FORM: GSPSA 11193 Page 4 of 8 This form mast be completed by the appropriate DEM regional office and included as a part of the project submittal information. INSTRUCTIONS TO NC PROFESSIONAL ENGINEER: The classification of the downslope surface waters (the surface waters that any overflow from the facility would flow toward) in which these sewers will be constructed must be determined by the appropriate DEM regional office. Therefore, you are required, prior to submittal of the application package, to submit this form, with items 1 through 7 completed, to the appropriate Division of Environmental Management Regional Water Quality Supervisor (see page 8 of 8). At a minimum, you must include an 8.5" by IV' copy of the portion of a 7.5 minute USGS Topographic Map which shows the location of these sewers and the downslope surface waters in which they will be located. Identify the closest downslopc surface waters on the attached map copy. Once the regional office has completed the classification, reincorporate this completed page and the topographic map into the complete application form and submit the application package. 1.

In the case of contiguous service areas, evidence must be provided from the Utilities Commission acknowledging these areas are covered under an existing franchise. A properly executed Operational Agreement (original and one copy - form provided by DEM) must be submitted if the sewer extension will be serving single family residences, condominiums, mobile homes, or town houses and if the subject sewer extension is owned by the individual residents, a homeowners association, or a developer. h. The downslope surface waters classification must be determined by the appropriate DEM regional office, using page 5 of 8 of this form, prior to the submittal of the application package to the Water Quality Permits and Engineering Unit Once the regional office has completed the classification, page 5 of 8 should be reincorporated into the application package and the entire application package may then be submitted to Water Quality Permits and Engineering Unit A cover letter, which briefly describes the project, should be included with each application package. If necessary for clarity, fed free to include attachments to the application form. Such attachments will be considered as part of the application and should be numbered to correspond to the section to which they refer.
