Approval of this erosion and sedimentation control (ESC) plan does not constitute an approval of permanent road or drainage design (e.g. size and location of roads, pipes, restrictors, channels, retention facilities, utilities, etc.). 2. The implementation of these ESC plans and the construction, maintenance, replacement, and upgrading of these ESC facilities is the responsibility of the applicant/ESC supervisor until all construction is approved. 3. The boundaries of the clearing limits shown an this plan shall be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction. During the construction period, no disturbance beyond the clearing limits shall be permitted. The clearing limits shall be maintained by the applicant/ESC supervisor for the duration of construction. 4. The ESC facilities shown on this plan must be constructed prior to or in conjunction with all clearing and grading so as to ensure that the transport of sediment to surface waters, drainage systems, and adjacent properties is minimized. 5. The ESC facilities shown an this plan are the minimum requirements for anticipated site conditions. During the construction period, these ESC facilities shall be upgraded as needed for unexpected storm events and modified to account for changing site conditions (e.g. additional sump pumps, relocation of ditches and silt fences, etc.). 6. The ESC facilities shall be inspected daily by the applicant/ESC supervisor and maintained to ensure continued proper functioning. Written records shall be kept of weekly reviews of the ESC facilities during the wet season (Oct. 1 to April 30) and of monthly reviews during the dry season (May 1 to Sept. 30). 7. Any areas of exposed soils, including roadway embankments, that will not be disturbed for two days durin9 the season or seven days during the dry season shall be immediately stabilized with the approved ESC methods (e.g., seeding, mulching, plastic covering, etc.). wet 8. Any area needing ESC measures, not requiring immediate attention, shall be addressed within fifteen (15) days. 9. The ESC facilities on inactive sites shall be inspected and maintained a minimum of once a month or within 48 hours following a storm event. 10. At no time shall more than one (1) foot of sediment be allowed to accumulate within a catch basin. All catch basins and conveyance lines shall be cleaned prior to paving. The cleaning operation shall not flush sediment-laden water into the downstream system. 11. Stabilized construction entrances and roads shall be installed at the beginning of construction and maintained for the duration of the project. Additional measures, such as wash pads, may be required to ensure that all paved areas are kept clean for the duration of the project. 12. Any permanent fiow control facility used as a temporary settling basin shall be modified with the necessary erosion control measures and shall provide adequate storage capacity. If the facility is to function ultimately as an infiltration system, the temporary facility must be graded so that the bottom and sides are at least three feet above the final grade of the permanent facility. 13. Where straw mulch for temporary erosion control is required, it shall be applied at a minimum thickness of 2 to 3 inches. 14. Prior to the beginning of the wet season (Oct. 1), all disturbed areas shall be reviewed to identify which ones can be seeded in preparation for the winter rains. Disturbed areas shall be seeded within one week of the beginning of the wet season. A sketch map of those areas to be seeded and those areas to remain uncovered shall be submitted to the ODES inspector. The DDES inspector can require seeding of additional areas in order to protect surfuce waters, adjacent properties, or drainage facilities.

