Kitzhaber, MD, Governor Western Region Eugene Office 165 East 7th Avenue, Suite 100 Eugene, OR 97401 (541) 686-7838 FAX (541) 686-7551 TTY 711 June 12, 2014 Mr. Michael Murphy City Administrator City of Port Orford P.O. Box 310 Port Orford, OR 97465 RE: Draft 1997-00463-1 401 Water Quality Certification for City of Port Orford Maintenance Dredging, Port Orford, Curry County, Oregon Dear Mr. Murphy: The Department of Environmental Quality (DEQ) has reviewed the U.S. Army Corps of Engineers Permit (USACE) Application NWP-1997-00463-1, received by DEQ on May 22, 2014. The applicant, the City of Port Orford, proposes maintenance dredging to remove sediment from Port Orford’s Raw Water impoundment water intake structure. The project is located on North Fork Hubbard Creek at River Mile 1, in the City of Port Orford, Curry County, Oregon (Section 4, T33S/R15W). This project was originally certified on March 11, 2008, and has been allowed to expire. The City of Port Orford is reapplying for certification. Project Description: Project elements include: removing up to 25 cubic yards of material annually in an area approximately 250 feet long, 150 feet wide and up to 9 feet deep from the drinking water reservoir using a hydraulic dredge; installing silt fencing and hay bales to control sediment releases; dewatering sediment on site, and disposing sediment upland to a settling pond. Status of Affected Water of the State: The North Fork Hubbard Creek is a tributary to Hubbard Creek. Hubbard Creek is classified as water quality limited for the parameters of Flow Modification and Habitat Modification. The above listed parameters impair the following beneficial uses in Hubbard Creek: resident fish and aquatic life, salmonid fish rearing and spawning, and anadromous fish passage. Based on the application materials, DEQ is reasonably assured that implementation of the Project will be consistent with applicable provisions of Section 301, 302, 303, 306, and 307 of the federal Clean Water Act, state water quality standards set forth in OAR Chapter 340 Division 41, and other appropriate requirements of state law, provided the following conditions are incorporated into the USACE permit and strictly adhered to by the applicant. 401 CERTIFICATION CONDITIONS 1) Duration of Certification: This 401 WQC is valid until expiration of the current USACE permit (NWP#1997-00463-1). A new 401 WQC must be obtained prior to any substantial modification of the USACE permit. 2) Fish protection/Oregon Department of Fish and Wildlife timing: In-water work is allowed only between July 1 and November 30. 3) Aquatic life movements: Any activity that may substantially disrupt the movement of those species of aquatic life indigenous to the water body, including those species that normally migrate through the area, is prohibited. Unobstructed fish passage must be provided at all times during any authorized activity. Exceptions must be reviewed and approved in writing in advance by ODFW and the NMFS. 4) Turbidity: All practical Best Management Practices (BMPs) on disturbed banks and within waters must be implemented to minimize turbidity during in-water work. Any activity that causes turbidity to exceed 10% above natural turbidities is prohibited except as specifically provided below. a. Monitoring: Visual turbidity monitoring must be conducted and recorded as described below. Monitoring must occur each day during daylight hours when in-water work is being conducted. Visual gauging is acceptable, however turbidity that is visible over background is considered an exceedance of the standard. i. Representative Background Point: a sample or observation must be taken every two hours at a relatively undisturbed area approximately 100 feet upcurrent from in-water disturbance to establish background turbidity levels for each monitoring cycle. Background turbiditiy, location, date, and time must be recorded prior to monitoring downcurrent. ii. Compliance Point: Visual monitoring must occur every two hours, at the dredge site and approximately 300 feet downcurrent from the disturbance, at approximately mid-depth and within any visible plume, and be compared against the background measurement or observation. The turbidity, location, date, and time must be recorded for each sample or observation. b. Compliance: Results from the compliance points must be compared to the background levels taken during each monitoring interval. Exceedances are allowed as follows: VISUAL MONITORING No plume observed Plume observed Continue to monitor every 2 hours Modify BMPs & continue to monitor every 4 hours Continue to monitor every 2 hours Stop work after 4 hours with an observed plume A visible plume is considered an exceedance. c. If an exceedance over the background level occurs at any time, the applicant must modify the activity and continue to monitor every two hours. If an exceedance over the background level continues after the second monitoring interval, the activity must stop. If, however, turbidity levels return to background at or after second monitoring level due to implementation of BMPs or natural attenuation, work may continue with appropriate monitoring as above. d. Reporting: The applicant must make available copies of daily logs for turbidity monitoring to DEQ, NMFS, USFWS, and ODFW upon request. The log must include: calibration documentation (if using an instrument); background NTUs or observation; compliance point NTUs or observation’ comparison of the points in NTUs or narrative; and location; date; time; and tidal stage (if applicable) for each reading. Additionally, a narrative must be prepared discussing all exceedances with subsequent monitoring, actions taken, and the effectiveness of the actions. 