<br /> Discharge of Dredged or Fill Material—404 Permits Administered By the U.S.Army Corps of Engineers, and Section 401
<br /> Water Quality Certifications Issued by the CDPHE WQCD-Corps of Engineers 404 permits are required for the discharge of
<br /> dredged or fill materials into waters of the United States, including wetlands.There are various types of 404 permits,including
<br /> nationwide permits,which are issued for activities with relatively minor impacts. For example,there is a nationwide permit for utility
<br /> line activities(nwp#12). Depending upon the specific circumstances, it is possible that either a"general"or"individual"404 permit
<br /> would be required. If an individual 404 permit is required, section 401 water quality certification from the CDPHE WQCD is also
<br /> required.Contact the appropriate Corps District Regulatory Office for information about what type of 404 permit may be required
<br /> (contact information above .Contact the CDPHE Water Quality Control Division at 303)692-3500.
<br /> Working on or in any stream or its bank-In order to protect and preserve the state's fish and wildlife resources from actions that
<br /> may obstruct,diminish,destroy,change,modify, or vary a natural existing stream or its banks or tributaries, it may be necessary to
<br /> obtain a Senate Bill 40 certification from the Colorado Department of Natural Resources.A stream is defined as 1)represented by a
<br /> solid blue line on USGS 7.5'quadrangle maps;and/or 2)intermittent streams providing live water beneficial to fish and wildlife; and/or
<br /> 3)segments of streams supporting 25%or more cover within 100 yards upstream or downstream of the project;and/or 4)segments of
<br /> streams having wetlands present within 200 yards upstream or downstream of the project measured by valley length.The CPW

<br /> storm sewers, discharges from potable water sources,foundation drains, air conditioning condensation, irrigation water,
<br /> uncontaminated springs,footing drains,water line flushing,flows from riparian habitats and wetlands,and flow from firefighting
<br /> activities.Allowable non-stormwater discharges can be found under Illicit Discharge PDD at: htt s:r';wvrw.codotsgy 2_ru;rarT: /

<br /> Erosion and Sediment Control Practices-For activities requiring a Stormwater Construction Permit, erosion control requirements
<br /> will be specified in that permit.In situations where a stormwater permit is not required, all reasonable measures should be taken to
<br /> minimize erosion and sedimentation according to CDOT Standard Specifications 107.25,208,213 and 216(htt; s : >,.cr n •c
<br /> business/desi insu_,:,ort/2011 construction si ecificatons/2011-S ecs/201 1 s1•ecs book).All disturbances require a stabilization plan,
<br /> native seeding or landscape design plan according to applicable CDOT Standard Specifications 212-217 and 623. The CDOT
<br /> Erosion Control and Stormwater Quality Guide(available from the Bid Plans Office at(303)757-9313)should be used to design
<br /> erosion controls and restore disturbed vegetation.
