COVERAGE UNDER THIS PERMIT A. Permit Authority and Area 1. Permitting Authority. Under the Clean Water Act’s National Pollutant Discharge Elimination System (NPDES) program the Environmental Protection Agency (EPA) has granted primacy to the state of Utah with its storm water permit program. The Utah Admin. Code R317-8-2.5 authorizes the issuance of General Permits for categories of point sources within the same geographical area with discharges that are from similar types of operations and wastes, and that require similar effluent limitations and monitoring. 2. Permit Area. This Permit Covers all areas of the State of Utah except for Indian lands. The State of the Utah, Department of Environmental Quality, Division of Water Quality (DWQ) does not have permit authority for Indian Lands. Storm water permits for Indian lands within the State must be acquired through EPA Region VIII, except for facilities on the Navajo Reservation or on the Goshute Reservation, which must acquire storm water permits through EPA Region IX. B. Coverage Under this Permit 1. This Permit shall apply to construction dewatering of uncontaminated groundwater or surface water sources due to construction activities, hydrostatic testing of pipelines or other fluids vessels, water used in disinfection of drinking water vessels and other similar discharges in the State of Utah that have no discharge of process wastewater other than those described in this paragraph. 2. Discharges Covered Under this Permit include: a. In-stream dewatering: cofferdams, drill hole or pylon development; b. Surface area dewatering: water pumped from disturbed surface areas (trenches, sumps, excavation pits, similar points of accumulation or other excavations associated with construction activities where sediment-laden ground water or surface water/storm inflow must be removed); and c. Ground water dewatering: water discharged from well development, well pump tests, or pumping of ground water from a construction area. Dewatering wells located within an active area of disturbance is subject to this Permit. Common methods of ground water dewatering from a construction area include sumps, wells, and well-points; and d. Hydrostatic Testing: such as piping systems, gas cylinders, fire extinguishing, storage tanks, boilers, chemical pipelines, and pressure vessels that are tested for strength and leaks. 3. The following discharges are not covered under this Permit: a. This Permit does not authorize discharge from dewatering activities at hazardous waste sites, leaking chemical tanks, the discharge of toxic materials, or discharge of contaminated water, sanitary or industrial wastes (other than what is normally encountered at excavation and construction sites) at any location. b. This Permit does not authorize the discharge of treated groundwater or surface water due to cleanup of spills of hazardous or regulated materials, including fuel spills. c. This Permit does not constitute authorization under 33 U.S.C. § 1344 (Section 404 of the Clean Water Act) of any stream dredging or filling operations. d. Any dewatering discharge that is land applied and does not reach state waters or the storm drain is not regulated under this Permit, although a DWQ Groundwater Discharge Permit may be required. e. An authorization to discharge under this Permit, where the activity discharges to a Construction Dewatering/Hydrostatic Testing Permit No.: UTG70000 Part I - 2 - municipal or private storm drain owned by another party or discharges to private or public lands or water ways, does not convey any rights or authorization to discharge to the above stated location.

Construction Dewatering/Hydrostatic Testing Permit Permit No. UTG07000 Part IV - 12 - IV. COMPLIANCE RESPONSIBILITIES A. Duty to Comply The permittee must comply with all conditions of this Permit. Any Permit noncompliance constitutes a violation of the Act and is grounds for enforcement action; for NOI termination, revocation and reissuance, or modification; or for denial of an NOI. The permittee shall give advance notice to the Director of any planned changes in the permitted facility or activity which may result in noncompliance with Permit requirements. B. Penalties for Violations of Permit Conditions In accordance with Utah Admin. Code § 19-5-115(2), any person who violates a Permit condition implementing provisions of the Act is subject to a civil penalty not to exceed $10,000 per day of such violation. Except as provided at Part IV.G. Bypass of Treatment Facilities and Part IV.H. Upset Conditions, nothing in this Permit shall be construed to relieve the permittee of the civil or criminal penalties for noncompliance. C. Need to Halt or Reduce Activity not a Defense It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this Permit. D. Duty to Mitigate The permittee shall take all reasonable steps to minimize or prevent any discharge in violation of this Permit which has a reasonable likelihood of adversely affecting human health or the environment. E. Proper Operation and Maintenance The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions of this Permit. Proper operation and maintenance also includes adequate laboratory controls and quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems which are installed by a permittee only when the operation is necessary to achieve compliance with the conditions of the Permit. F. Removed Substances Collected screening, grit, solids, sludge, or other pollutants removed in the course of treatment shall be disposed of in such a manner so as to prevent any pollutant from entering any waters of the state or creating a health hazard. Sludge/digester supernatant and filter backwash shall not directly enter either the final effluent or waters of the state by any other direct route. G. Bypass of Treatment Facilities 1. Bypass not exceeding limitations. The permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, but if it is also for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of Part IV.G.2. 2. Prohibition of bypass a. Bypass is prohibited and the Director may take enforcement action against a permittee for a bypass, unless: i. The bypass was unavoidable to prevent loss of human life, personal injury, or severe property damage; Construction Dewatering/Hydrostatic Testing Permit Permit No. UTG07000 Part IV - 13 - ii. There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime.

The permittee submitted notices as required under Part IV.G.3. b. The Director may approve an anticipated bypass, after considering its adverse effects, if the Director determines that it will meet the three conditions listed in Part IV.G.2. 3. Notice a. Anticipated bypass. Except as provided in Part IV.G.2.and in Part IV.G.4., if the permittee knows in advance of the need for a bypass, it shall submit prior notice, at least 90 days before the date of bypass. The prior notice shall include the following unless otherwise waived by the Director: b. Evaluation of alternative to bypass, including cost benefit analysis containing an assessment of anticipated resource damages; c. A specific bypass plan describing the work to be performed including scheduled dates and times. The permittee must notify the Director in advance of any changes to the bypass schedule; d. Description of specific measures to be taken minimize environmental and public health impacts; e. A notification plan sufficient to alert all downstream users, the public and others reasonably expected to be impacted by the bypass; f. A water quality assessment plan to include sufficient monitoring of the receiving water before, during and following the bypass to enable evaluation of public health risks and environmental impacts; and g. Any additional information requested by the Director. 4. Emergency Bypass. Where ninety days advance notice is not possible, the permittee must notify the Director, and the Director of Department of Natural Resources, as soon as it becomes aware of the need to bypass and provide to the Director the information in Part IV.G.3.a. to the extent practicable. 5. Unanticipated Bypass. The permittee shall submit notice of an unanticipated bypass to the Director as required in Part III., Twenty-Four Hour Notice of Noncompliance Reporting. The permittee shall also immediately notify the Director of the Department of Natural Resources, the public and downstream users and shall implement measure to minimize impacts to public health and environment to the extent practicable. H. Upset Conditions 1. Effect of an upset. An upset constitutes an affirmation defense to an action brought for noncompliance with technology-based permit effluent limitations if the requirements of Part IV.G. of this section are met. 2.