5) Dredging and disposal methods: a. Suitable for Unconfined In-Water Disposal i. Dredging method (e.g., backhoe operated from bank, toothed clamshell bucket, close-lipped clamshell bucket, hydraulic suction) is not limited, except as outlined in the application. ii. Dewatering during dredging (e.g., over water from bucket; through filtered outlets or after settling in a tank, bin, barge, pond, etc.) is not limited. iii. Dredged material disposal method (e.g., unconfined in-water, upland reuse, confined upland disposal facility, landfill) not limited. DEQ clean fill determination or Solid Waste Letter of Authorization is required for any manner of upland disposal. iv. Discharge of return water (e.g., controlled release from confined upland disposal facility after settling) is not limited. v. Leave surface management (e.g., over or under dredge to clean material, overdredge and cap, cap) is not required. b. Complete containment of in-water work areas from the active flowing stream by using silt curtains, cofferdams, inflatable bags, geo blocks, sandbags, sheet pilings or similar materials, is encouraged. The applicant is referred to Appendix D of DEQ’s Oregon Sediment and Erosion Control Manual, April 2005, for isolation techniques (www.deq.state.or.us/wq/stormwater/docs/escmanual/appxd/pdf). c. Floating containment and absorbance booms must be maintained on site throughout implementation of the project and deployed in the event that any sheen or floating debris is detected during project operations. d. Employ techniques to minimize sediment disturbance and distribution through the water column. i. Sequence or phase work activities to minimize the extent and duration of inwater disturbances; ii. Employ an experienced equipment operator; iii. Implement bucket control techniques, such as: 1. Position the barge as close to the dredge as possible to minimize decant water and sediment returning to the water; 2. Do not overfill the bucket; 3. Close the bucket as slowly as possible on the bottom; 4. Pause before hoisting the bucket off of the bottom to allow any overage to settle near the bottom; 5. Hoist load very slowly; 6. Move the bucket quickly to the barge to avoid decant water from being discharged to surface waters; 7. "Slam" open the bucket after material is dumped on a barge to dislodge any additional material that is potentially clinging to the bucket; 8. Ensure that all material has dumped into the barge from the bucket before returning for another bite; and 9. Do not dump partial or full buckets of material back into the wetted stream. e. Dredging of holes or sumps below maximum depth and subsequent redistribution of sediment by dredging, dragging, or other means is prohibited. 6) If the dredging operation causes a water quality problem which results in distressed or dying fish, the operator shall immediately: cease operations; take appropriate corrective measures to prevent further environmental damage; collect fish specimens and water samples; and notify DEQ, ODFW, NMFS, and USACE within 24 hours of the incident. 7) Spill Prevention: a. Best management practices (BMPs) shall be employed in order to prevent petroleum products, chemicals, or other deleterious waste materials from entering waters of the State. b. Fuel hoses, oil drums, oil or fuel transfer valves and fittings, etc., must undergo frequent inspection for drips or leaks, and shall be maintained in order to prevent spills into State waters. c. An adequate supply of spill response materials, such as booms and absorbent materials shall be kept at the immediate project site and deployed as necessary. d. The applicant must remove all foreign materials, refuse, and waste from the area and dispose of them properly. 8) Spill and Incident Reporting: a. In the event that petroleum products, chemicals, or any other deleterious materials are discharged into state waters, or onto land with a potential to enter state waters, the discharge must be promptly reported to the Oregon Emergency Response Service (OERS, 1-800-452-0311). Containment and cleanup must begin immediately and be completed as soon as possible. b. If the project operations cause a water quality problem that results in distressed or dying fish, the operator must immediately: cease operations; take appropriate corrective measures to prevent further environmental damage; collect fish specimens and water samples, and notify DEQ, ODFW and other appropriate regulatory agencies. 9) The applicant must notify DEQ of any change in ownership and obtain DEQ review and approval before undertaking any change to the project that might affect water quality. 10) DEQ may modify or revoke this 401 WQC, in accordance with OAR 340-048-0050, in the event of project changes or new information indicating that the project activities are having an adverse impact on state water quality or beneficial uses. 11) A copy of this 401 WQC letter shall be kept on site and readily available for reference by the applicant and its contractors, DEQ, and other appropriate state and local government inspectors. 12) This 401 WQC is invalid if the project is operated in a manner not consistent with the project description contained in the permit application materials. 13) The applicant and its contractors must allow DEQ site access at reasonable times as necessary to monitor compliance with these 401 WQC conditions. If the applicant is dissatisfied with the conditions contained in this certification, a contested case hearing may be requested in accordance with OAR 340-048-0045. Such request must be made in writing to the DEQ Office of Compliance and Enforcement at 811 SW 6th Avenue, Portland Oregon 97204 within 20 days of the mailing of this certification. The DEQ hereby certifies this project in accordance with the Clean Water Act and state rules, with the above conditions.