Approval of this erosion and sedimentation control (ESC) pion does nat constitute an approval of permanent road or drainage design (e.g. size and location of roads, pipes, restrictors, channels, retention facilities, utilities, etc.). 2, The implementation of these ESC plans and the construction, maintenance, replacement, and upgrading of these ESC facilities is the responsibility of the opplicant/ESC supervisor until all construction is approved. 3. The boundaries of the clearing limits shown on this plan shall be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction. During the construction period, no disturbance beyond the clearing limits shall be permitted. The clearing limits shall be maintained by the applicant/ESC supervisor for the duration of construction. 4. The ESC facilities shown on this pion must be constructed prior to or in conjunction with all clearing and grading so as to ensure that the transport of sediment to surface waters, drainage systems, and adjacent properties is minimized. 5. The ESC facilities shown on this pion are the minimum requirements for anticipated site conditions. During the construction period, these ESC facilities shall be upgraded as needed for unexpected storm events and modified to account for changing site conditions (e.g. additional sump pumps, relocation of ditches and silt fences, etc.). 6. The ESC facilities shall be inspected daily by the applicont/ESC supervisor and maintained to ensure continued proper functioning. Written records shall be kept of weekly reviews of the ESC facilities during the wet season (Oct. 1 to April 30) and of monthly reviews during the dry season (May 1 to Sept. 30). 7. Any areas of exposed soils, including roadway embankments, that will not be disturbed for two days durin9 the season or seven days during the dry season shall be immediately stabilized with the approved ESC methods (e.g., seeding, mulching, plastic covering, elc,). wet 8. Any area needing ESC measures, not requiring immediate attention, shall be addressed within fifteen (15) days. 9. The ESC facilities on inactive sites shall be inspected and maintained o minimum of once a month or within 48 hours following a storm event. 10. At no time shall more than one (1) foot of sediment be allowed to accumulate within o catch basin. All catch basins and conveyance lines shall be cleaned prior to paving. The cleaning operation shall not flush sediment-laden water into the downstream system. 11. Stabilized construction entrances and roods shall be installed at the beginning of construction and maintained for the duration of the project. Additional measures, such as wash pads, may be required to ensure that all paved areas are kept clean for the duration of the project. 12. Any permanent flow control facility used as a temporary settling basin shall be modified with the necessary erosion control measures und shall provide adequate storage capacity. If the facility is to function ultimately as an infiltration system, the ternporary facility must be graded so that the bottom and sides are at least three feet above the final grade of the permanent facility. 13. \\Aiere straw mulch for temporary erosion control is required, it shall be applied at o minimum thickness of 2 to 3 inches. 14. Prior to the beginning of the wet season (Oct. 1), all disturbed areas shall be reviewed to identify which ones can be seeded in preparation for the winter rains. Disturbed areas shall be seeded within one week of the beginning of the wet season. A sketch mop of those areas to be seeded and those areas to remain uncovered shall be submitted to the DOES inspector. The ODES inspector can require seeding of additional areas in order to protect surface waters, adjacent properties, or drainage facilities ..

Approval of this erosion and sedimentation control (ESC) plan does not constitute on approval of permanent road or drainage design (e.g. size and location of roads, pipes, restrictors, channels, retention facilities, utilities, etc.). 2. The implementation of these ESC plans and the construction, maintenance, replacement, and upgrading of these ESC facilities is the responsibility of the applicont/ESC supervisor until all construction is approved. 3. The boundaries of the clearing limits shown on this plan shall be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction. During the construction period, no disturbance beyond the clearing limits shall be permitted. The clearing limits shall be maintained by the opplicant/ESC supervisor for the duration of construction. 4. The ESC facilities shown on this pion must be constructed prior to or in conjunction with all clearing and grading so as to ensure that the transport of sediment to surface waters, drainage systerns, and adjacent properties is minimized. 5. The ESC facilities shown on this pion are the minimum construction period, these ESC facilities shall be upgraded account for changing site conditions (e.g. additional sump requirements for anticipated site conditions. as needed for unexpected storm events and pumps, relocation of ditches and silt fences, During the modified to etc.). 6. The ESC facilities shall be inspected daily by the opplicant/ESC supervisor and maintained to ensure continued proper functioning. Written records shall be kept of weekly reviews of the ESC facilities during the wet season (Oct. 1 to April 30) and of monthly reviews during the dry season (May 1 to Sept. 30). 