GRANDVIEW <br />STORM WATER POLLUTION <br />PREVENTION <br />[ S WPPPI <br />PLAN <br />City of Lino Lakes, Minnesota <br />GENERAL EROSION AND SEDIMENT CONTROL <br />INSPECTIONS AND MAINTENANCE <br />1. The Permtttee(s) (either the owner or operator) must routinely inspect the <br />construction site once every seven (7) days during Dative construction and within <br />24 hours after a rainfall event greater than 0.5 Inches in 24 hours <br />2. At inspections and maintenance conducted during construction must be recorded in <br />writing and these records must be retained with the SWPPP In ocoordonce with <br />RECORD DETENTION. Records of each Inspection and mdntenonce activity shag <br />Include aha8 include <br />a. Date and fine Inspections <br />b. Noma of persm(s) conducting inspection; <br />c Findings of Inspection, Including recommendations for corrective action; <br />d. Corrective actions taken (Including dotes, times. and party compietng <br />maintenance activities); <br />e. Date and amount of rainfall events greater than 1/2 inch (0.5 inches) <br />in 24 had; and <br />L Documentation of changes mode to the SIYPPP. <br />3 When ports of the constructon efts how undergone final etabnizatbn, but work <br />remains on other parts of the site, inspections of the stob0osd aim may be <br />reduced to once per month. When work has been suspended due to froze, ground <br />conditions, the required Inspections and maintenance must take place as soon ors <br />runoff occurs at the efts or prier to resuming construction. whichever comes first. <br />4. M erosion prevention and sediment control BLIP. most be inspected to ensure <br />integrity and effectiveness. M nonfunctional BAPS must be repaired, replaced, or <br />supplemented with functional BMPs The Permltee(s) must investigate and comply <br />with the following inspection and maintenance requirements <br />e M silt fences must be repaired replaced, or supplemented when they become <br />nonfanetiond (develop tears, detach from posts. post become dislodged from <br />ground, etc) or the sediment noshes 1/3 of the height of the fence. These <br />repairs must be mode .ithn 24 hours of discovery, or as man 0s the field <br />conditions agma proem <br />b. Temporary and pennmsnt sedimentation ponds must be droned and the sediment <br />removed when the depth of the sediment collected In the basin reaches 1/2 the <br />storage volume. Drainage and removal must be completed widen 72 hours of <br />discovery or as soon m field conditions allow access. <br />e Surface waters, Including drainage ditches and conveyance systems, must be <br />repeated for evidence of sediment being deposited by erosion. The PennItete(s) <br />must remove all deltas and sediment deposited in sumom waters.

The removal and stabilization must <br />take place within sewn (7) days of discovery unless precluded by legal, regulatory, <br />or physical constraint. The Permitee Mae use all reasonable efforts to <br />obtain access If precluded, removal and stabilization must tats place within sever <br />.11 moot, regional states andrfedwl authorities and�recea,g any responsible applicable permits, <br />prier to conducting any work <br />d Construction site vehicle eat locations must be Inspected far evidence o8 -she - <br />sediment tracking onto paved surfaces Tracked Indolent must be removed eon <br />an off-site paved enlaces, within 24 hours of discovery, or R applicable, within a <br />shorter time <br />s The Permittee(s) are responsible for operation and maintenance of temporary <br />and permanent water quality management RMPS as well as dl erosion prevention <br />ond sediment control BMPS for the duration of the conshuctkan work at the site <br />The Penntttee(e) an respectable until another Pennttee has assumed contra over <br />areas of the site that hove not been finally stabilized or the site has undergone <br />fad stab6sation, and a Notice of Termination has been submitted to the MPCA <br />(see TERMINATION C COVERAGE). <br />f. if sediment escapes is construction sits off-site accumulations must be removed <br />In o manner and at a frequency sufficient to minimize off-site impact. (e.g., <br />fugitive sediment in streets could be washed Into •norm sewers by the next rain <br />and /or pose a safety hazard to users of public farads). <br />5. M 'filtration areas must be inspected to ensure that no sediment from ongoing <br />construction activities is reaching the infiltration area and these areas are <br />protected from compaction due to construction equipment driving Dross the <br />Infiltration area <br />POLLUTION PREVENTION MANAGEMENT MEASURES <br />The Pormltee(s) Mae implement the following pollution prevention management <br />measures an the site <br />I. Solid Waste Collected sediment, asphalt and concrete millings, Booting debris, <br />paper, plastic, fabric, construction and demolition deb. and other wastes oust be <br />deposed of properly and must comply with MPCA disposal requirements <br />2. Hazardous Materials OE, gasoline, point and any hazardous substances moat be <br />property stared, including •eeandary containment to prevent spies leaks or other <br />discharge Restricted access to storag. areas must be provided to prevent <br />vandalism. Storage and disposal of hmordo o waste nest be in compliance with <br />MPG* regulations. <br />3 External washing of trues and other construction vehicle must be limited to 0 <br />defined area of the site Runoff must be contained and waste property deposed <br />of. No ongne degreasing is allowed on site <br />DE-WATERING AND BASIN DRAINING <br />1. Dewotertng or basin draining (e.g., pumped discharges. trench/ditch cuts for <br />drainage) related to the conatructl= actl*ty that may have turbid or sediment <br />laden discharge water must be discharged to a temporary or permanent <br />sedimentation book, on the project site whenever possible. If the water carrot be <br />discharged to sedimentation bas, prior to entering the surtoa water, it must <br />treated with the appropriate BMP, such that the discharge dos not dwasely <br />affect the receiving water or downstream landowners. The Pem tttee(s) rust <br />ensure that discharge points ore adequately protected from erosion and sixr. <br />T. discharge must be dispersed over noturd rock riprap, sand bogs plastic <br />sheeting or other °scented energy dsngotion measure.. Adequate sedimentation <br />control measures are required for discharge water that contains ausponded solids <br />2. M water from dewaterng or basin draining activities must be discharged in a <br />manner that does not sous nuisance conditions. erosion in receiving channels or <br />on ...lope properties r inundation in wetland. causing slgnifko t adverse <br />Impact to the wetland <br />AMENDMENTS TO SWPPP <br />The Permittee(s) must amend the SWPPP as necessary to include odditiond <br />requirements, such m additional or modified BMPs, designed to correct problems <br />ktenUfied or address situations whenever. <br />1. There a a change in design, construction, operation, maintenance, weather r <br />season conditions that has a significant effect on the discharge of pollutants to <br />surface waters or underground water; <br />2. Inspections or investigations by site operators, toad, state or federal officials <br />indicate the SWPPP is not effective in eliminating or significantly minimizing the <br />discharge of pollutants to surfer* water or rmdrgro red waters or that the <br />discharges are causing water quality standard ezceodances, or <br />3. The SWPPP Is not achieving the general objectives of controlling pollutants r storm <br />water discharges associated with construction activity; or tie SWPPP is not <br />consistent with the terns and condition of the permit <br />4. At any fkne after permit coverage a effective, the MPCA may determine that the <br />project's stem water Recharges• may cause, hove reasonable potential to cause, or <br />contrbute to no- attainment of any applicable water quality standard - N MPCA <br />makes such a determnotion, the MPCA .81 notify the Permittee(a) a writing. in <br />response, the Permttes(s) must dewlap a supplemental BMP cotton pion or <br />appropriate 511PPP amendment. describing SWPPP modifications to address the <br />Identified 0000000 and =bait information requested by the MPCA, which may <br />naiad. an individual permit application. If MPCA's ,mitten notification requires a <br />response, theme to respond within the specified tfinefrrne constitutes a permit <br />violation. <br />FINAL STABILIZATION <br />The Permltee(s) must ensure find stabilization of the site The Pemdtee(s) most <br />submit o Notkoe of Termination within 30 days after fad stabilization le complete. <br />or another owner/operator (Permlttee) has assumed control over di areas of the <br />site that have not undergone final stabilization. Find stabilization can be achieved <br />in one of the following ways <br />1. M soil disturbing at the site hove been completed and ail soils most be stabilized <br />by a onlorrn perennial vegetative cover with o density of 70 percent over the <br />entire previous surface ores, or other equivalent means necessary to prevent cog <br />fakers under ewive .eond/feons and: <br />a M drainage ditches, constructed to drain water from the site after construction is <br />complete, must be stabilized to preclude erosion; <br />b. M tempo synthetic, and structural trod= prevention and sediment contra <br />Best Management Plow (such as elt fence) mud be removed as poi of the site <br />final stabilization; and <br />c The Pennitee(s) must dem out all sediment from =san d <br />y0es a from <br />Maim sedimentation aim that ore to be used as permanent water quality <br />management basins Sedknent must be stabilized to prevent It from being wasted <br />bock Into the basin, conveyance and drainage ways discharging off-site or to <br />surface waters The dean out of permanent basins must be sufficient to return <br />the basin to design capacity. <br />2. For residential construction only,- find stabilization nos been achieved when <br />temporary erosion protection and down gradient perimeter - control for individual lots <br />has been completed and the residence hos been transferred to the homeowner. <br />Additionally, the Permits. must distribute the MPCA 'homeowner fact sheet' to the <br />homeowner to inform the homeowner of the need for, and benefit. of, find <br />stobltratlon. <br />RECORD DETENTION <br />The SWPPP, all changes to ft, and 'inspections and maintenance records must be <br />kept at the site during construction by the Permtee who has operational control <br />of that potion of the sits The SWPPP. can be kept In either the field off of in <br />an on -site vehicle. <br />M <br />owner(s) must keep is SYPPP, along with the fo0owng additional records, on <br />flee for three (3) years offer submitted of the NOT os outlined in TERMINATION OF <br />COVERAGE This does not ,elude any records after eubmlttd of the NOT. <br />1.
