B. Continuation of the Expired General Permit If this permit is not reissued or replaced prior to the expiration date, it will be administratively continued in accordance with the ADEM Administrative Code Chapter 335-6-6 and remain in force and effect if the Permittee submits an updated and complete NOI meeting the requirements of Part II.C. at least 30 days prior to the expiration of this permit. Any Permittee who was granted permit coverage prior to the expiration date will automatically remain covered by the continued permit until the earlier of: 1. Reissuance or replacement of this permit, at which time the Permittee must comply with the Notice of Intent conditions of the new permit to maintain authorization to discharge; or 2. Issuance of an individual permit; or 3. A formal permit decision by the Department not to reissue this general permit, at which time the Permittee must seek coverage under an alternative general permit or an individual permit. C. Contents of the Notice of Intent (NOI) 1. The NOI shall include: (a) A general description of the construction activity for which coverage is desired, which shall be in sufficient detail to allow the Department to determine that the stormwater and non-stormwater discharges are included in the authorized discharges category of this general permit. (b) The latitude and longitude to the nearest second of the entrance to the construction site and each point of discharge for which coverage under this general permit is desired. For the purposes of this requirement the entrance to the construction site will be identified as the primary point of access by normal vehicle traffic. For linear projects, the latitude and longitude to the nearest second should be provided for the starting and ending point of the project boundaries. (c) Identification of the waterbodies receiving discharges for which coverage under this general permit is desired. (d) The correct fee pursuant to ADEM Admin. Code R. 335-1. (e) A portion or copy of a recent U.S. Geological Survey map showing the site location. (f) A contact person, address and phone number for the site to be covered under the general permit. 6 (g) For priority construction sites, as defined in Part V, the NOI must be accompanied by a copy of the CBMPP prepared and certified by a QCP as required by Part III.C. (h) The number of estimated disturbed acres and total site acreage (i) The estimated start and completion dates of project. 2. The NOI shall be signed by a person meeting the requirements for signatories under ADEM Admin. Code r. 335-6-6-.09 and the person signing the NOI shall make the certification required for submission of documents under ADEM Admin Code r. 335-6-6-.09. 3. The NOI shall be signed by a QCP and shall have the following certification statement: “I certify under penalty of law that a comprehensive Construction Best Management Practices Plan (CBMPP) for the prevention and minimization of all sources of pollution in stormwater and authorized related process wastewater runoff has been prepared under my supervision for this site/activity, and associated regulated areas/activities. The CBMPP meets the requirements of this permit and if properly implemented and maintained by the operator, discharges of pollutants in stormwater runoff can reasonably be expected to be effectively minimized to the maximum extent practicable according to the requirements of ADEM Administrative Code Chapter r.335-6-6-.23 and this Permit. The CBMPP describes the erosion and sediment control measures that must be fully implemented and regularly maintained as needed at the permitted site in accordance with sound sediment and erosion control practices to ensure the protection of water quality.” D. Submittal of Documents The Permittee must complete and submit the NOI electronically, using the Department’s eNOI system, unless the Permittee submits in writing valid justification as to why the electronic submittal process cannot be utilized and the Department approves in writing the utilization of hard copy submittals. The eNOI system can be accessed at the following link https://app.adem.alabama.gov/eNOI/Default.aspx. Permit requests for initial issuance and modifications of the existing permit should all be submitted through the eNOI system. All other documents required to be submitted to the Department by this general permit shall be delivered to the following address: Alabama Department of Environmental Management Water Division Stormwater Management Branch Post Office Box 301463 (Zip Code: 36130-1463) 1400 Coliseum Boulevard (Zip Code: 36110-2059) Montgomery, Alabama E. Additional Permittees Under a Single NOI Multiple operators conducting regulated land disturbances in a common plan of development may jointly submit an NOI. An NOI covering multiple operators must include a site plan clearly describing each operator’s areas of operational control. F. Authorization to Discharge 1. Except as otherwise limited by Part II.F.2 or II.F.3, the operator is authorized to discharge in accordance with the requirements of this permit upon the Department’s receipt of a complete and timely NOI which meets the requirements of this permit and ADEM Admin. Code r. 335-6-6-.23. 7 2. Coverage under this permit is conditionally granted, and the requirement to submit an NOI is suspended for governmental agencies and utilities for construction activity associated with immediate and effective emergency repairs and response to natural disasters, human health or environmental emergencies, or to avert/avoid imminent, probable, or irreparable harm to the environment or severe property damage. The operator or controlling/participating federal, State, or local government agencies/entities conducting emergency construction activity shall document the emergency condition, ensure compliance with the requirements of this permit to the extent possible, and shall notify the Department as promptly as possible regarding the occurrence of the emergency construction disturbance and measures that have been implemented and are being implemented to protect water quality. Unless the requirement to obtain a permit pursuant to the requirements of this permit are suspended or voided by the Director on a categorical or individual emergency basis, the operator shall submit the appropriate project information, NOI, and the required application fee for construction or reconstruction activity after emergency repairs have been accomplished, according to a schedule acceptable to the Department. 