[14]

Section 6: Erosion and Sediment Controls

Control measures at the construction site are selected, installed, implemented, and maintained to minimize pollutants in the discharge as necessary to meet applicable water quality standards.

The objectives of this ESCP include:

• Stabilize the site as soon as possible (targeting the preparation and implementation of erosion and sediment controls to get the site to final grade, and either permanently or temporarily stabilize all bare soil areas as soon as possible).

• Perimeter controls will be installed before ground disturbing activities are initiated.

• Perimeter protection will remain in place until final stabilization has been achieved.

• Slopes and channels will be protected by conveying concentrated stormwater runoff around the top of slopes and stabilize slopes as soon as possible. Avoid disturbing natural channels and the vegetation along natural channels as much as possible.

• Divert stormwater coming on to the site by conveying it safely around, through, or under the work area. (Divert the clean water, trap the dirty water.)

• Protect receiving waters and other environmentally sensitive waters or areas adjacent to the site.

• Follow pollution prevention measures by providing proper containers for waste and garbage at the site. Store hazardous materials and chemicals so that they are not exposed to stormwater.

• Minimize the area and duration of exposed soils. Clear only land that will be under construction in the near future.

6.1 Perimeter Controls

All Perimeter Sediment Controls will be installed prior to ground disturbing activities taking place. There will be no clearing or grubbing outside the physical clearance limits.

Locations and design specifications of BMPs are shown on the erosion and sediment control plan sheets in TAB 6.

The following perimeter controls will be implemented:

Measure: Silt Fence, Orange Construction Fencing, Fiber Rolls Implementation: Place orange construction fence around construction site and areas not to be disturbed prior to beginning construction disturbance activities. Place silt fence and/or fiber rolls between work area and stream(s) prior to construction disturbance. Place fiber rolls around toe of material stockpiles.

Maintenance: As needed

Note: Add additional measures used during construction.

[15]

6.2 Sediment Track-Out

6.12 Dewatering Practices

Discharge of ground water or accumulated stormwater that is removed from excavations, trenches, foundations, etc. into surface waters is prohibited unless such waters are first effectively managed by appropriate sediment controls. Uncontaminated non-turbid dewatering water can be discharge without being routed to a control.

☐ Not applicable to this project

[20]

Measure: Cofferdams and dewatering pumps with spill containments kit and sediment socks.

Discharge storm water to natural vegetative buffer. Temporary bridge spanning wetted perimeter for side channel/upstream pools at Bridge 07894 (Barnard).

Implementation: Prior to and during dewatering/construction activities

Maintenance: As needed

6.13 Erosion Control and Stabilization

Commence temporary soil stabilization measures immediately if no further disturbance of an area of the site or stockpile is expected within the next 14 days. Complete temporary soil stabilization measures to disturbed sites or stockpiles as soon as practicable, but no later than 7 days of last disturbance.

Provide for temporary stabilization of all exposed soil prior to winter construction shut down. Specify whether stabilization measure is temporary or permanent.

☒ Temporary Measures:

Measure: Stockpiles covered in tarps.

Implementation: Stockpiles will be covered in tarps per 1200-CA requirements.

Note: Add additional measures used during construction. If using seed, provide composition of seed mix and other plant types used to establish temporary cover.

☒ Permanent Measures:

Practice/Measure: Riprap and willow stakes

Implementation: Contractor will perform riprap placement as specified in the plans. Willow stakes will be planted in the riprap and along the bank as verified in the field by the CO.

6.14 Removal of BMPs

Remove erosion and sediment control BMPs that are no longer needed and leave in good working order those BMPs that will remain at the construction site after close-out.

[21]

BMPs are no longer needed when the site that the BMP is protecting has reached final stabilization.

Final stabilization means:

• All ground disturbing activities at the site have been completed, AND

• Vegetation has been established that provides a uniform perennial vegetative cover with a density of 70% of the natural vegetative cover prior to construction.

• For sites where it is difficult to establish 70 percent coverage (e.g., arid, semiarid or drought-stricken areas), the registrant must cover exposed soil between planted or seeded areas with bio or photo degradable controls designed to prevent erosion without active maintenance or propose a site-specific plan to DEQ for approval.

Document arid/semi-arid conditions in ESCP

• Effective non-vegetative stabilization is in-place such as rip rap, gabions, geotextiles, rock, aggregate etc.

