The Cemetery Road and Washington Street improvements are located in the Village of Gurnee,Lake County, Illinois. The improvements along Cemetery Road begin 151 feet south ofWashington Street and extend 5,330 feet north to the intersection of Tri-State Parkway. Theimprovements of Washington Street begin 2,120.80 feet west of Cemetery Road and extend1,460.20 feet east of Cemetery Road for a total length of 3,580 feet. The improvements alongTri-State Parkway begin 972 feet east of Cemetery Road and extend 500 feet south of IL Rte 132(Grand Avenue) for a total length of 1,358 feet. The total project length is 10,268 feet or 1.95miles. The project area is located in Section 16 & 21, Township 45N and Range 11 E. Nostormwater detention is currently provided, or is proposed with these improvements.

Description of Improvement

The project area involves widening of approximately 5,330 feet of Cemetery Road, widening ofapproximately 3580 feet of Washington Street, and resurfacing of approximately 1358 feet of Tri-State Parkway, and intersection improvements at the intersection of Cemetery Road andWashington Street and the intersection of Illinois Route 132 (Grand Avenue) and Tri-StateParkway in the Village of Gurnee, Lake County.

Proposed work includes roadway demolition, earth excavation, bituminous pavement widening,combination concrete curb and gutter, enclosed drainage system, pavement marking, signing,utility installation, traffic signal installation, landscape restoration and all incidental worknecessary to complete the improvements as shown on the plans and as described herein. A newtraffic signal will be installed at the Cemetery Road and Washington Street intersection and willbe under Lake County Division of Transportation jurisdiction.

Cemetery Road will be widened from a 20 foot edge-to-edge bituminous concrete pavement with3-foot aggregate shoulders to a 31-foot back-to-back curb and gutter. A 10-foot joint use bicyclepath will be constructed on the west side of the roadway.

Currently Washington Street west of Cemetery Road consists of a 34-foot edge-to-edgebituminous concrete pavement with 3-foot bituminous and 6-foot aggregate shoulders. It consistsof one traffic lane in each direction and painted median or turning lane. Washington Street east ofCemetery Road consists of a 24-foot edge-to-edge bituminous concrete pavement withbituminous and aggregate shoulders. Washington Street will be re-constructed to a 65-foot back-to-back with two 12-foot through lanes in each direction and one 12-foot painted median with curband gutter type B-6.24. A 10-foot joint use bicycle path will be constructed on the north side ofWashington Street.

Tri-State Parkway, consisting of B-6.12 curb and gutter, is proposed to be resurfaced. It will bewidened at the intersection of Tri-State Parkway and Grand Avenue (Illinois Route 132) toaccommodate additional lanes.

SECTION 2: CONTROLS

Approved State or Local Plans

The management practices, controls and other provisions contained in this storm water pollutionprevention plan are at least as protective as the requirements contained in the IllinoisEnvironmental Protection IEPA’s Illinois Urban Manual, 2002. Requirements specified in plans orpermits for this project approved by local officials that are applicable to protecting surface waterresources are, upon submittal of a NOI to be authorized to discharge under ILR10 permit,incorporated by reference and are enforceable under the ILR 10 permit even if they are notspecifically included in the storm water pollution prevention plan. This provision does not apply toprovisions of master plans, comprehensive plans, non-enforceable guidelines or technicalguidance documents that are not identified in a specific plan or permit that is issued for thisproject.

The soil erosion and sediment control measures for this site should meet the requirements of thefollowing agencies:

Village of GurneeLake County Stormwater Management CommissionIllinois Environmental Protection AgencyU.S. Army Corps of Engineers

Erosion and Sediment Controls

The appropriate soil erosion and sediment controls shall be implemented onsite and shall bemodified to reflect the current phase of construction. All damaged or defective temporarysediment and erosion control measures must be repaired or replaced as soon as possible tomaintain NPDES compliance.

Unless otherwise indicated, all vegetative and structural erosion and sediment control practicesshall be installed according to the Standard Practice. The contractor shall be responsible for theinstallation of any additional erosion and sediment control measures necessary to prevent erosionand sedimentation as determined by the engineer, owner, or permitting authority.

