S&ME presented the requested revisions pertaining to Control Measures for each entity in the 3 Storm Water Management Program Revisions S&ME No. 1824-13-021 Gadsden-Etowah MS4 May 2013 Annual Report dated March 28, 2013 and again in this report. Additionally, S&ME is presenting revisions to eleven (11) of the monitoring point locations. 2. MONITORING 2.1 Monitoring Locations Eighteen primary monitoring locations were identified in the 2012 SWMP for determining compliance of the Gadsden-Etowah MS4 with the 2008 TMDL for phosphorous. The locations were selected along the river at points determined to be representative of the typical land uses in the subwatersheds. Prior to the first round of sampling in March 2013, several monitoring points were relocated due to problems with access. The revised coordinates are included in Table 2. Specific details regarding each monitoring point location are presented below. 1. HB 3 - To allow for sampling from a boat, monitoring point HB 3 was relocated 0.34 mile southwest. The revised location also accounts for additional watershed area. 2. SME 3 - To allow for sampling from a boat, monitoring point SME 3 was relocated 0.39 mile northwest to where Coal Creek enters Neely Henry Lake. 3. GD 3 - Due to access difficulties, monitoring point GD 3 was relocated approximately 1.55 miles east. This location also better characterizes discharges from the development along Tidmore Street. 4. GD 7 - Based on input from the City of Gadsden Water Works, monitoring point GD 7 was relocated approximately 0.17 mile southwest, from Broad Street to Walnut Street. The revised location is near an outfall from the downtown Gadsden storm sewer directly to Neely Henry Lake. 5. CO 15 - Due to access difficulties, monitoring point CO 15 was relocated approximately 0.35 mile north. 6. CO 14 - Due to access difficulties, monitoring point CO 14 was relocated 0.15 mile northeast. 7. GD 12 - Due to low stream flow, monitoring point GD 12 was relocated 0.11 mile northwest to an unnamed tributary of Neely Henry Lake that has a larger contributing watershed with similar land use. 4 Storm Water Management Program Revisions S&ME No. 1824-13-021 Gadsden-Etowah MS4 May 2013 8. SS 5 - To allow for sampling from a boat, monitoring point SS 5 was relocated 0.36 mile north. 9. RC 2 - Due to access difficulties, monitoring point RC 2 was relocated 0.50 mile west upstream in Horton Creek. 10. SS 14 - Due to access difficulties, monitoring point SS 14 was relocated 0.32 mile east. 11. RC 14 - Monitoring point RC 14 was relocated 0.89 mile south to allow for sampling from a boat. The revised location also monitors discharges from Rook Creek and another unnamed tributary to the Coosa. The locations of monitoring points GD 5, GD 6, SME 2, SME 1, GD 8, AT 5, and SS 13 were