6.15 Post Construction Measures

Responsibility for NPDES permit compliance after construction close-out will be the responsibility of:

☐ FHWA/WFLHD

☐ Land Management/Owner Agency Specify Agency: Choose an item.

☒ County/State DOT

Section 7: Operational Controls/Good Housekeeping Measures

7.1 Spill Prevention, Control and Countermeasure Plan

Spills and potential stormwater contamination will be controlled to reduce the chance of spills, stop the source of spills, contain and clean up spills, and dispose of materials contaminated by spills.

Spill prevention and response actions are outlined in the Spill Prevention, Control, and Countermeasure Plan (SPCC), TAB 15.

Implementation: Prior to construction activities and throughout construction.

7.2 Spills/Releases in Excess of Reportable Quantities

This permit does not provide authorization to discharge hazardous substances or oil resulting from an on-site spill. This permit does not provide relief from the federal reporting requirements of 40 CFR Part 110, 40 CFR Part 117 and 40 CFR Part 302 relating to spills or other releases of oils or hazardous substances.

For a release containing a hazardous substance or oil in an amount equal to or in excess of a reportable quantity established under either 40 CFR Part 110, 40 CFR Part 117 or 40 CFR Part 302, occurs during a 24-hour period:

• Notice will be provided to the National Response Center (800–424–8802) in accordance with the requirements of 40 CFR Part 110, 40 CFR Part 117 and 40 CFR Part 302 as soon as site staff have knowledge of the discharge; and written notice will be provided within 7 calendar days of knowledge of the release, provide a description of the release, the circumstances leading to the release, and the date of a release.

• Notify Oregon Emergency Response System at (800) 452-0311 of spills or discharges containing hazardous substance or oil.

• Measures to prevent the reoccurrence of such releases will be implemented.

7.3 Equipment/Vehicle Fueling and Maintenance Practices

On-site fueling areas will have a spill kit present, visible, and maintained. Employees and subcontractors will receive training regarding equipment/vehicle fueling and maintenance practices, including proper fueling procedures, proper use of pumps, emergency shutoff valves (training efforts documented in TAB 12).

On-site vehicles and equipment will be inspected daily for leaks, equipment damage, and other service problems.

Designate vehicle/equipment service will be marked and the areas will be located away from drainage facilities and watercourses to prevent stormwater run-on and runoff. Designated washout areas will be shown on the ESCP plan sheets (TAB 6).

[23]

Drip pans, drip cloths, or absorbent pads will be used when replacing spent fluids. All spent fluids will be collected and store in appropriate labeled containers in the proper storage areas.

Implementation: Prior to construction activities and throughout construction.

7.4 Equipment/Vehicle Washing

Equipment/vehicle washing and allowable non-stormwater will be controlled using procedures and practices include using off-site facilities; washing in designated, contained areas only;

eliminating discharges to the storm drain by infiltrating the wash water or routing to the sanitary sewer. The locations of equipment/vehicle washing areas, storm drains, tributary drainage areas, and surface waterbodies on or near the site are shown and updated on the ESCP plan sheets

(TAB 6).

7.5 Material Handling and Waste Management

Measures will be put in place and maintained to prevent the discharge of solid materials to receiving waters, except as authorized by a permit issued under the §404 permit.

• Designated trash and bulk waste-collection areas on-site (location of areas are shown and updated on plan sheets, TAB 6). Keep waste container lids closed when not in use and close lid at the end of the business day. For waste containers that do not have lids, provide a cover (e.g., tarp, plastic sheeting) to prevent exposure to precipitation.

• Litter and debris from the construction will be cleaned up on a daily basis.

• Waste-collection areas will be located away from streets, gutters, watercourses, and storm drains. Secondary containment around waste collection areas will be implemented if needed to further minimize the likelihood of contaminated discharges.

• Portable restrooms will be located away from streets, gutters, watercourses, and storm drains (location of areas are shown and updated on plan sheets, TAB 6). Secondary containment around waste collection areas will be implemented if needed to further minimize the likelihood of contaminated discharges.

• Portable restrooms will have tie-downs or stake downs in areas of high winds or susceptibility to vandalism.

• Hazardous waste-collection areas will be designated on-site (location of areas are shown and updated on plan sheets, TAB 6). Secondary containment around waste collection areas will be implemented if needed to further minimize the likelihood of contaminated discharges.

• Hazardous waste containers will be routinely inspected to ensure that all containers are labeled properly and that no leaks are present.

Implementation: Throughout construction.