1. Stabilization PracticesAreas that will not be paved or covered with non-erosive material shall be stabilized asindicated on the erosion control plan using procedures in substantial conformance withthe Illinois Urban Manual. See Soil Erosion Control Plan, Notes and Details prepared byGewalt Hamilton Associates, Inc. for site specific erosion and sediment control measures.Except as provided in paragraphs (a) and (b) below, stabilization measures shall beinitiated as soon as practicable in portions of the site where construction activities havetemporarily or permanently ceased, but in no case more than 7 days after theconstruction activity in that portion of the site has temporarily or permanently ceased asfollows:

a. Where the initiation of stabilization measures by the 7th day after constructionactivity temporarily or permanently ceases on a portion of the site is precluded bysnow cover, stabilization measures shall be initiated as soon as practicable.

b. Where construction activity will resume on a portion of the site within 14 days fromwhen activities ceased (i.e. the total time period that construction activity istemporarily ceased is less than 14 days) then stabilization measures do not have tobe initiated on that portion of the site by the 7th day after construction activitytemporarily ceased.

2. Structural PracticesStructural practices will be utilized to divert flows from exposed soils, store flows orotherwise limit runoff and the discharge of pollutants from exposed areas of the site.Such practices may include drainage swales, earth dikes, sediment traps, check dams,subsurface drains, pipe slope drains, level spreaders, storm drain inlet protection, rockoutlet protection, reinforced soil retaining systems, gabions and temporary or permanentsediment basins, storm water detention basins, concrete washout areas, silt fence,rirprap, coir logs and other measures. Structural practices should be placed on uplandsoils to the degree practicable. Installation of these structural practices should followStandard Practice as outlined in the Illinois Urban Manual.

Implementation Schedule

Perimeter controls of the site and stabilized construction entrance shall be installed prior todemolition, clearing and grubbing. Perimeter controls shall be actively maintained until finalstabilization of those portions of the site upward of the perimeter control. Existing storm sewerinlets that will function during the construction process should have the sediment controlmeasures installed as indicated prior to land - disturbing activities, including demolition and siteclearing. In addition, sediment control measures shall be installed in newly constructed inletsimmediately after their installation is complete. Erosion control blanket may be used to stabilizethe construction areas where the final grade has been reached but cannot be permanentlystabilized due to planting season restrictions. Permanent controls, such as riprap, shall beinstalled at each storm sewer outfall structures prior to any storm water discharge. Temporaryperimeter controls shall only be removed after final stabilization of those portions of the siteupward of the perimeter control.

Temporary drop in Catch-All sediment bags will be utilized on all inlets to prevent infiltration ofsediment-laden ground water into existing and proposed structures. Catch-All bags shall remainin place until placement of base course in paved areas or until vegetation has taken hold. Careshall be taken when removing sediment bags to avoid entry of sediment into the storm sewer.

Storm Water Management

Provided below is a description of measures that will be installed during the construction processto control pollutants in storm water discharges that will occur after construction operations havebeen completed. The installation of these devices may be subject to Section 404 of the CleanWater Act.

(i) Such practices may include: storm water detention structures (including wet ponds);storm water retention structures; flow attenuation by use of open vegetated swales andnatural depressions; infiltration of runoff on site; and sequential systems (which combineseveral practices). The practices selected for implementation were determined on thebasis of the technical guidance in Section 10-300 (Design Considerations) in Chapter 10(Erosion and Sedimentation Control) of the Illinois Department of TransportationDrainage Manual. If practices other than those discussed in Section 10-300 are selectedfor implementation or if practices are applied to situations different from those covered inSection 10-300, the technical basis for such decisions will be explained below.

(ii) Velocity dissipation devices will be placed at discharge locations and along the length ofany outfall channel as necessary to provide a non-erosive velocity flow from the structureto a water course so that the natural physical and biological characteristics and functionsare maintained and protected (e.g., maintenance of hydrologic conditions, such as thehydroperiod and hydrodynamics present prior to the initiation of construction activities).

(iii) Storm sewer improvements are specifically described within the Drainage Report, thoughoutfalls will follow IDOT standards. One specific structure, where existing stormwater is aproblem issue, is designated to be a CDS stormwater cleaning unit.

Off-Site Vehicle Tracking

Roads shall be swept as needed to reduce excess sediment, dirt or stone tracked from the constructionarea. Accumulated sediment and stone shall be removed from the construction area as needed. Waterrunoff from vehicle washing shall be contained in an area that does not discharge directly into a Waters ofthe State and this washing area shall be periodically inspected and repaired as necessary throughout thelife of the project. Vehicles hauling erodible material to and from the construction site should be coveredwith a tarp.

