(A) General.
(1) Sections of utility facilities crossing roadways will be constructed with materials more durable than usual to ensure a long, trouble-free service life and to minimize the probability of interference to the roadway's primary function.
(2) As minimums, the following standards and codes will be observed where applicable. Should a conflict arise between 2 or more standards, the County Roads Department will decide which governs:
U.S. Department of Transportation - Pipeline Safety Standards
Maryland Public Service Commission
Maryland Occupational Health & Safety - MOSH
MSHA Utility Ordinance Manual
Standards for Highways & Incidental Structures - MDOT
American Petroleum Institute
American National Standards Institute
American Society for Testing and Materials
American Water Works Association
American Gas Association
American Welding Society
American Society of Mechanical Engineers
American Society of Civil Engineers
National Electric Code
National Electric Safety Code
National Association of Corrosion Engineers
National Fire Protection Association
Occupational Health and Safety Administration - OSHA
Standard Specifications for Construction & Materials - MDOT
(3) Guy wires within 6 feet of the ground will be sheathed in heavy high visibility plastic tubing of 1½" minimum diameter.
(4) Wood poles will be used except where steel poles are necessary to eliminate dangerous or difficult guying. Damaged or rotted poles will be replaced as quickly as possible.
(5) The utility's design of any manhole, vault, or similar underground appurtenance is subject to the prior approval of the County Roads Department. On crossings, such a facility shall normally be located between the ditch and right-of-way line with the top elevation of the cover of any access opening being level with or below the finished grade. Such facilities must be constructed in a manner and at locations that will not interfere with maintenance of the roadway.
(B) Piping.
(1) Pipe utilized for the transportation of gases other than natural gases, all petroleum products, all other flammable products and explosives or hazardous substances shall be made of steel. Low and medium pressure natural gas distribution lines may be made of either steel or polyethylene.
(2) Other utilities may be transported in pipe meeting the utility standard for the material being transmitted.
(3) When crossing a roadway without sleeving such as in the instance of the use of ductile iron pipe. Prior approval by the County Roads Department will be required.
(4) All ferrous pipe surfaces shall be protected against corrosion by a combination of factory applied coating(s) with related field measures as required and a cathodic protection system.
(5) Field welds shall be made and inspected in accordance with USDOT Pipe Line Safety Standards CFR Title 49, Part 192, Subpart E.
(6) All joints shall be protected and electrically insulated from the surrounding soil in a manner at least equivalent to the protection and insulation given to the pipe proper.
(7) Generally, the pipe will have to be jacked across the roadway right-of-way. Protection shall be provided to the coated surface of the pipe by having a mill applied coating as appropriate to the pipe size.
(8) An alternate method of installing concrete pipe shall be to jack a casing pipe (sleeve) across the roadway. The concrete pipe (carrier) would then be grouted into place within the casing. This method includes the assumption that the concrete pipe being used does not require a cathodic protection system to protect its metal elements.
(C) Testing. All installed piping within the county right-of-way will be tested as required by USDOT Pipe Line Safety Standards.
