The Department may, for enforcement purposes, use any one or a combination of the following actions: A notice of violation shall be issued specifying the need for corrective action if the final stormwater management plan noncompliance is identified; A Stop Work Order shall be issued for the site by the Director if a violation persists; Bonds or securities shall be withheld or the case may be referred for legal action if reasonable efforts to correct the violation have not been undertaken; or In addition to any other sanctions, a civil action or criminal prosecution may be brought against any person in violation of this Code, the Maryland Design Manual, the Prince George's County Design Manual, or this Division. Any step in the enforcement process may be taken at any time, depending on the severity of the violation. Once construction is complete, "as-built" plan certification shall be submitted by either a professional engineer or professional land surveyor licensed in the State of Maryland to ensure that ESD planning techniques, treatment practices, and structural and nonstructural stormwater management measures and conveyance systems comply with the specifications contained in the approved plans. At a minimum, "as-built" certification shall include a set of drawings comparing the approved final stormwater management plan with what was constructed. The Department may require additional information. The Department shall submit notice of construction completion to the Administration on a form supplied by the Administration for each structural stormwater management practice within 45 days of construction completion. The type, number, total drainage area, and total impervious area treated by all ESD techniques and practices shall be reported to the Administration on a site by site basis. If BMPs requiring Prince George's Soil Conservation District approval are constructed, notice of construction completion shall also be submitted to the Soil Conservation District.

The permittee shall provide "as-built" plans certified by a registered professional engineer to be submitted upon completion of a stormwater management facility. The registered professional engineer shall certify that the facility has been constructed as shown on the "as-built" plan and meets the approved final stormwater management plan and specifications. A final inspection shall be conducted upon completion of the stormwater management facility to determine if the completed work is constructed in accordance with the approved final stormwater management plan. The Department shall maintain a permanent file of all inspection reports.

At the discretion of the Department, the certification of a professional engineer registered in the State of Maryland may be accepted in lieu of any inspection required by this Division.

Any stormwater management measure which serves a single lot or facility shall be privately owned and maintained. All stormwater management measures relying on vegetated areas or site features shall be privately owned and maintained unless located on public property. All other stormwater management facilities shall be publicly owned and operated.

Prior to the issuance of any building permit for which stormwater management is required, the County shall require the applicant or owner to execute an inspection and maintenance agreement to include an operation and maintenance plan binding on all subsequent owners of land served by a private stormwater management facility. Such agreement shall provide for access to the facility at reasonable times for regular inspections by the County or its authorized representative to ensure that the facility is maintained in proper working condition to meet design standards. The agreement shall be recorded by the applicant in the land records of the County prior to the issuance of any Use and Occupancy permits for the project. The agreement shall also provide that, if after notice by the Department to correct a violation requiring maintenance work, satisfactory corrections are not made by the owner(s) within a reasonable period of time (30 days maximum), the County may perform all necessary work to place the facility in proper working condition. The owner(s) of the facility shall be assessed the cost of the work and any penalties. This may be accomplished by placing a lien on the property, which may be placed on the tax bill and collected as ordinary taxes by the County.