Dust Control

As requested a water truck will be used to limit the amount of dust leaving the site. The following list ofcontrol measures may also be implemented on-site to limit the generation of dust as needed:

Sprinkling/irrigation Vegetative cover Mulch Spray-on soil treatments Tillage Stone

De-Watering Operations

During de-watering/pumping operations, only uncontaminated water should be allowed to discharge toprotected natural areas, Waters of the State or to a storm sewer system. Inlet hoses should be placed ina stabilized sump pit or floated at the surface of the water with a screen in order to limit the amount ofsediment intake. Pumping operations may be discharged to a stabilized area that consists of an energydissipating device (i.e. stone) on a stabilized surface, sediment filter bag on a stabilized surface or asediment removal channel. Adequate erosion controls should be used during de-watering operations asnecessary. Stabilized conveyance channels should be installed to direct water to the desired location asapplicable. Additional erosion control measures may be installed at the outlet area at the discretion of thePrimary Contact or Engineer.

SECTION 3: GOOD HOUSEKEEPING BMPS

Waste Management

No solid materials, including building materials, shall be discharged to Waters of the State, except asauthorized by a Section 404 permit. All waste materials shall be collected and stored in approvedreceptacles. No wastes shall be placed in any location other than in the approved containers appropriatefor the materials being discarded. There shall be no liquid wastes deposited into dumpsters or othercontainers which may leak. Receptacles with deficiencies shall be replaced as soon as possible and theappropriate clean-up procedure shall take place, if necessary. Construction waste material is not to beburied on site. Waste disposal should comply with all local, State and Federal regulations. The provisionsof this plan shall ensure and demonstrate compliance with applicable State and/or local waste disposal,sanitary sewer or septic system regulations.

Hazardous material shall not be stored on site. Any hazardous waste should be disposed of in themanner specified by local or State regulation or by the manufacturer.

Concrete Waste Management

Concrete waste or washout should not be allowed in the street or allowed to reach a storm waterdrainage system or watercourse. A sign shall be posted at each location to identify the washout.Concrete washout areas should be located a reasonable distance from a storm water drainage inlet orwatercourse. Concrete washout areas shall be located at least 10 feet behind the curb, if the washoutarea is adjacent to a paved road. A stabilized entrance as detailed on the erosion control shall beinstalled at each washout area.

The washout areas shall be of sufficient volume to completely contain all liquid and concrete wastematerials including enough capacity for anticipated levels of rainwater. The dried concrete waste materialshall be picked up and disposed of properly when 75% of the capacity is reached. Hardened concretecan be properly recycled and reused on-site or hauled off-site to an appropriate facility.

Concrete Cutting

Concrete waste management should be implemented to contain and dispose of saw-cutting slurries.Concrete cutting should not take place during or immediately after a rainfall event. Waste generated fromconcrete cutting should be cleaned up and disposed into the concrete washout facility described above.

Vehicle Storage and Maintenance

When not in use, vehicles utilized in the development operations of the site shall be stored in adesignated upland area away from any natural or created watercourse, pond, drainage-way orstorm drain. Whenever possible, vehicle maintenance, fueling, and washing will occur off-site. Ifallowed on-site, vehicle maintenance (including both routine maintenance as well as on-siterepairs) shall be made within the designated area to prevent the migration of mechanical fluids(oil, antifreeze, etc.) into watercourses, wetlands or storm drains. Drip pans or absorbent padsshall be used for all vehicle and equipment maintenance activities that involve grease, oil,solvents or other vehicle fluids. Construction vehicles shall be inspected frequently to identify anyleaks. Leaks shall be repaired immediately or the vehicle should be removed from the site.Dispose of all used oil, antifreeze, solvents and other automotive-related chemicals according tomanufacturer MSDS instructions. Contractors shall immediately report spills to the PrimaryContact.

Material Storage

Materials and or contaminants shall be stored in a manner that minimizes the potential todischarge into storm drains or watercourses. An on-site area shall be designated for materialdelivery and storage. All materials kept on-site shall be stored in their original containers withlegible labels, and if possible, under a roof or other enclosure. Labels should be replaced ifdamaged or difficult to read. Bermed-off storage areas are an acceptable control measure to

prevent contamination of storm water. MSD sheets shall be available for referencing cleanupprocedures. Any release of chemicals/contaminants shall be immediately cleaned up anddisposed of properly. Contractors shall immediately report all spills to the Primary Contact, whoshall notify the appropriate agencies, if needed.

To reduce the risks associated with hazardous materials on-site, hazardous products shall bekept in original containers unless they are not re-sealable. The original labels and MSD datashall be retained on-site at all times. Hazardous materials and all other materials on-site shall bestored in accordance with manufacturer’s MSDS specifications. When disposing of hazardousmaterials, follow manufacturers’ or local and State recommended methods on Local, State andFederal regulations.