7. Any areas of exposed soils, including roadway embankrnents, that will not be disturbed for two days durin9 the season or seven days during the dry season shall be immediately stabilized with the approved ESC methods (e.g., seeding, mulching, plastic covering, etc.). wet 8. Any area needing ESC measures, not requiring immediate attention, shall be addressed within fifteen (15) days. 9. The ESC facilities on inactive sites shall be inspected and maintained a rninimum of once a month or within 48 hours following a storm event. 10. At no time shall mare than one (1) foot of sediment be allowed to accumulate within a catch basin. All catch basins and conveyance lines shall be cleaned prior to paving. The cleaning operation shall not flush sediment-laden water into the downstream system. 11. Stabilized construction entrances and roads shall be installed at the beginning of construction and maintained for the duration of the project. Additional measures, such as wash pads, may be required to ensure that all paved areas are kept clean for the duration of the project. 12. Any permanent flow control facility used as a temporary settling basin shall be modified with the necessary erosion control measuros and shall provide adequate storage capacity. If the facility is to function ultimately as an infiltration system, the ternporary facility rnust be graded so that the bottorn and sides are at least three feet above the final grade of the permanent facility. 13. \\here straw mulch for temporary erosion control is required, it shall be applied at a minimum thickness of 2 to 3 inches. 14. Prior to the beginning of the we\ season (Oct. 1), all disturbed areas shall be reviewed to identify which ones can be seeded in preparation for the winter rains. Disturbed areas shall be seeded within one week of the beginning of the wet season. A sketch map of those areas to be seeded and those areas to remain uncovered shall be submitted to the DOES inspector. The ODES inspector can require seeding of additional areas in order to protect surface waters, adjacent properties, or drainage facilities.

Approval of this erosion and sedimentation control (ESC) pion does not constitute on approval of permanent road or drainage design (e.g. size and location of roads, pipes, restrictors, channels, retention facilities, utilities, etc.). 2. The implementation of these ESC plans and the construction, maintenance, replacement, and upgrading of these ESC facilities is the responsibility of the applicant/ESC supervisor until all construction is approved. 3. The boundaries of the clearing limits shown on this plan shall be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction. During the construction period, no disturbance beyond the clearing limits shall be permitted. The clearing limits shall be maintained by the applicant/ESC supervisor for the duration of construction. 4. The ESC facilities shown on this plan must be constructed prior to or in conjunction with all clearing and grading so as to ensure that the transport of sediment to surface waters, drainage systems, and adjacent properties is minimized. 5. The ESC facilities shown on this plan are the minimum requirements for anticipated site conditions. construction period, these ESC facilities shall be upgraded as needed for unexpected storm events and account for changing site conditions ( e.g. additional sump pumps, relocation of ditches and silt fences, During the modified to etc.). 6. The ESC facilities shall be inspected daily by the applicant/ESC supervisor and maintained ta ensure continued proper functioning. Written records shall be kept of weekly reviews of the ESC facilities during the wet season (Oct. 1 to April 30) and of monthly reviews during the dry season (May 1 to Sept. 30). 7.

Any area needing ESC measures, not requiring immediate attention, shall be addressed within fifteen (15) days. 9. The ESC facilities on inactive sites shall be inspected and maintained a minimum of once a month or within 48 hours following ., storm event. 10. At no time shall more than one (1) foot of sediment be allowed to accumulate within a catch basin. All catch basins and conveyance lines shall be cleaned prior to paving. The cleaning operation shall not flush sediment-laden water into the downstream system. 11. Stabilized construction entrances and roads shall be installed at the beginning of construction and maintained for the duration of the project. Additional measures, such as wash pads, may be required to ensure that all paved areas are kept clean for the duration of the project. 12, Any permanent flow control facility used as a temporary settling basin shall be modified with the necessary erosion control measures and shall provide adequate storage capacity. If the facility is to function ultimately as an infiltration system, the temporary facility must be graded so that the bottom and sides are at least three feet above the final grade of the p<;rmanent facility. 13. 'Mlere straw mulch for temporary erosion control is required, it shall be applied at a minimum thickness of 2 to 3 inches. 14. Prior to the beginning of the wet season (Oct. 1), all disturbed areas shall be reviewed to identify which ones con be seeded in preparation for the winter rains. Disturbed areas shall be seeded within one week of the beginning of the wet season. A sketch mop of those areas to be seeded and those areas to remain uncovered shall be submitted to the DDES inspector. The DDES inspector can require seeding of additional areas in order to protect surface waters, adjacent properties, or drainage facilities.