3. For priority construction sites, the operator is authorized to discharge thirty (30) days from the Department’s receipt of a complete and technically adequate NOI and CBMPP meeting the requirements of Parts II.C. and III.E, unless, within thirty (30) days from the Department’s receipt of the NOI, the Department notifies the operator that additional time is needed to review the NOI and CBMPP. Where the operator receives such notification from the Department, that operator may not discharge until the Department formally acknowledges receipt of a complete and technically adequate NOI and CBMPP. 8 PART III Stormwater Pollution Prevention Requirements The stormwater control requirements in this Part are the technology-based, non-numeric effluent limitations and conditions that apply to all discharges from construction projects eligible for coverage under this permit. These requirements apply the national effluent limitations guidelines and new source performance standards found at 40 CFR Part 450. Where the requirements in this Part are stricter than any corresponding Federal, State, or local requirements, the requirements in this permit take precedence. A. Erosion Controls and Sediment Controls The Permittee shall design, install, and maintain effective erosion controls and sediment controls, appropriate for site conditions to, at a minimum: 1. Minimize the amount of soil exposed during construction activity through the use of project phasing or other appropriate techniques; 2. Provide and maintain a 25 foot natural riparian buffer around surface waters as discussed in detail in Part III.B.; 3. Control stormwater volume and velocity within the site to minimize soil erosion; 4. Implement measures or requirements to achieve the pollutant reductions consistent with a TMDL finalized or approved by EPA. Applicable TMDLs are located and/or can be accessed at http://adem.alabama.gov/programs/water/approvedTMDLs.htm 5. Control stormwater discharges, including both peak flowrates and total stormwater volume, to minimize channel and streambank erosion and scour in the immediate vicinity of discharge points; 6. Minimize the disturbance of steep slopes, as defined by Part V; 7. Minimize sediment discharges from the site; 8. Minimize the generation of dust through the appropriate application of water or other dust suppression techniques; 9. Minimize all stream crossings; 10. Stabilize all construction entrances and exits; and minimize off-site tracking of sediment from vehicles; 11. Where applicable, install storm drain inlet protection measures to further prevent sediment discharges; 12. Direct stormwater to vegetated areas to increase sediment removal and maximize stormwater infiltration, unless infeasible; and 13. Minimize soil compaction and, unless infeasible, preserve topsoil. 14. Additional Design Requirements (a) Sediment control measures, erosion control measures, and other site management practices must be properly selected based on site-specific conditions, must meet or exceed the technical standards outlined in the Alabama Handbook and the site-specific CBMPP prepared in accordance with Part III.D. (b) Unless specified otherwise by the Alabama Handbook, sediment control measures, erosion control measures, and other site management practices shall be designed and maintained to minimize erosion and maximize sediment removal resulting from a 2-year, 24-hour storm event. (c) The Permittee is encouraged to design the site, the erosion prevention measures, sediment controls measures, and other site management practices with consideration of minimizing stormwater runoff, both 9 during and following construction, including facilitating the use of low-impact development (LID) and green infrastructure. B. Provide Natural Riparian Buffers or Equivalent Sediment Controls Natural riparian buffer requirements apply to all waters of the state adjacent to construction sites or contained within their overall project boundary. A 25-foot natural riparian buffer zone adjacent to all waters of the state at the construction site shall be preserved, to the maximum extent practicable, during construction activities at the site. The natural riparian buffer should be preserved between the top of stream bank and the disturbed construction area. The water quality buffer zone aids in the protection of waters of the state (e.g., perennial and intermittent streams, rivers, lakes, wetlands) located within or immediately adjacent to the boundaries of the project. Natural riparian buffers are not primary sediment control measures and should not be relied on as such. The natural riparian buffer requirement only applies to new construction sites. 