Sanitary Facilities

To the extent practicable, sanitary facilities shall be located at a minimum 8 feet behind the curband gutter of the internal roads and be located in an area that does not drain to any protectednatural area, Waters of the State or storm water structures. Sanitary facilities shall be anchoredto the ground to prevent tipping over. Sanitary facilities located on impervious surfaces shall beplaced on top of a secondary containment device, or be surrounded by a control device (i.e.gravel-bag berm).

Spill Preventions

Discharges of hazardous substances or oil caused by a spill are not authorized by the ILR10permit. If a spill occurs, notify the Primary Contact immediately. The construction site shall havethe capacity to control, contain and remove spills if they occur. Spills shall be cleaned upimmediately in accordance with MSD sheets and shall not be buried on-site or washed into stormsewer drainage inlets, drainageways or Waters of the State.

Spills in excess of federal Reportable Quantities (as established under 40 CFR Parts 110, 117 or302) shall be reported to the National Response Center by calling (800) 424-8802. MSDS ofteninclude information on federal Reportable Quantities for materials. Spills of toxic or hazardousmaterials shall be reported to the appropriate State or local government IEPA, regardless of size.When cleaning up a spill, the area shall be kept well ventilated and appropriate personalprotective equipment shall be used to minimize injury from contact with a hazardous substance.

Allowable Non-Storm Water Discharge Management

Except for flows from fire fighting activities, sources of non-storm water that may be combined withstorm water discharges associated with the activity addressed in this SWPPP are as follows:

Water main flushing Fire hydrant flushing Watering for Dust Control Irrigation drainage for vegetative growth for seeding, etc. Uncontaminated groundwater

The pollution prevention measures described below will be implemented for non-storm watercomponents of the discharge:

The fire hydrant and water main should not be flushed directly on the exposed area or subgradeof the pavement. Hoses should be used to direct the flow onto a stabilized area.

Erosion due to irrigation of seeding shall be minimized.

SECTION 4: INSPECTIONS & MAINTENANCE

Inspections

Qualified personnel (provided by the contractor) shall inspect disturbed areas of the construction site thathave not been finally stabilized, structural control measures, and locations where vehicles enter or exitthe site. Such inspections shall be conducted at least once every seven (7) calendar days and within 24hours of the end of a storm that is 0.5 inches or greater or equivalent snowfall.

Disturbed areas and areas used for storage of materials that are exposed to precipitation shall beinspected for evidence of, or the potential for, pollutants entering the drainage system. Erosionand sediment control measures identified in the plan shall be observed to ensure that they areoperating correctly. Where discharge locations or points are accessible, they shall be inspectedto ascertain whether erosion control measures are effective in preventing significant impacts toreceiving waters. Locations where vehicles enter or exit the site shall be inspected for evidenceof off site sediment tracking.

Based on the results of the inspection, necessary pollution prevention measures identified in thestorm water pollution prevention plan shall be undertaken as soon as practicable after suchinspection. Such modifications shall provide for timely implementation of any changes to the planwithin 7 calendar days following the inspection.

A report summarizing the scope of the inspection, name(s) and qualifications of personnel makingthe inspection, the date(s) of the inspection, major observations relating to the implementation ofthis storm water pollution prevention plan, and actions taken in accordance with the NPDESpermit shall be made and retained (for at least three (3) years from the date of final stabilizationor permit coverage is terminated) as part of this SWPPP. The report shall be signed inaccordance with Part VI. G (Signatory Requirements) of the ILR10 NPDES Permit.

The contractor shall notify the appropriate Agency Field Operations Section office by email atepa.swnoncomp@illinois.gov, telephone or fax within 24 hours of any incidence ofnoncompliance for any violation of the storm water pollution prevention plan observed during anyinspection conducted, or for violations of any condition of this permit.

If any violation of the provisions of this plan is identified during the conduct of the constructionwork covered by this plan, the Resident Engineer or Resident Technician shall complete and filean “Incidence of Noncompliance” (ION) per the requirements of the NPDES ILR10 GeneralConstruction Permit. Submission shall be on forms provided by the IEPA and include specificinformation on the cause of noncompliance, actions which were taken to prevent any furthercauses of noncompliance, and a statement detailing any environmental impact, which may haveresulted from the noncompliance. All reports of noncompliance shall be signed by a responsibleauthority in accordance with Part VI. G (Signatory Requirements) of the ILR10 NPDES GeneralConstruction Permit.

