Evaluation and
Assessment
There are three
primary evaluation and reporting requirements:
a. Evaluation of
program compliance, appropriateness of identified best
management practices, and progress toward achieving identified
measurable goals. (The permitting authority may determine
monitoring requirements in accordance with State monitoring
plans appropriate to the watershed; group monitoring is
encouraged.)
b. Records Maintenance: records required by the
permit must be kept for at least 3 years, but need only be
submitted to the permitting authority when specifically
requested. Records, including the storm water management
program, must be made available to the public at reasonable
times during regular business hours. A reasonable fee may be
assessed for copying, and members of the public may be
required to give advance notice, not to exceed two working
days.
c. Submission of annual reports to the permitting
authority for the first permit term. Subsequent submissions in
years two and four unless the permitting authority requires
more frequent reports. Reports must contain status of
compliance with permit conditions, assessment of the
appropriateness of identified best management practices and
progress towards achieving identified measurable goals for
each of the six minimum control measures. Results of
information collected and analyzed, including monitoring data,
during the reporting period. Summary of storm water activities
to be undertaken in the next reporting cycle. Change in any
identified measurable goals that apply to program elements.
Urban
Runoff:
Urban Runoff is
defined as the storm water surface runoff from highly
developed areas, which tends to contain heavy concentrations
of pollutants from vehicles, buildings, pavement and industry.
As reported in the most recent National Water Quality
Inventory reports, urban runoff is a leading source of water
quality impairments to the limited sources of surface water in
the country. From 1977-82, the United States Environmental
Protection Agency (EPA) funded the Nationwide Urban Runoff
Program (NURP) and other studies, which showed that urban
storm water runoff was contaminated. The NURP and other
studies findings provided the basis for EPA to regulate storm
water runoff. The following damages are attributed to urban
runoff:
·
Changes in urban stream hydrology: increased
floods, increase in runoff annual volume and higher velocities
in stream flow.
·
Changes in channel morphology: channel widening
and down cutting, stream bank erosion, changes in sediment
grain size, different scour patterns and channel modification
or relocation.
·
Changes in urban stream quality
·
Changes in groundwater: reduced infiltration,
reduced recharge, lost soil filtering and increased
contamination.
