TO: REGIONAL WATER QUALITY SUPERVISOR
Please provide me with the classification of the surface waters identified in number 5 below and on the
attached map segment:
Name of surface waters: Old Field Swam
Classification (as established by the Environmental Management Commission): C Sw
Proposed Classification, if applicable: N/A
Signature of regional officepersonnel:
INSTRUCTIONS TO ENGINEER
In order to determine whether provisions for dual or standby power may be required for the subject facility,
the classification of the closest downslope surface waters (the surface waters that any overflow from the facility
would flow toward) must be determined. You are required to submit this form, with items 1 through 10
completed, to the appropriate Division of Environmental Management Regional Water Quality Supervisor (see
attached listing). At a minimum, you must include an 8.5" by I V copy of the portion of a 7.5 minute USGS
Topographic Map which shows the subject surface waters. You must identify the location of the facility and the
closest downslope surface waters (waters for which you are requesting the classification) on the submitted map
copy. The application may not be submitted until this form is completed and included with the submittal.
