30 CFR 816.151 - What additional requirements apply to primary roads?
(b)Certification. The construction or reconstruction of primary roads must be certified in a report to the regulatory authority by a qualified registered professional engineer, or in any state that authorizes land surveyors to certify the construction or reconstruction of primary roads, a qualified registered professional land surveyor with experience in the design and construction of roads. The report must indicate that the primary road has been constructed or reconstructed as designed and in accordance with the approved plan.
(1) To minimize erosion, a primary road must be located, insofar as is practicable, on the most stable available surface.
(e)Drainage control. In accordance with the approved plan -
(1) Each primary road must be constructed, or reconstructed, and maintained to have adequate drainage control, using structures such as, but not limited to, bridges, ditches, cross drains, and ditch relief drains. The drainage control system must be designed to safely pass the peak runoff from the 10-year, 6-hour precipitation event, or any greater event specified by the regulatory authority.
(2) Drainage pipes and culverts must be installed as designed, and maintained in a free and operating condition and to prevent or control erosion at inlets and outlets.
(4) Culverts must be installed and maintained to sustain the vertical soil pressure, the passive resistance of the foundation, and the weight of vehicles using the road.
(6) Except as provided in paragraph (d)(2) of this section, structures for perennial or intermittent stream channel crossings must be made using bridges, culverts, low-water crossings, or other structures designed, constructed, and maintained using current prudent engineering practices. The regulatory authority must ensure that low-water crossings are designed, constructed, and maintained to prevent erosion of the structure or streambed and additional contributions of suspended solids to streamflow.
(f)Surfacing. Primary roads must be surfaced with material approved by the regulatory authority as being sufficiently durable for the anticipated volume of traffic and the weight and speed of vehicles using the road.
