construction Site Runoff
U S EPA issued the final rule for reg-
ulating construction site runoff on
December 1, 2009 in the Federal
Register. The final rule is a considerable
departure from the proposed rule, released
required but the turbidity limit does
not apply. The frequency and type of
sampling is still vague, but currently
suggested to be grab samples.