The report of noncompliance shall be mailed to the following address:

Illinois Environmental Protection AgencyDivision of Water Pollution ControlCompliance Assurance Section1021 North Grand Avenue EastPost Office Box 19276Springfield, Illinois 62794-9276

Maintenance of Controls

The following is a description of procedures that should be used to maintain, in good and effectiveconditions, vegetation, erosion and sediment control measures and other protective measures identifiedin this SWPPP and Standard Specifications. For additional information, see the Erosion and SedimentControl Plan and Construction Details.

Concrete washout areas: Existing facilities should be cleaned out, or new facilities should beconstructed and operational once the existing washout is 75% full. Washouts should be inspectedfrequently to ensure that plastic linings are intact and sidewalls have not been damaged byconstruction activities. When the washout area is adjacent to a paved road, the paved road shouldbe inspected for accumulated concrete waste. Any accumulated concrete waste on the road, curb,or gutter should be removed and properly disposed.

Erosion Control Blanket: The blanket and staples should be inspected frequently and shall beinstalled to Illinois Urban Manual Drawing Number IL-530, unless otherwise instructed by themanufacturer. Erosion occurring underneath the blanket should be back filled and seeded with theappropriate seed mix. Additional BMP’s may need to be installed to reduce erosion under theblanket.

Silt Filter Fence: Silt fences should be inspected regularly for undercutting where the fence meetsthe ground, overtopping, and tears along the length of the fence. Deficiencies should be repairedimmediately. Remove accumulated sediments from the fence base when the sediment reaches one-half the fence height. During final stabilization, properly dispose of any sediment that hasaccumulated on the silt fence. Instances when areas of silt fence continually fail, replace withanother BMP as seen fit. See Illinois Urban Manual Drawing Number IL-620.

Inlet Features: Inlet filters should be inspected for proper filtering. Remove sediment from the filterbags when 50% of the storage volume has been filled, unless otherwise instructed by themanufacturer. Remove trash and debris during inspections. Accumulated material in the filtersshould be disposed of properly. Do not puncture holes in filters if ponding occurs.

Correction Action Log

A corrective action log is located in Appendix F.

SECTION 5: RECORDKEEPING

Public Posting

The following notices shall be posted until the date of final site stabilization. A copy of the Notice of Intent shall be posted at the construction site in a prominent place for

public viewing. Notice to drivers of equipment and vehicles, instructing them to stop, check and clean tires of

debris and mud before driving onto traffic lanes. In an easily visible location on-site, post a notice of waste disposal procedures. Notice of hazardous material handling and emergency procedures shall be posted with the NOI

on-site. Keep copies of Material Safety Data Sheets at a location on-site that is known to allpersonnel.

Keep a copy of each signed certification at the construction site or at Contractor’s office.

Recordkeeping

The owner shall retain copies of the SWPPP and all reports and notices required by the ILR10permit, and records of all data used to complete the Notice of Intent to be covered by the ILR10permit, for a period of at least three years from the date that the permit coverage expires or isterminated unless extended by request of the IEPA. In addition, the contractor shall retain a copyof this SWPPP required by the ILR10 permit at the construction site from the date of projectinitiation to the date of final stabilization.

Log of Changes to the SWPPP

The owner shall amend the SWPPP whenever there is a change in design, construction,operation, or maintenance, which has a significant effect on the potential for discharge ofpollutants to Waters of the State and which has not otherwise been addressed in the SWPPP or ifthe SWPPP proves to be ineffective in eliminating or significantly minimizing pollutants, or inotherwise achieving the general objectives of controlling pollutants in storm water dischargesassociated with construction site activity. In addition, the SWPPP shall be amended to identifyany new contractor and/or subcontractor that will implement a measure of the SWPPP.Amendments to the SWPPP may be reviewed by the IEPA.

SECTION 6: FINAL STABILIZATION

Permanent stabilization has occurred when all soil disturbing activities at the site have been completed,and a uniform perennial vegetative cover with a density of 70% of the cover for unpaved areas and areasnot covered by permanent structures has been established or equivalent stabilization measures (such asthe use of riprap, gabions or geotextiles) have been employed.

When the site has been finally stabilized and all storm water discharges from construction sites that areauthorized by the ILR10 Permit are eliminated, the permittee of the facility must submit a completedNotice of Termination that is signed in accordance with Part VI.G (Signatory Requirements) of the permit.

Elimination of storm water discharges associated with industrial activity means that all disturbed soils atthe identified facility have been finally stabilized and temporary erosion and sediment control measureshave been removed or will be removed at an appropriate time, or that all storm water dischargesassociated with construction activities from the identified site that are authorized by a NPDES generalpermit have otherwise been eliminated.
