e length of the road minimizes any adverse effects on waters of the United States and <br />ust be as near as possible to pre - construction contours and elevations (e.g., at grade <br />rduroy roads or geotextile/gravel roads). Access roads constructed above pre - <br />nstruction contours and elevations in waters of the United States must be properly <br />idged or culverted to maintain surface flows. <br />This NWP may authorize utility lines in or affecting navigable waters of the <br />sited States even if there is no associated discharge of dredged or fill material (See 33 <br />FR Part 322). Overhead utility lines constructed over section 10 waters and utility lines <br />at are routed in or under section 10 waters without a discharge of dredged or fill <br />aterial require a section 10 permit. <br />This NWP also authorizes temporary structures, fills, and work necessary to <br />induct the utility line activity. Appropriate measures must be taken to maintain normal <br />â–ºwnstream flows and minimize flooding to the maximum extent practicable, when <br />mporary structures, work, and discharges, including cofferdams, are necessary for <br />instruction activities, access fills, or dewatering of construction sites. Temporary fills <br />ust consist of materials, and be placed in a manner, that will not be eroded by expected <br />gh flows. Temporary fills must be removed in their entirety and the affected areas <br />turned to pre- construction elevations. The areas affected by temporary fills must be <br />vegetated, as appropriate. <br />Notification: The permittee must submit a pre- construction notification to the <br />strict engineer prior to commencing the activity if any of the following criteria are met: <br />) the activity involves mechanized land clearing in a forested wetland for the utility line <br />;ht -of -way; (2) a section 10 permit is required; (3) the utility line in waters of the <br />fited States, excluding overhead lines, exceeds 500 feet; (4) the utility line is placed <br />ithin a jurisdictional area (i.e., water of the United States), and it runs parallel to a <br />-earn bed that is within that jurisdictional area; (5) discharges that result in the loss of <br />eater than 1/10 -acre of waters of the United States; (6) permanent access roads are <br />nstructed above grade in waters of the United States for a distance of more than 500 <br />-t; or (7) permanent access roads are constructed in waters of the United States with <br />ipervious materials. (Sections 10 and 404) <br />Note 1: Where the proposed utility line is constructed or installed in navigable <br />hers of the United States (i.e., section 10 waters), copies of the pre- construction <br />itification and NWP verification will be sent by the Corps to the National Oceanic and <br />!mospheric Administration (NOAA), National Ocean Service (NOS), for charting the <br />ility line to protect navigation. <br />Note 2: Access roads used for both construction and maintenance may be <br />thorized, provided they meet the terms and conditions of this NWP. Access roads used <br />lely for construction of the utility line must be removed upon completion of the work, <br />cordance with the requirements for temporary fills. <br />Note 3: Pipes or pipelines used to transport gaseous, liquid, liquescent, or slurry <br />bstances over navigable waters of the United States are considered to be bridges, not <br />ility lines, and may require a permit from the U.S. Coast Guard pursuant to Section 9 of <br />Rivers and Harbors Act of 1899. However, any discharges of dredged or fill material <br />to waters of the United States associated with such pipelines will require a section 404 <br />rmit (see NWP 15). <br />
