Effect:of a state permit._This general permit does not convey any:prope;[ty rights in either real • or personal property or any exclusive privileges,:nor does it authorize any injury to private property or invasion.of:personal rights,:or any infringement of federal; state or local law or.regulations. ::0. State law. Nothing in this:general permit shall be construed to preclude the institution of any legal: action under, or relieve the operator from any responsibilities, liabilities, or penalties established pursuant to any other state law or regulation or under authority preserved by§ 510 of the Clean Water Act. Except as provided in general permit conditions on "bypassing" (Part Ill U) and "upset" (Part Ill V), nothing in this general permit shall be construed to relieve the:operato_r - • from civil and .criminal penalties for noncompliance. :P. Oil and hazardous substance liability. Nothing in this general permit shall be construed to • :preclude the institution of :any legal::action or relieve:the operator from any responsibilities, - liabilities, or penalties to which the:operator is or may be subject under§§:62.1-44.34:14 through 62.1-44.34:23 of the.State Water Control:Law or§ 311 of the:Clean Water Act. .: . Q. Proper operation and maintenance. The operator shall at .all: times properly operate and: maintain all facilities and s stems of treatment and related a y treatment (andppurtenances); which are installed or used by the operator to achieve compliance with the conditions of this general permit. Proper operation:and maintenance also includes:effective plant performance, adequate funding; adequate staffing; and adequate laboratory and process controls; including-appropriate :.. quality assurance procedures.. This provision requires the operation of back-up or auxiliary :.. facilities or similar systems, which are installed by the operator only when:the operation is necessary to achieve compliance with the conditions of this general permit: R. Disposal of solids or:sludges::Solids, sludges or other pollutants removed in the course of • treatment or management of pollutants shall be.disposed.of in a manner.so as to prevent any -pollutant from such materials from entering surface waters and in compliance with all applicable state and federal laws and regulations. Page24 of 26, S. .Duty to mitigate.The operator shall take all steps to minimize or prevent any discharge in : violation of this general:permit that has a reasonable likelihood-of adversely affecting .human health or the environment. T. Need to halt or reduce activity:not a defense. It shall not be:a defense for an operator 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.general permit. U. Bypass. 1. "Bypass," as defined in 9VAC25-870-10; means the intentional diversion of waste streams from any portion of p,treatment facility.The operator may allow any bypass to occur that does not cause effluent limitations to be exceeded, but:only if it also is for essential maintenance to ensure efficient operation:°These bypasses are not subject to the provisions:of Part III U 2 and 2: ._Notice: a. Anticipated .bypass. If the operator knows in advance of the need for a bypass, the operator shall submit prior notice to the department, if possible at least 10 days before the : date of the bypass. b: Unanticipated bypass. The operator shall submit notice of an unanticipated bypass as required in Part.III I. ... 3. Prohibition Of bypass... .. a. Except as provided in Part III U 1; bypass is prohibited,and the board or department may take enforcement action against an operator for bypass unless: Bypass was Unavoidable to:prevent loss Of life, personal injury, or severe property : :damage. Severe property damage means substantial physical damage to property, damage to the treatment facilities that causes them.:to become inoperable, or. .: substantial and permanent loss of:natural resources that:can reasonably be expected.: to occur. in the absence of a bypass. :Severe property: damage:does not mean economic loss caused by delays in production; : (2) 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. This-condition is_not satisfied if adequate back-up equipment should have been installed in:the exercise::of reasonable engineering judgment to prevent a bypass that occurred during normal periods of equipment downtime or preventive maintenance; and:• (3) The operator submitted notices as required:under Part III U 2. b. The department may approve an anticipated bypass, after considering its adverse effects, if the department determines that it will meet the three conditions listed in Part Hip 3 a: Page 25 of 26 V. Upset. . • 1. An "upset," as defined in,9VAC25-870-1:Q,:means an exceptional incident in which there:is: ; unintentional and temporary noncompliance with technology-based, state permit effluent limitations:because ,of factors beyond the reasonable control of the operator. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, .:lack of preventive.:maintenance, or careless or:improper:operation: 2. An upset constitutes. an affirmative defense:to an action brought for noncompliance with technology-based state permit effluent limitations if the:requirements of Part Ill V 4 are met. A determination made during administrative review of claims:that noncompliance was caused by upset;:and before an action for noncompliance; is not a final administrative action subject to judicial review. 3. .An upset does not include noncompliance to the extent caused by operational error, • improperly:designed treatment facilities;:inadequate treatment facilities, lack of'preventative maintenance,:or careless Or improper operation. 4. An operator who wishes to establish:the affirmative defense of upset shall demonstrate, : through properly signed, contemporaneous operating logs:or other relevant evidence that: a: An upset occurred and that the operator can identify the cause of the upset; b. The permitted facility was at the time being properly,operated;: c. The operator submitted notice of the upset as required in Part III I; and d. The operator complied with any remedial measures required under Part III S. 5. In any enforcement proceeding, the operator seeking to:establish the occurrence of an upset has the'burden of proof. .. W. Inspection and entry. The operator:shall lalloW the'department.as the board's designee, the:: VSMP authority, EPA,: or an authorized representative of either entity (including an authorized • contractor), upon presentation•of credentials:and other documents as:may be required by law to: 1. Enter upon .the operator's premises where a regulated facility or activity is .located or: Conducted;or where records:shall be kept under the conditions of:this:general:permit 2. Have:access to and copy, at reasonable times, any records that shall be kept under the conditions of this general permit; 3. Inspect and photograph at reasonable times:any facilities; equipment (including monitoring and control equipment), practices,:or operations regulated or required under this general : permit; and - 4. Sample or monitor at.reasonable times, for the purposes of ensuring state permit compliance : or as otherwise authorized by the:Clean Water Act or the Virginia Stormwater Management_: Act, any substances or parameters at any location: • Page 26 of 26. For purposes of this section, the time for inspection:shall be deemed reasonable:d uring regular business hours, and whenever the facility is discharging. Nothing contained herein shall make:an inspection unreasonable during an'emergency. X. State permit actions. State permit coverage may be modified, revoked and reissued, or terminated for cause. •The filing of a request by the operator for a state permit modification, :revocation and: reissuance,.or termination, or a notification of planned changes or anticipated noncompliance does not stay any state permit condition. Y. Transfer of state permit coverage. 1. State permits are not transferable to any person except after.notice to the department.:Except as provided in Part III Y 2, a state permit may be transferred by the operator to a new operator only if.'the state:permit has been modified or revoked and reissued, or a minor modification made; to identify the: new operator and:incorporate such other requirements as may be necessary under the.Virginia Stormwater Management Act and the Clean Water Act. 2. As an alternative to transfers under Part :III Y 1, this state permit may:be automatically transferred to a new operator if: a. The current operator notifies the department:at least 30 days in advance of the proposed • transfer of the title to the facility or property; b. The notice includes a written agreement between •the existing and..new operators containing a specific date for transfer of state permit responsibility, coverage, and,liability • :._ between them; and c. The department does not notify the existing operator and the proposed new operator of its intent to modify or revoke and reissue the state permit:.If this notice is not received,the transfer is effective on the date specified in the agreement mentioned in Part ill Y2 b. - 3: :For ongoing construction activity involving a change of operator,the new operator shall accept and maintain the existing SWPPP, or prepare and:implement a new SWPPP prior to taking . over:operations at the site. Z: Severability:. The provisions of this general permit are severable, and if any provision of this general:permit or the application of any provision of this state permit to any circumstance; is held. invalid, the application of such provision to other circumstances and the remainder of.this general: . .• permit shall not be affected thereby.
