Hazardous materials: oils, gasoline, paint, and any hazardous <br />substance must be properly stored, including secondary <br />containment, to prevent spills, leaks or other discharge. <br />Restricted access to storage areas must be provided to prevent <br />vandalism. Storage and disposal must be in compliance with <br />MPCA regulations. <br />3. External washing of trucks or other construction vehicles is not <br />allowed on site.

MnDOT Type 1 mulch shall be applied <br />at 2 tons/ac and disc anchored in areas not covered by sod <br />or erosion blanket. <br />3. Fertilizer shall be MnDOT Type 1 10-10-20 and applied at 200 <br />lbs/ac. Disc fertilizer into top 3" of soil. Specification <br />reference is MnDOT 2575. <br />4. Dormant seed mix shall be used after November 1 or when <br />temperatures do not exceed 40' F, using some rates specified <br />above. No seed shall be placed on snow or ice greater than <br />2" in depth. <br />5. Any seeded areas that do not become established with <br />vegetation shall be reseeded at Contractor's expense. <br />6.

Specifications applicable for this project: Current standard <br />specifications for the City of Orono; the latest Minnesota Department <br />of Transportation Specifications for Highway Construction; and all <br />NPDES requirements except where modified by these documents. <br />2. OSHA requirements shall be followed for all work on this project. <br />3. The Contractor shall notify "Gopher State One Call" 48 hours prior to <br />any excavation (1-800-252-1166.) <br />4. The Grading Contractor shall verify all locations and elevations of <br />underground utilities with utility companies prior to any construction, <br />and immediately notify the Engineer of any conflicts. <br />5. Final Plat shall govern for easements and lot dimensions. <br />6. Any erosion control items necessary to protect adjacent properties shall <br />be constructed prior to the start of excavation or grading work. <br />7. Erosion control maintenance shall be performed by the Grading <br />Contractor, and removed -as per the, Contract Documents or as <br />directed by the Owner, followed by all necessary restoration of <br />disturbed area. <br />8. The Grading contractor shall provide positive drainage on the site at all <br />times. Grading tolerances shall be 0.10' for hard surface areas. <br />Grading tolerances for the remainder of the site shall be 0.25'. <br />9. The Grading Contractor shall keep public streets, parking lots, and <br />travel ways clear of soil and debris.

Silt fence shall be inslalled or restored prior to any construction- Silt fence <br />shall be located as shown to intercept runoff. The area located beyond the' <br />perimeter silt fence shall not be disturbed during construction. <br />2. Rock Construction Entrance shall be installed prior to grading operations. <br />3. All storm sewer inlets shall have inlet protection inserts installed. <br />Inserts shall be "Road rain -Top Slab" or "Road Drain -Curb & Gutter" <br />inlet protection devices as manufactured by WIMCO (or approved equal) <br />and installed per manufacture's recommendations. <br />4. All erosion control installations shall remain in place and be maintained in <br />good condition by the contractor- until the site has been re -vegetated, at <br />which time it shall be removed by the contractor. For proposed paved surface <br />areas, the contractor may remove necessary silt fencing to construct roadway, <br />while maintaining adequate erosion control in adjacent areas. <br />5. Sufficient topsoil shall be stockpiled to allow for the replacement of 4" topsoil <br />for disturbed areas to be re -vegetated. <br />6. The contractor shall schedule site grading, utility installation and site <br />construction so that the general site can be mulched and sodded or <br />re -seeded as soon as possible soon after disturbance. Areas that will not be <br />subject to construction traffic shall be seed and mulched or sodded within 72 <br />hours of final grading. <br />EROSION CONTROL MAINTENANCE SCHEDULE <br />1. Erosion control measures shall be inspected by the contractor's representative <br />and maintained by the contractor every Friday and within 24 hours after any <br />rainfall event larger than 1/2" until the project is completed. Maintenance <br />requirements are as follows: silt fence - 1/3 height of fence or damaged, <br />remove sediment and/or repair fence within 24 hours; rock entrance - <br />refresh as necessary to conform to detail; inlet protection inserts - remove <br />sediment after each rain event, clean or replace filter when clogged; surface <br />water - drain and stabilize, within 72 hours of discovery; street sweeping - <br />remove all sediment tracked onto paved surfaces within 24 hours or as <br />directed by City Eng'neer. <br />2. Replacement - Fabr'c shall be replaced promptly when it decomposes or <br />becomes ineffective before the barrier is no longer necessary. <br />3. Any sediment remaining in place after silt fence is no longer required shall be <br />dressed to conformw` h the existing grade, prepared, and seeded with <br />appropriate seed mix, s directed by the engineer. <br />4.