1. Compliance Alternatives (a) Provide and maintain a 25-foot undisturbed natural riparian buffer; or (i) If land disturbances are located 25 feet or further from surface water, then compliance with this alternative has been achieved. (ii) Rehabilitation and enhancement of a natural riparian buffer is allowed, if necessary, for improvement of its effectiveness of protection of the waters of the state. (iii) Any preexisting structures (e.g., buildings, parking lots, roadways, utility lines, structures, impervious surfaces) are allowed in the natural riparian buffer; provided the Permittee retains and protects from disturbance any additional natural buffer area contained within the natural riparian buffer but outside the preexisting structures footprint. (b) Provide and maintain an undisturbed natural riparian buffer that is less than 25 feet and is supplemented by additional erosion and sediment controls, which in combination achieves the sediment load reduction equivalent to a 25-foot undisturbed natural riparian buffer; or (c) If it is infeasible to provide and maintain an undisturbed natural riparian buffer of any size, the Permittee must implement erosion and sediment controls that achieve the sediment load reduction equivalent to a 25-foot undisturbed natural riparian buffer. (d) All discharges from the area of earth disturbance to the natural riparian buffer must first be treated by the site’s erosion and sediment controls, and use velocity dissipation devices if necessary to prevent erosion caused by stormwater within the natural riparian buffer. (e) All compliance alternatives must be documented in the CBMPP and comply with all requirements. The natural riparian buffer boundary should be indicated on the site plan. (f) Compliance alternatives must be maintained throughout the duration of permit coverage. (g) All natural riparian buffer areas should be delineated, and clearly marked off with flags, tape, or similar marking device. 2. Construction activities at sites that have been permitted prior to April 1, 2016, are exempt from the requirements of this Part III.B. Confirmation of permit coverage prior to April 1, 2016, must be submitted with the NOI. 3. If there is no discharge of stormwater to waters of the state through the areas between the construction site and any waters of the state located within 25 feet of the construction site, compliance with this requirement is achieved. 4. Where no natural riparian buffer exists due to preexisting development disturbances (e.g., buildings, parking lots, roadways, utility lines, structures, impervious surfaces) that occurred prior to the initiation of planning for the current development of the site, the Permittee is not required to comply with the requirements in this section, unless portions of the preexisting development will be removed. 10 5. Where some natural riparian buffer exists but portions of the area within 25 feet of the waters of the state are occupied by preexisting development disturbances (e.g., buildings, parking lots, roadways, utility lines, structures, and impervious surfaces), the Permittee is required to comply with the requirements in this section. Only the portion of the buffer zone that contains the footprint of the existing “structure” is exempt from the natural riparian buffer. Activities necessary to maintain uses are allowed provided that no additional vegetation is removed from the natural riparian buffer. 6. For “linear construction projects”, the Permittee is not required to comply with the requirements in this section if site constraints (e.g., limited right-of-way) prevent the Permittee from meeting any of the compliance alternatives provided that, to the extent practicable, disturbances within 25 feet of the water of the state are limited and/or supplemental erosion and sediment controls to treat stormwater discharges from earth disturbances within 25 feet of the waters of the state are provided. It must be documented in the CBMPP as to why compliance with this section is infeasible, and describe any buffer width retained and/or supplemental erosion and sediment controls installed. 7. The following disturbances within 25 feet of a water of the state are exempt from the requirements in this Part: (a) Construction approved under a CWA Section 404 permit; or (b) Construction of a water-dependent structure or water access area (e.g., pier, boat ramp, seawall, bridge, drainage structure, trail, etc.) C. Soil Stabilization Final stabilization of disturbed areas must, at a minimum, be initiated immediately whenever any clearing, grading, excavating or other earth disturbing activities have permanently ceased on any portion of the site. Temporary stabilization of disturbed areas must be initiated immediately whenever work toward project completion and final stabilization of any portion of the site has temporarily ceased on any portion of the site and will not resume for a period exceeding thirteen (13) calendar days. D. Pollution Prevention Measures The Permittee must design, install, implement, and maintain effective pollution prevention measures to minimize the discharge of pollutants. At a minimum, such measures must be designed, installed, implemented and maintained to: 1. Minimize the discharge of pollutants from equipment and vehicle washing, wheel wash water, concrete washout, and other wash waters. Wash waters must be treated in a sediment basin or alternative control that provides equivalent or better treatment prior to discharge; (a) Liquid waste shall not be directly discharged into storm sewers. (b) Washout and cleanout activities should be located as far away as possible from surface waters, natural buffer areas, stormwater inlets, and conveyances. 2. Minimize the exposure of building materials, building products, construction wastes, trash, landscape materials, fertilizers, pesticides, herbicides, detergents, sanitary waste and other materials present on the site to precipitation and to stormwater; 3. Minimize the discharge of pollutants from any spills and leaks from, including but not limited to vehicles; mechanical equipment; chemical storage; and refueling activities; and 4. Use of polymers, flocculants, or other treatment chemicals at the site may only be applied where treated stormwater is directed to a sediment control prior to discharge. 