Approval of this erosion and sedimentation control (ESC) plan does not constitute an approval of permanent road or drainage deriign (e.g. size and location of roods, pipes, restrictors, channels, retention facilities, utilities, elc.). 2. The implementation of these ESC plans and the construction, maintenance, replacement, and upgrading of these ESC facilities is the responsibility of the applicant/ESC supervisor until all construction is approved. 3. The boundaries of the clearing limits shown on this plan shall be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction. During the construction period, no disturbance beyond the clearing limits shall be permitted. The clearing limits shall be maintained by the applicant/ESC supervisor for the duration of construction. 4. The ESC facilities shown on this plan must be constructed prior to or in conjunction with all clearing and grading so as to ensure that the transport of sediment to surface waters, drainage systems, and adjacent properties is minimized. 5. The ESC facilities shown on this plan are the minimum requirements for anticipated site conditions. During the construction period, these ESC facilities shall be upgraded as needed for unexpected storm events and modified to account for chunging site conditions (e.g. additional sump pumps, relocation of ditches and silt fences, etc.). 6.

Approval of tliis erosion and sedimentation control (ESC) plan does not constitute an approval of permanenl road or drainage desi9n (e.g. size and location of roads, pipes, restrictors, channels, retention facilities, utilities, etc.). 2. The implemen talion of these ESC plans and the construction, maintenance, replacement, and upgrading of lhese ESC facilities is the responsibility of the applicant/ESC supervisor until all construction is approved. 3. The boundari~s of the clearing limits shown on this plan shall be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction. During the construction period, no disturbance beyond the clearing limits shall be permitted. The clearing limits shall be maintained by the opplicant/ESC supervisor for the duration of construction. 4. The ESC facilities shown on this pion must be constructed prior to or in conjunction with all clearing and grading so as to ensure that the transport of sediment to surface waters, drainage systems, and adjacent properties is minimized. 5. The ESC facilities shown on this pion ore the m1n1mum requirements for anticipated site conditions. During the construction period, these ESC facilities shall be upgraded as needed for unexpected storm events and modified to account for changing site conditions (e.g. additional sump pumps, relocation of ditches and silt fences, etc.). 6. The ESC facilities shall be inspected doily by the opplicant/ESC supervisor and maintained to ensure continued proper functioning.

The implementation of these ESC plans ancl the construction, maintenance, replacement, and upgrading of these ESC facilities is the responsibility of the opplicont/ESC supervisor until all construction is approved, 3. The boundaries of the clearing limits shown on this plan shall be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction, During the construction period, no disturbance beyond the clearing limits shall be permitted, The clearing limits shall be maintained by the applicont/ESC supervisor for the duration of construction, 4, The ESC facilities shown on this plan must be constructed prior to or in conjunction with oil clearing and grading so as to ensure that the transport of sediment to surface waters, drainage systems, and adjacent properties is minimized. 5, The ESC facilities shown on this pion are the m1n1mum construction period, these ESC facilities shall be upgraded account for changing site conditions (e.g. additional sump requirements for anticipated site conditions. as needed for unexpected storm events and pumps, relocation of ditches and silt fences, During the modified to etc.). 6, The ESC facilities shall be inspected daily by the applicant/ESC supervisor and maintained to ensure continued proper functioning. Written records shall be kept of weekly reviews of the ESC facilities during the wet season (Oct. 1 to April 30) and of monthly reviews during the .dry season (Moy 1 to Sept. 30). 7, Any areas of exposed soils, including roadway embankments, that will not be disturbed for two days durin9 the season or seven days during the dry season shall be immediately stabilized with the approved ESC methods (e.g., .. seeding, mulching, plastic covering, etc.). wet 8, Any area needing ESC measures, not requiring immediate attention, shall be addressed within fifteen (15) days. 9. The ESC facilities on inactive sites shall be inspected and maintained a minimum of once a month or within 48 hours following o storm event. 10. At no time shall more than one (1) foot of sediment be allowed to accumulate within o catch basin, All catch basins and conveyance lines shall be cleaned prior to paving. The cleaning operation shall not flush sediment-laden water into the downstream system. 11. Stabilized construction entrances and roads shall be installed at the beginning of construction and maintained for the duration of the project. Additional measures, such as wash pads, may be required to ensure that all paved areas are kept clean for the duration of the project. 12.

