The Federal Water Pollution Control Act of 1972, better known as the
Clean Water Act (CWA), established many of the current water quality
permits. The CWA was amended in 1987 to include storm water runoff as
point source pollution and therefore subject to the permitting process.
Aside from those initial years, there have never been such dramatic shifts

sand bags, bar screens to seeding, the permits have required various
activities to minimize erosion and enhance storm water quality. Until

As mentioned in previous newsletters, the EPA has published effluent
limitations for turbidity on construction sites. It is no longer acceptable to

developers and contractors will be required to monitor effluent turbidity
and take aggressive measures to reduce it.
On June 2nd, the TCEQ adopted eight total maximum daily loads (TMDLs) in
Greens Bayou. The TMDLs placed effluent limits for indicator bacteria
from water treatment facilities that discharge into the Bayou.
Additionally, the TMDLs also set bacterial effluent limits for storm water
runoff. This means that the regulated entities which convey storm water

The adoption of the turbidity rule and the bacterial TMDLs are not
unrelated. The EPA, under constant threat of lawsuits from
environmentalist groups, has begun adding definitive, measurable criteria
on the storm water permits. This means increased testing, increased
reporting, and, more than likely, increased enforcement.

among other things, that the permitting program should
focus on the impact of increased water volume rather than chemical
pollutants. If adopted, the old adage "the solution to pollution is
dilution" will no longer be valid. Rule-makers have hinted at requiring
new development to retain all storm water up to a 2-year, 24-hour
event. In Houston, that is approximately 5.5 inches within 24-hours.
