Technical Report 55 method with rainfall data will be used by the Environmental Compliance and Protection
Organization to estimate flows. Flow will be reported in millions of gallons per day (mgd) as estimated daily
maximum values. No flow field measurements are required.

likely to affect the quality of storm water discharges are identified, best management practices that can be
used to control the entry of pollutants into storm water discharges are developed, and methods for
implementing pollution prevention practices are devised. Analytical parameters to be monitored at each
storm drain as part of the ETTP SWP3 are chosen based upon a review of available analytical data from
previous storm water sampling efforts and knowledge of past processes and practices at ETTP.
Storm water discharges from ETTP are fully characterized during each NPDES permitting period and
in accordance with storm water pollution prevention plans. The NPDES permit can be issued for as long
as 5 years, although the current ETTP site storm water permit was issued for a 4 year period so that the
ETTP permit expiration date would be consistent with the state of Tennessee watershed schedule for the
area of the state in which ETTP is located.
The Biological Monitoring and Abatement program (BMAP) is also a requirement of NPDES Permit
No. TN0002950. Its purpose is to assess the ecological health of the ETTP’s receiving streams and ponds.
The BMAP consists of three tasks: toxicity monitoring, bioaccumulation monitoring, and ecological
surveys of in-stream communities (both fish and benthic macroinvertebrates). The BMAP monitoring
program is conducted by the Oak Ridge National Laboratory (ORNL) Environmental Sciences Division
(ESD) under the direction of the ETTP EC&P Organization. Details of the monitoring are provided in the
most current revision of BJC/OR-763, East Tennessee Technology Park Biological Monitoring and
