Hazardous Materiais.Solid Waste-The Solid Wastes Disposal Sites and Facilities Act C.R.S.30-20-100,et al,and Regulations
<br /> Pertaining to Solid Waste Disposal Sites and Facilities(6 CCR 1007-2),prohibit solid waste disposal without an approved
<br /> Certificate of Designa6on(a landfill permit). The Colorado Hazardous Waste Act C.R.S.25-15-301 et al,and the Colorado
<br /> Hazardous Waste Regulations(6 CCR 1007-3)prohibit the transfer,storage or disposal(TSD)of hazardous waste except at
<br /> permitted TSD sites. There are no permitted landfills or TSD sites within the State Highway Right of Way. Therefore,all solid or
<br /> hazardous wastes that might be generated by the activities of entities entering the State Highway Right of Way must be removed
<br /> from the ROW and disposed of at a peRnitted facility or designated collection point(e.g.,for solid waste,a utility or construction
<br /> company's own dumpster). If pre-existing solid waste or hazardous materials contamination(including oil or petroleum
<br /> contaminated soil,asbestos,chemicals,mine tailings,etc.)is encountered during the pertormance of woric,the permittee shall halt
<br /> work in the affected area and immediatety contact the CDOT Regional Permitting Office for direction as to how to proceed.

<br /> Water Qualitv Certifications Issued bv the CDPHE WQCD-Clean Water Act section 404 permits are often reqwred for the
<br /> discharge of dredged or fill matenal into waters of the U.S., including wetlands. Several rypes of section 404 permits exist,
<br /> including nationwide, regional general,and individual permits. Nationwide perrnits are the most commonly authorized rype for

<br /> that may obstruct,diminish,destroy,change,modify,or vary a natural existing stream or its banks or tributaries,it may be
<br /> necessary to obtain a Senate Bill 40 certifica6on from the Colorado Department of Natural Resources. A stream is defined as 1)
<br /> represented by a solid blue line on USGS 7.5'quadrangle maps;and/or 2)intermittent streams providing live water beneficial to
<br /> fish and wildlife;and/or 3)segments of streams supporting 25%or more cover within 100 yards upstream or downstream of the
<br /> project;and/or 4)segments of streams having wetlands present within 200 yards upstream or downstream of the project measured
<br /> by valley length. The CPW application,as per guidelines agreed upon by CDOT and CPW,can be accessed at

<br /> Erosion and Sediment Control Practices-Any activities that disturb one or more acres of land require a Stortnwater
<br /> Construction Pertnit(SCP)from the CDPHE-WQCD. Erosion&sediment control requirements will be specified in that permit. In
<br /> situations where a stormwater peRnit is not required,all reasonable erosion and sediment control measures should be taken to
<br /> minimize erosion and sedimentation. Control practices should be in accordance with CDOT Standarcl Specifications 107.25,208,
<br /> 213 and 216(httas�//www codot aov/business/desiQnsupqort/cdot-construction-saecifications). The CDOT Erosion Control and
<br /> Stormwater Quality Guide(website: https�//www codot qov/proarams/environmental/landscaae-architecture/erosion-storm-aualitv)
<br /> can also be used to design erosion/sediment controls. Contact Information:Contact the CDPHE-WQCD at(303)692-3500.

<br /> Site Stabilization-All disturbances require a stabiliza6on plan,native seeding or landscape design plan according to applicable
<br /> CDOT Standard Spec�cations 212-217 and 623. The CDOT Erosion Control and Stonnwater Quality Guide should also be used