[24]

7.6 Designate Concrete Washout Areas

Concrete washout areas on-site, designate specific washout areas, and design facilities to handle anticipated washout water will be installed. Washout areas will also be provided for paint and stucco operations as applicable. Washout areas will be located at least 50 yards away from storm drains and watercourses. If this is not possible, prefabricated washout containers will be used.

Alternatively, constructed washout areas may be used either by digging a pit and lining it with 10 mil plastic sheeting or creating an aboveground structure from straw bales or sandbags with a plastic liner. Designate washout areas will be shown on the erosion control plan sheets (TAB 6).

☒ Not applicable to this project

The following precautions will be implemented:

• Concrete trucks or equipment will not be washed out into storm drains, streets, gutters, uncontained areas, or any watercourses.

• Washout areas will be established prior to commencing the activity and their locations advertise with signs or delineators.

• Concrete wastewater must be directed into an impermeable-lined pit or leak-proof container sufficiently sized to avoid overflows.

• Washout structures will be routinely inspected to detect leaks or tears and to identify when materials need to be removed.

• Materials will be disposed of properly (for example, allow the water to evaporate and to recycle the hardened concrete).

• Inspections will include looking for evidence that contractors are using the washout areas and not dumping materials onto the ground or into drainage facilities. If the washout areas are not being used regularly, additional signage will be posted or the facility will be relocated to a more convenient location.

• Employees and subcontractors will receive training regarding designated washout areas, including proper handling and storage practices (training efforts documented in TAB 12).

[25]

Section 8: INSPECTIONS

8.1 Inspection Frequency

Inspections will be conducted in accordance with the following schedule(s):

Inspect all erosion and sediment control measures once every 14 days and within 24 hours of a storm event that results in discharge from the site, and/or when there is runoff from snowmelt sufficient to cause a discharge.

Inspection frequency may be reduced in accordance with the 1200-CA permit and SCR 157.14.

Inspections will be conducted by qualified personnel as required in SCR Section 157. Inspector qualifications are documented in TAB 12.

The WFL Inspection Report template will be used for all inspections. All completed Inspection Reports will be signed in accordance with the 1200-CA and SCR 107.01A.

Completed Inspection Reports are filed in TAB 9.

8.2 Corrective Actions

Corrective action is required for the following reasons and as stated in the 1200-CA:

(a) Discharges are causing an exceedance of water quality standards or there is visible turbidity in surface waters or a conveyance system leading to surface waters.

(b) An erosion and sediment control device necessary to comply with the 1200-CA was not installed or installed incorrectly.

(c) A prohibited discharge has occurred according to Section 12 of the 1200-CA.

Corrective actions will be started immediately and completed within 24 hours of discovery.

Temporary steps may be required to prevent or minimize discharge of pollutants until a permanent solution is installed; including cleaning any contaminated surfaces so that material will not discharge in subsequent storm events. If infeasible to implement corrective action within 24 hours, document reasons in the corrective action log in the ESCP and identify the schedule for repair.

All corrective actions will be signed/approved as required in the 1200-CA, SCR 107.01A, and 157.

All corrective actions will be recorded in the Corrective Action Log found in TAB 10.

Corrective actions requiring changes to the erosion and sediment control plans or ESCP narrative will be recorded on the Erosion and Sediment Control plan sheets in TAB 6 and in the ESCP narrative in TAB 1.

Executive Summary

Contaminated Media Management

Contaminated Media Environmental Management Plan Review Application

Active Chemical Treatment Systems

Active Chemical Treatment System Environmental Management Plan Review Application

Executive Summary The purpose of this Appendix is to assist 1200-CA permit registrants in complying with the requirements of Section 6 regarding DEQ review and approval of a contaminated media management plan (CMMP) or an active chemical treatment system. The permit registrant must complete an Environmental Management Plan (EMP) application, pay the review fee (See Table 70F), and submit to DEQ the required documents found on DEQ’s website and electronic reporting system when contaminated soil, contaminated groundwater or hazardous materials exist or are anticipated to be encountered during construction activities. If contaminated soil, contaminated groundwater or hazardous materials are discovered on a construction project site after construction activities are initiated, the EMP application must be submitted and approved before discharges from areas exposed to contaminated media will be authorized. The approved EMP becomes a component of the Erosion and Sediment Control Plan.

Contaminated Media Management This Section of Appendix A provides the Environmental Management Plan review application form for construction projects that will or have the potential of encountering contaminated soils, contaminated groundwater, or hazardous materials during construction activities.