11 E. Construction Best Management Practices Plan (CBMPP) 1. Except as provided by Part II.F.2, construction activity may not commence until a CBMPP has been prepared in a format acceptable to the Department and certified by a QCP as adequate to meet the requirements of this permit. 2. The NOI and CBMPP must be prepared in accordance with the requirements of this permit by the QCP prior to commencing construction at a new construction site or prior to continued construction at an existing construction site, or as otherwise required by the Director. 3. The Permittee shall properly implement and regularly maintain the controls, practices, devices, and measures specified in the CBMPP. 4. The CBMPP shall include: (a) A general description of the construction site activity, including: (i) The function of the construction site activity (e.g. residential subdivision, shopping mall, highway, etc.); and (ii) Identification of all known operators of the construction site, and the areas of the site over which each operator has control; (b) A description of the intended sequence of major activities which disturb soils, including but not limited to, grubbing, excavation, and/or grading; (c) Estimates of the total area expected to be disturbed by grubbing, excavation, and/or grading, including offsite borrow and fill areas (if areas are to be included in permit coverage); (d) A detailed description (including but not limited to site specific dimensions, storage capacity, and drainage calculations are required for engineered BMPs) of the erosion controls, sediment controls, and management practices to be implemented at the site during each sequence of activity in accordance with Part III.A; (e) A clear outline and identification of the 25-foot natural riparian buffer for all sites that discharge directly to waters of the state and where a water of the state lies within the boundaries of the project; (f) A detailed description of controls needed to meet State water quality standards, waste load allocations or other measures necessary for consistency with applicable TMDLs finalized or approved by EPA; (g) A detailed description of BMPs needed to prevent or eliminate discharges of sediment and other pollutants of concern from priority construction sites; (h) A description of temporary and permanent stabilization practices, including a schedule and/or sequence for implementation; (i) A description of energy or flow velocity dissipation devices at discharge locations and along the length of any outfall channel; (j) Identification of all allowable sources of non-stormwater discharges listed in Part I.B.2, except for flows from fire fighting activities that are or may be combined with stormwater discharges associated with construction activity at the site; (k) A description of the pollution prevention measures used to manage non-stormwater discharges; (l) A description of the best management practices to be installed during site construction and operated and maintained following final stabilization at sites where the post-construction volumes or velocities of stormwater runoff are significantly different from conditions existing prior to the construction activity; (m) A listing of all flocculants or chemical stabilization products to be used at the site, including Material Safety Data Sheets (MSDS) and the dosage(s) to be used and the location(s) where these materials will be used; 12 (n) The most recent site topographic map (e.g.USGS quadrangle map) at an appropriate contour interval, clearly showing: (i) Sufficient detail to identify the location of the construction site; (ii) Existing topography and drainage patterns and features, existing structures proposed roads, utilities, ROWs, and waterbody(s); (iii) Drainage patterns and approximate slopes anticipated after major grading activities; (iv) The external and internal (if subdivided) property boundaries of the project; (v) Areas to be disturbed by excavation, grading, or other activities; (vi) Identification of sediment control measures, erosion control measures, planned stabilization measures, and other site management practices; (vii) Locations of all waters of the State within a 1 mile radius of the site (viii) Locations of wetlands and riparian zones; (ix) Locations of all points where stormwater leaves the property or after the last point of treatment; (x) Locations of all points of discharges to waters of the State; (o) A description of procedures for: (i) Sweeping or removal of sediment and other debris that has been tracked from the site or deposited from the site onto streets and other paved surfaces; (ii) Removal of sediment or other pollutants that have accumulated in or near any sediment control measures, stormwater conveyance channels, storm drain inlets, or water course conveyance within or immediately outside of the construction site; and (iii) Removal of accumulated sediment that has been trapped by sediment control measures at the site, in accordance with applicable maintenance requirements covered under this permit; and . (p) A description of the procedures for handling and disposing of wastes generated at the site, including, but not limited to, clearing and demolition debris, sediment removed from the site, construction and domestic waste, hazardous or toxic waste, and sanitary waste. 5.

