MaineDOT’ s Jurisdiction All State and State Aid roads. http://medotmaps.maine.gov/MapViewer/ All Facilities and Appurtenances within the Highway limits must also comply with any applicable National Standards. Where those standards differ from what is stated herein, the higher degree of protection shall prevail.
Maine DOT’ s Jurisdiction The Utility Accommodation Rules govern installations within the limits of state and state- aid Highways, and are the default rules within the limits of state and state-aid Highways in Compact Areas where municipalities do not have their own more stringent rules [35-A MRSA §2503 (21)].
Compliance with Laws current OSHA regulations compliance with the MUTCD applicable requirements of ADA Maine’s requirements for the Protection of Underground Facilities [23MRSA §3360-A] as administered through MPUC and reported to Dig Safe® System, Inc., and each Utility using OKTODIG.
Preferred Corridors Water & Sewer Lines Under the Traveled Way Gas Lines Under the Shoulder Telephone/Electric Conduit Under the Shoulder or Sidewalk
Minimum depth requirements PUC verses MDOT Services-36”MDOT/30”PUC Low Pressure Mains -36” Both High Pressure over 100psi-48”MDOT
Vertical Separation between Utilities 12” PUC & MDOT PROCESS to follow when issues occur Notify affected Utility Come to agreement with affected Utility
PUC-Where there is interference with other subsurface structures, including other utilities, the pipe shall be laid at a clearance distance of not less than twelve (12) inches away from such structures unless adequate shielding is provided to protect the gas pipeline and the other utility. MDOT-Vertical Clearance Between Facilities Where underground Facilities must cross other Facilities or Appurtenances; the angle of such crossing shall be as close to 90 degrees as possible, with a minimum vertical clearance of 1 foot.
Cooperation with Other Authorized Entities Throughout the design and installation of any Facilities and Appurtenances within the Highway limits, Authorized Entities must address the needs of all other Authorized Entities with regard to their existing or Proposed Installations located in the vicinity of another Proposed Installation. This shall include maintaining sufficient offsets from other Facilities and Appurtenances and assuring that all other Authorized Entities have reasonable access to their own Facilities and Appurtenances during construction. Where Authorized Entities are unable to resolve conflicts in accordance with these rules, MaineDOT shall make the final determination.
Horizontal Clearance Between Facilities Unless specifically permitted otherwise, a 3-foot minimum horizontal clearance shall be maintained between all underground Facilities and Appurtenances. Measurement between underground Facilities and Appurtenances shall be taken horizontally from the closest edge of the Facility or Appurtenance. Aboveground pole lines (excepting crossings and services) shall also be included in this standard where those poles occupy a consistent offset. Measurement to a pole line shall be to the nearest face of pole or to the vertical plane established longitudinally through the center of the pole line between poles.
Verification of Separation Requirements All trenchless installation methods are required to have the ability to accurately determine the horizontal and vertical position of the tip instrument when utilities, including drainage structures, are being crossed during installation.
Verification of Separation Requirements Open cut methods would fall under the Dig safe rule. Hand shovel to expose Utility.
Pavement Cuts Wherever pavement is to be cut, all edges shall be cut neat and straight.
Pavement Moratorium A. Light Capital Paving (LCP): No moratorium. B. All other paving overlays of 5/8 inch or more or any “mill and fill” project: 3 years
Pavement Moratorium Cont. C. Any construction work of higher order than an overlay, including new or full construction, reclaiming, “foamed asphalt”, and other forms of rehabilitation, such as partial reconstruction or using recycled asphalt pavement (PMRAP): 5 years
Pavement Moratorium Cont. If the applicant can show that the need for an opening permit could not have been anticipated before the highway was paved and that it has made an effort to investigate alternative installation procedures, MaineDOT may elect to consider an Exception in accordance with Section 14, Exceptions and Appeals.
Pavement Moratorium Cont. In the case where an exception is granted, MaineDOT will normally require a higher standard of repair as shown on the Pavement and Trench Restoration Details in the Appendix. MaineDOT may additionally increase the 10% permit fee.
Inspection All work performed within the Highway limits will be subject to periodic inspection by MaineDOT. In addition, and at MaineDOT’ s discretion, a dedicated MaineDOT or third party inspector may be assigned to oversee any specific projects or work activities to ensure that the state’s interests are sufficiently protected. All costs associated with this inspection shall be borne by the permittee, over and above the permit fee.