REVISIONS: EROSION AND SEDIMENTATION CONTROL NOTES 1. Approval of this erosion and sedimentation control (ESC) plan does not constitute an approval of permane11t road or drainage design (e.g. size and location of roads, pipes, res\ric\ors, channels, retention facilities, utilities, elc.). z. The implementation of these ESC plans and the construction, maintenance, replacement, and upgrading of these ESC facilities is the responsibility of the applican\/ESC supervisor until all construction is approved. 3. The boundaries of the clearing limits shown on this plan shall be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction. During the construction period, no disturbance beyond the clearing limits shall be permitted. The clearing limits shall be maintained by the applicant/ESC supervisor for the duration of construction. 4. The ESC facilities shown on this plan must be constructed prior to or in conjunction with all clearing and grading so as to ensure \ha\ the transport of sediment to surface waters, drainage systems, and adjacent properties is minimized. 5. The ESC facilities shown on this plan are the minimum requirements for anticipated site conditions. During the construction period, these ESC facilities shall be upgraded as needed for unexpected storm events and modified to account for changing site conditions (e.g. additional sump pumps, relocation of ditches and silt fences, etc.). 6. The ESC facilities shall be inspected daily by the applicant/ESC supervisor and maintained to ensure continued proper functioning. Written records shall be kept of weekly reviews of the ESC facilities during the wet season (Oct. 1 to April 30) and of monthly reviews during the dry season (May 1 to Sept. 30). 7. Any areas of exposed soils, including roadway embankments, that will not be disturbed for two days durin9 the season or seven days during the dry season shall be immediately stabilized with the approved ESC methods (e.g., seeding, mulching, plastic covering, etc.). wet 8. Any area needing ESC measures, not requiring immediate attention, shall be addressed w'i\hin fifteen (15) days. 9. The ESC facilities on inactive sites shall be inspected and maintained a minimum of once a month or within 48 hours following a storm event. 10. At no time shall more than one (1) foot basins and conveyance lines shall be cleaned water into the downstream system. of sediment be allowed to accumulate within a catch basin. All catch prior to paving. The cleaning operation shall no\ flush sedimen I-laden 11. Stabilized construction entrances and roads shall be installed at the beginning of construction and maintained for the duration of the project. Additional measures, such as wash pads, may be required to ensure that all paved areas are kept clean for the duration of the project. 12. Any permanent flow control facility used as a temporary settling basin shall be modified with the necessary erosion control measures and shall provide adequate storage capacity. If the facility is to function ultimately as an infiltration system, the temporary facility must be graded so that the bottom and sides are at least three feet above the final grade of the permanent facility. 13. Where straw mulch far temporary erosion control is required, it shall be applied at a minimum thickness of 2 to 3 inches. 14. Prior to the beginning of the wet season (Oct. 1), all disturbed areas shall be reviewed to identify which ones can be seeded in preparation for the winter rains. Disturbed areas shall be seeded within one week of the beginning of the wet season, A sketch map of those areas \o be seeded and those areas to remain uncovered shall be submitted to the DDES jn,;pector. The DDES inspector can require seeding of additional areas in order to protect surface waters, adjacent properties, or drainage facilities. CATCH BASIN INSE_RT MAIN TE,\JAN<;:E STAt\JDAROS 1.