Vegetation: Site vegetation currently consists primarily of open grass and trees. 1.5 Pre- and Post- Construction Site Estimates The following are estimates of the construction site. Total project area: 53 acres Construction site area to be disturbed: 23 acres 1.6 Receiving Waters Description of receiving waters: There is an unnamed tributary of Mountain Fork that runs along the southern boundary of the site. The perimeter lots will sheet flow through a minimum 25’ vegetative buffer to the stream, the interior lots will drain to roadway inlets which will discharge to the stream to the south at 2 locations: 34°52'42.26"N, 86°26'37.43"W and 34°52'42.43"N, 86°26'32.96"W. The northernmost lots will drain to roadway inlets which will discharge to a small onsite detention pond. The pond will discharge to the roadway ditch and flow south before entering the UT of Mountain Fork at 34°52'49.42"N, 86°26'45.84"W. Description of impaired waters or waters subject to TMDLs: This is a PRIORITY CONSTRUCTION SITE. It is located in the Flint River Watershed. 1.7 Potential Sources of Pollution Potential sources of sediment to stormwater runoff: It is anticipated that a potential source of pollution associated with construction work at the site would be sedimentation runoff from the site grading exercises. An erosion control plan has been developed to control the erosion and sedimentation runoff during construction. 1.8 Maps See appendices A and B for the USGS Location Map and construction drawings for the site. 4 Construction Best Management Practices Plan (CBMPP) Winchester Rd Subdivision - September 2019 SECTION 2: EROSION AND SEDIMENT CONTROL BMPS 2.1 Minimize disturbed area The entire site is about 53 acres in size.

In the event that construction stops for thirteen (13) days temporary stabilization shall be required. For mulching and seeding rates see section 2.4 and The Alabama Handbook for Erosion Control, Sediment Control and Storm water management on Construction Sites and Urban Areas, September 2014. 2.2 Phase Construction Activity The following sequence of construction will occur: Phase I: Clearing, Grading, Grubbing - BMPs: Silt fence, wattle ditch checks, temporary seeding, mulch, construction entrance/exit pad, rip-rap outlet protection, vegetative buffer, detention pond Phase II: Utility Installation, Asphalt, Curb & Gutter - BMPs: Silt fence, wattle ditch checks, temporary seeding, mulch, construction entrance/exit pad, rip-rap outlet protection, wattle inlet protection, vegetative buffer, detention ponds Phase III: Home Construction - BMPs: Silt fence, wattle ditch checks, wattle inlet protection, rip-rap outlet protection, permanent seeding, sod, vegetative buffer, detention ponds Phase IV: Final Stabilization - Permanent seeding, sod, rip-rap, vegetative buffer, rip-rap outlet protection, detention ponds 2.3 Control Stormwater flowing onto and through the project Storm water from off-site sources does not flow onto project area from off-site sources. Stormwater onsite will be treated by silt fence, wattles, wattle inlet protection, rip-rap, a vegetative buffer, and detention ponds. 2.4 Stabilize Soils Areas within the project site where construction activities have temporarily ceased for thirteen (13) days will be stabilized through the use of temporary mulching and seeding. The Contractor shall be responsible for controlling dust generation at the site through the use of water sprayed at intervals deemed necessary. Mulching shall be tacked. Permanent seeding shall follow The Alabama Handbook for Erosion Control, Sediment Control and Storm water management on Construction Sites and Urban Areas, September 2014 specifications. Temporary and permanent seeding shall use Bermuda grass at a rate of 10 pounds per acre during April 1st to July 1st. Any temporary or permanent seeding after July 1st will use tall fescue at a rate of 50 pounds per acre during September 1st to November 1st, Inspect seeding weekly until a stand is 5 Construction Best Management Practices Plan (CBMPP) Winchester Rd Subdivision - September 2019 established and thereafter at least monthly for stand survival and vigor. Also, inspect the site for erosion. Eroded areas should be addressed appropriately by filling and/or smoothing, and reapplication of lime, fertilizer, seed and mulch. A stand should be uniform and dense for best results. Stand conditions, particularly the coverage, will determine the extent of remedial actions such as seedbed preparation and reseeding. A qualified design professional should be consulted to advise on remedial actions. Consider drill seeding when doing a remedial planting. All sod should be kept moist until it is fully rooted. Mow to a height of 2" to 3" after sod is well-rooted, frequently in 2 to 3 weeks. Do not remove more than 1/3 of the leaf blade in any mowing. Permanent, fine turf areas require yearly fertilization. Fertilize warm-season grass in late spring to early summer; fertilize cool-season grass in early fall and late winter. Fertilize at rates recommended by a soil test. It is recommended to use 2 tons/acre of ground agricultural lime. This project is in North Alabama according to the Geographical Areas for Species Adaptation Figure in the above referenced guidance material. Reference Table PS-1 of The Alabama Handbook for Erosion Control, Sediment Control and Storm water management on Construction Sites and Urban Areas, September 2014 for commonly used plants for permanent cover with seeding rates and dates of planting. Use Straw and Seed mulch at a rate of two (2) tons/acre. Uniformly spread the mulch by hand or with a mulch blower at a rate which provides about 75% ground cover. When spreading straw mulch by hand, divide the area to be mulched into sections of approximately 1000 sq. ft. and place 70- 90 pounds of straw (1 1/2 to 2 bales) in each section to facilitate uniform distribution. Inspect all mulches periodically, and after rainstorms to check for rill erosion, dislocation, or failure. Where erosion is observed, apply additional mulch or if washout has occurred, repair the slope grade, reseed, and reinstall mulch. Continue inspections until vegetation is firmly established. Grade and loosen the soil to a smooth firm surface to enhance rooting of seedlings and reduce rill erosion. Break up large clods and loosen compacted, hard or crusted soil surfaces with a disk, ripper, chisel, harrow or other tillage equipment. Avoid preparing the seedbed under excessively wet conditions. Operate the equipment on the contour. For broadcast