(A) The project site owner of a major project site requiring a construction plan must initiate, manage, and complete construction activities, or must otherwise cause the initiation, managements, and completion of construction activities at the project site in accordance with the requirements and provisions of this section.
(B) The project site owner of a major project site must implement and manage, or must otherwise cause the implementation and management of the project site's storm water quality.
(C) For every project site regulated under this subchapter, the project site owner, individual project site operator, individual lot owner, contractor, subcontractor, homeowner, and resident of a regulated project site must initiate, manage, and complete, or cause the initiation, management, and completion of construction activities at a project site in accordance, at a minimum, with the following requirements and provisions of this section that are applicable to the project site according to this subchapter:
(1) Sediment-laden water which otherwise would flow from the project site must be treated by erosion and sediment control measures appropriate to minimize sedimentation.
(2) Appropriate measures must be implemented to minimize or eliminate wastes or unused building materials, including garbage, debris, cleaning wastes, wastewater, concrete truck washout, and other substances from being carried from the project site by runoff or wind. Identification of areas where concrete truck washout is permissible must be clearly posted at appropriate areas of the project site. Wastes and unused building materials must be managed and disposed of in accordance with all applicable statutes and regulations.
(3) An adequate stable construction site access must be installed at each point of construction traffic ingress to and egress from a project site.
(4) Public or private roadways must be kept cleared of accumulated sediment that is a result of runoff or tracking. Bulk clearing of sediment must not include flushing the area with water. Cleared sediment must be redistributed or disposed of in a manner that is in accordance with applicable statutes and regulations.
(5) Storm water runoff leaving a project site must be discharged in a manner that is consistent with applicable federal, state, and local laws and rules.
(6) The project site owner must post a notice near the main entrance of the project site. For linear project sites such as a pipeline or highway, the notice must be placed in a publicly accessible location near the project field office. The notice must be maintained in a legible condition and contain the following information:
(a) Copy of the completed NOI letter and the NPDES permit number, where applicable;
(b) Name, company name, telephone number, e-mail address (if available), and address of the project site owner or a local contact person; and
(c) Location of the construction plan if the project does not have an on-site location to store the plan.
(7) The permit and posting of the notice under division (C)(6) above does not provide the public with any right to trespass on a project site for any reason, and does not require that the project site owner allow members of the public access to the project site.
(8) The Storm Water Pollution Prevention Plan must serve as a guideline for storm water quality, but will not be interpreted as the only basis for implementation of storm water quality measures for a project site. The project site owner is responsible for implementing, in accordance with this subchapter, all measures necessary to adequately prevent polluted storm water runoff from the project site.
(9) The project site owner must inform all general contractors, construction management firms, grading or excavating contractors, utility contractors, and the individual lot operators of the terms and conditions of this subchapter and the conditions and standards of the Storm Water Pollution Prevention Plan and the schedule for proposed implementation of the plan.
(10) Phasing of construction activities must be used, where possible, to minimize disturbance of large areas of land.
(11) Appropriate storm water quality and quantity control measures must be planned, installed, managed, and monitored as part of an erosion and sediment control system. The measures shall be approved by the Town of Chandler.
(12) All storm water quality measures must be planned, installed, managed, and monitored under the guidance of a trained individual.
(13) Collected storm water runoff leaving a project site must be either discharged directly into a well-defined, stable receiving channel, or diffused and released to adjacent property by an adequate method that does not cause an erosion, sediment, or pollution problem on the adjacent property.
(14) Drainage channels and swales must be sized, configured, constructed, and adequately protected so that their final gradients and resultant velocities will not cause erosion in the receiving channel or at the outlet.
(15) Natural features, including wetlands and sinkholes, must be protected from pollutants associated with storm water runoff.
(16) Unvegetated areas that are scheduled or likely to be inactive for 15 days or more must be temporarily or permanently stabilized with measures appropriate for the season to minimize erosion potential. Alternative measures to temporary or permanent stabilization are acceptable if the project site owner, or the project site owner's designated representative, can demonstrate the implementation of appropriate erosion and sediment control measures are adequate to prevent sediment discharge. Vegetated areas with a density of less than 70% must be re-stabilized using appropriate methods to minimize erosion.
(17) During the period of construction activities, all storm water quality measures, ECMs, and BMPs necessary to meet the requirements of this subchapter must be maintained in working order.
(18) The project site owner must implement a self-monitoring program that includes the following requirements from the initiation to the completion of construction activities at the project site:
(a) A trained individual must perform a written evaluation of the project site:
1. By the end of the next business day following a measurable storm event; and
2. At a minimum of 1 time per week.
(b) The evaluation must address:
1. The maintenance of existing storm water quality measures to ensure they are functioning properly; and
2. Identify additional measures necessary to remain in compliance with this subchapter and all applicable statutes and rules.
(c) Written evaluation reports must include:
1. The name of the individual performing the evaluation;
2. The date of the evaluation;
3. Problems identified at the project site; and
4. Details of corrective actions recommended and completed.
(d) All evaluation reports for the project site must be made available to the inspecting authority within 48 hours of a request.
(19) Proper storage and handling of materials such as fuels or hazardous wastes must be implemented and managed. Spill prevention and clean-up measures must be planned and implemented to minimize the potential for pollutants to contaminate surface or ground water or degrade soil quality.
(20) Final stabilization of a project site must be achieved by the following criteria:
(a) All land disturbing activities have been completed and a uniform (for example, evenly distributed, without large bare areas) perennial vegetative cover with a minimum density of 70% has been established on all unpaved areas and areas not covered by permanent structures, or equivalent permanent stabilization measures have been employed; and
(b) For construction projects on land used for agricultural purposes, the site is returned to its pre-construction agricultural use, or disturbed areas not previously used for agricultural production, such as filter strips and areas that are not being returned to their pre-construction agricultural use, must meet the final stabilization requirements in division (C)(20)(a) above.