seeding and drilling, tillage, as a minimum, should adequately loosen the soil to a depth of at least 6", alleviate compaction, and smooth and firm the soil for the proper placement of seed. For no-till drilling, the soil surface does not need to be loosened unless the site has surface compaction. Incorporate lime and fertilizer to a depth of at least 6" with a disk or rotary tiller on slopes of up to 3:1. On steeper slopes, lime and fertilizer may be applied to the surface without incorporation. Lime and fertilizer may be applied through hydroseeding equipment; however, fertilizer should not be added to the seed mixture during hydroseeding. Lime may be added with the seed mixture. Final stabilization of disturbed areas must, at a minimum, be initiated immediately whenever any clearing, grading, excavating or other earth-disturbing activities have permanently ceased on any portion of the site. Temporary stabilization of disturbed areas must be initiated immediately whenever work toward project completion and final stabilization of any portion of the site has temporarily ceased on that portion of the site and will not resume for a period exceeding thirteen (13) calendar days. Permanent stabilization of disturbed areas must, at a minimum, be initiated immediately whenever any clearing, grading, excavating, or any other earth disturbing activities have permanently ceased on any portion of the site. 2.5 Stabilize Slopes All ditch slopes shall be mulched and seeded or sodded as necessary, and outlets will have rip- rap outlet protection. All mulched areas will be inspected periodically and after rainstorms for 6 Construction Best Management Practices Plan (CBMPP) Winchester Rd Subdivision - September 2019 erosion and damage to the mulch. It will be repaired promptly and restored to original condition. Inspections will continue until vegetation is well established. Sod shall be kept moist until fully rooted. Rip-rap will also be inspected after heavy rains, if erosion has occurred or rocks have been displaced, repairs will be made immediately. 2.6 Protect Storm Drain Inlets Drainage inlets are located in the curb and gutter of the roadway. These inlets will have wattle inlet protection in place for the duration of the project. Wattles will be inspected at least once a week or after each significant rain event. Should the wattle tear, decompose or become ineffective, it will be replaced promptly. Sediment will be removed with it reaches ½ the height of the barrier. 2.7 Establish Perimeter Controls and Sediment Barriers Silt fence is to be installed around the perimeter of the construction site, trapping sediment that is generated on-site. Silt fence shall be type "B", with materials and installation as detailed in (Appendix B). As a minimum, sediment that collects to a point 15 inches high or 1/2 the height of the silt fence shall be immediately removed, and spread over and blended-in with on-site soils or stockpiled with site spoil materials and disposed of in accordance with the Contractor's permits and local governing regulations. Silt fence should be inspected weekly and after each significant rain event. Silt fence should be replaced promptly if any collapse, tears, or decomposition occurs. See Appendix B for additional specific silt fence details. 2.8 Retain Sediment On-Site Sediment shall be retained on site with silt fence surrounding the outside of the construction area, wattle check dams in the ditches, a detention pond, and vegetative buffer. Use ALDOT Type "B" Silt Fence. Silt Fence and wattles will be inspected regularly, and sediment will be removed when it reaches ½ the height of the barrier. A detention area will be located on the northwest corner of the site, the drainage area is 8.66 acres and the storage capacity is 37,367 cf. A minimum 25-foot vegetative buffer will be maintained along the potential wetland area and stream bank on the southern boundary. See Appendix G for additional installation and maintenance details. 2.9 Establish Stabilized Construction Exits Stabilized construction access pads shall be installed at the construction entrance (see erosion control plans in Appendix B). They shall be maintained throughout construction to limit sediment from leaving the site. Remove large chunks of mud or caked soil from construction exit pad daily to minimize sediment buildup. Inspect stone pad and sediment disposal area weekly and after storm events or heavy use. Reshape pad as needed for drainage and runoff control. Top-dress with clean specified stone as needed to maintain effectiveness of the practice. Immediately remove mud or sediment tracked or washed onto public road. Repair any broken road pavement immediately. Remove unneeded exit pad materials from areas where permanent vegetation will be established. Immediately after the establishment of construction entrances/exits, all perimeter erosion devices and storm water management devices shall be installed prior to any other construction. 7 Construction Best Management Practices Plan (CBMPP) Winchester Rd Subdivision - September 2019 2.10 Removal of Sediment and Other Debris Deposited Off- Site Sediment and other debris that that has been tracked from the site or otherwise deposited from the site onto streets or other paved surfaces shall be immediately removed and replaced back on- site. Removal of sediment and debris shall be accomplished by means appropriate to the material and its condition - hand or mechanized shoveling, hand sweeping, mechanized weeping/vacuum, raking or a combination of the above, as necessary to restore all off-site surfaces to their pre-deposition or better condition. Removed sediment shall be returned to the site, stockpiled with site spoil materials and disposed of in accordance with the Contractor's earthwork permit and local governing regulations. Other non-sediment debris that is removed shall be returned to the site and placed in appropriate receptacles for disposal in accordance with the Contractor's permits and local governing regulations. 8 Construction Best Management Practices Plan (CBMPP) Winchester Rd Subdivision - September 2019 SECTION 3: GOOD HOUSEKEEPING (GROUNDS KEEPING) BMPS 3.1 Material Handling and Waste Management The Contractor shall be responsible for all construction waste and materials handling. The Contractor shall use reasonable care in the handling of fertilizers, pesticides, and other potential soil contaminants to prevent the site soils from becoming contaminated with such materials by spillage, runoff or other means. This includes but is not limited to the use of storage sheds, covered bays, drop cloths, spill trays and/or other containment vessels. In the event soils do become contaminated, the Contractor shall use means necessary to contain and minimize the contamination as well as to prevent the contamination from spreading. The Contractor shall remove all contaminated soils from the site using containers and vehicles suited for the purpose, and shall dispose of the contaminated materials by legal means off-site at a landfill or other facility legally permitted to accept such materials. The Contractor shall log any and all contamination incidents in the Daily Observation Log and report to the QCP immediately any contamination which cannot be readily contained and remediated. Hazardous materials will not be stored onsite. In the event they do occur, the CBMPP will be amended accordingly. The contractor shall not discard un-empty containers, and shall dispose of unused materials and empty material containers in accordance with manufacturers' recommendations as well as local, state and federal law. The Contractor shall deposit clearing and demolition debris, sediment to be removed from the site, and construction/domestic ln covered containers suited for the purpose. The Contractor shall promptly remove from the site and dispose all such materials by legal means at a landfill or other facility legally permitted to accept such materials. Sanitary waste shall be managed through the use of portable toilet systems. The Contractor will take measures to ensure that such systems are located away from storm water conveyances or outfalls, kept in proper working order and regularly serviced. Portable toilets shall be situated on level ground.

This practice applies on construction sites and other disturbed areas that can support vegetation and can be particularly effective on floodplains, next to wetlands, along stream banks and on steep, unstable slopes. Typical Components of the Practice  Preservation and Protection of Existing Vegetation  Site Preparation  Soil Amendments (lime and fertilizer)  Planting Desired Vegetation  Mulching Installation (Preservation) Prior to start of construction, buffer zones should be designed by a qualified design professional. Plans and specifications should be referred to by field personnel throughout the installation process. Preserve vegetation on designated areas shown in plan. In the absence of a plan, maintain a buffer of existing vegetation with a minimum width for shoreline or _________________ Installation and Maintenance Of Best Management Practices September 2014 197 stream bank protection of at least 35 feet. Local ordinances may require a wider buffer. Narrower buffer zones may be sufficient on steep slopes that are narrower than 35 feet. Installation (Plantings) Prior to start of construction, buffer zones should be designed by a qualified design professional. Plans and specifications should be referred to by field personnel throughout the installation process. Site Preparation Install planned measures such as silt fences and diversions before grading and seedbed preparation. In the absence of a plan and before grading and seedbed preparation, install other necessary measures which may include silt fences and diversions. Clear area of clods, rocks, etc. that would interfere with seedbed preparation; smooth the area before the soil amendments are applied and firm the soil after the soil amendments are applied. Soil Amendments (lime and fertilizer) Apply lime and fertilizer according to the plan or by soil test recommendations. In the absence of a plan or soil test recommendations, apply agricultural limestone at the rate of 2 tons per acre (90 lbs per 1000 ft2.) and 10-10-10 fertilizer at the rate of 1000 lbs per acre (25 lbs per 1000 ft2.). Apply ground agricultural limestone unless a soil test shows pH of 6.0 or greater. Incorporate amendments to a depth of 4” to 6” with a disk or chisel plow. Planting Desired Vegetation Plant desired vegetation according to the design plan. In the absence of a plan use installation guidelines for Permanent Seeding, Tree Planting on Disturbed Areas, Shrub, Vine and Groundcover Planting. Mulching Spread mulch according to guidelines in the Mulching practice. Common Problems Consult with qualified design professional if any of the following occur:  Soil compaction can prevent adequate plant growth. Compaction should be addressed during site preparation.  Design specifications for plants (variety, seeding/planting dates) and mulch cannot be met; substitutions may be required. Unapproved substitutions could lead to failure. Chapter 3 __________________________________________________________ 198 September 2014 Problems that require remedial actions:  Erosion, washout and poor plant establishment – repair eroded surface, reseed, reapply mulch and anchor.  Mulch is lost to wind or stormwater runoff – reapply mulch and anchor. Maintenance Replant trees, grass, shrubs or vines where needed to maintain adequate cover for erosion control. Maintain grass plantings with periodic applications of fertilizer and mowing. _________________ Installation and Maintenance Of Best Management Practices September 2014 199 Installation Instructions – Travel Lane Wattles Product Description: Constructed of a high visibility green polyester mesh, the Travel Lane Wattle is a sediment log filled with pine straw. Handles are attached to allow for easy lifting and placement. Purpose: Travel Lane Wattles (TLWs) are designed as a reusable sediment control device installed at worksite entrance and exit points or in travel lanes. Other applications include erosion management in slope control environments, stream protection or ditch checks. Quality Control: Travel Lane Wattles – Three Sizes TLW10 8” x 10’ TLW15 8” x 15’ TLW22 8” x 22’  High Visibility Green Polyester  Pine Straw Filled  Reusable Sediment Control Devise  Alternate uses – slope erosion control / stream protection  Designed for Flexibility  Easy Maintenance  Attached Handles for Easy Lifting Description: Travel Lane Wattles – This product is a sediment log of pine straw, wrapped with a high visibility polyester green mesh fabric. Attached handles allow for easy lifting and placement. It is designed as a reusable sediment control device at worksite entrance and exit points or in travel lanes. Other uses include control slope erosion, for stream protection or in ditch check applications. When used for slope erosion control, the weight of the device should be sufficient to hold in place when laid on contours. Another option is to stake it using an “X” pattern over the log. Designed to be flexible and easily maintained, the Travel Lane Wattle should be inspected at the end of each work day, particularly following rainfall events. Accumulated sediment should be removed and properly disposed. Longevity: The life of this product is determined at the point in which it is no longer effective or needed to do the job for which it was designed. Installation and Maintenance of Best Management Practice Check Dam (CD) Practice Description A check dam is a small barrier or dam constructed across a swale, drainage ditch or other area of concentrated flow for the purpose of reducing channel erosion. Channel erosion is reduced because check dams flatten the gradient of the flow channel and slow the velocity of channel flow. Most check dams are constructed of rock, but hay bales, logs and other materials may be acceptable. Contrary to popular opinion, most check dams trap an insignificant volume of sediment. This practice applies in small open channels and drainageways, including temporary and permanent swales. It is not to be used in a live stream. Situations of use include areas in need of protection during establishment of grass and areas that cannot receive a temporary or permanent non-erodible lining for an extended period of time. Typical Components of the Practice  Site Preparation  Materials Installation  Erosion and Sediment Control  Construction Verification March 2009 91 Chapter 3 Construction Prior to start of construction a qualified design professional should determine the location, elevation and size of the structure to optimize flattening of channel grade. Usually, check dam dimensions are taken from a standard drawing. Check dams are typically constructed using materials included in a contract. Note: Construction with rock is the only check dam material covered in this edition of the handbook. Site Preparation Determine location of any underground utilities. Locate and mark the site for each check dam in strategic locations (to avoid utilities and optimize effectiveness of each structure in flattening channel grade). Remove debris and other unsuitable material which would interfere with proper placement of the check dam materials. Excavate a shallow keyway (12”-24” deep and at least 12” wide) across the channel and into each abutment for each check dam. Materials Installation As specified, install a non-woven geotextile fabric in the keyway in sandy or silty soils. This may not be required in clayey soils. Construct the dam with a minimum 2:1 side slopes over the keyway and securely embed the dam into the channel banks. Position rock to form a parabolic top, perpendicular to channel flow, with the center portion at the elevation shown in the design so that the flow goes over the structure and not around the structure. Erosion and Sediment Control Install vegetation (temporary or permanent seeding) or mulching to stabilize other areas disturbed during the construction activities. Construction Verification Check finished size, grade and shape for compliance with standard drawings and materials list (check for compliance with specifications if included in contract specifications). 92 March 2009 Installation and Maintenance of Best Management Practice Common Problems Consult with a qualified design professional if any of the following occur:  Variations in topography on site indicate check dam will not function as intended. Change in plan will be needed.  Materials specified in the plan are not available. Maintenance Inspect the check dam for rock displacement and abutments for erosion around the ends of the dam after each significant rainfall event. If the rock appears too small, add additional stone and use a larger size. Inspect the channel after each significant rainfall event. If channel erosion exceeds expectations, consult with the design professional and consider adding another check dam to reduce channel flow grade. Sediment should be removed if it reaches a depth of ½ the original dam height. If the area behind the dam fills with sediment there is a greater likelihood that water will flow around the end of the check dam and cause the practice to fail. Check dams may be removed when their useful life has been completed. The area where check dams are removed should be seeded and mulched immediately unless a different treatment is prescribed. In some instances check dams should be left as a permanent measure to support channel stability.
