Water Quality Monitoring Plan – Mechanical and Hydraulic Dredging Keystone Harbor Maintenance Dredging and Disposal

19 March 2020

1. Introduction The Keystone Harbor Federal Navigation Maintenance Dredging and Disposal project requires the following water quality monitoring parameters pursuant to Water Quality Certification (WQC) #18080/Public Notice of Application CENWS-PMP-20-01 Keystone Harbor, Whidbey Island, WA for State of Washington 401 Water Quality Certification and Coastal Zone Management Act Consistency (date) and WAC 173-201A-210.

2. Mechanical Dredging:

Keystone Harbor will be dredged at night to avoid to conflicts with the Washington State Ferry service. During the dredging activities, at night, scow(s)/barge(s) will be off-loaded to a temporary staging area/stock pile or trucks. Placement of material on trucks or stockpiled upland will also occur at night during dredging. Material will be moved and graded to the placement site during daylight hours. The material is coarse grained (sand/gravel) and will contain little water when it’s placed on land so impacts to water quality are not expected.

Turbidity applicable criteria:

o Turbidity should not exceed 5 NTU over background or 10% over background if background is greater than 50 NTU, or a visible plume at the point of compliance.

Constituents monitored:

o Turbidity monitoring during the channel dredging is not possible since dredging will occur at night to avoid interference with the Washington State Ferry service.

o Turbidity monitoring at the placement site is not necessary. Since the material will be placed on land or in trucks, will have little to no water in it, and is course grained material, impacts to water quality in the nearby water bodies are not expected.

3. Hydraulic Dredging:

Keystone Harbor will be dredged at night to avoid to conflicts with the Washington State Ferry service. Placement of material via pipeline will also occur at night during dredging. The material is coarse grained (sand/gravel) so impacts to water quality are not expected.

Turbidity applicable criteria:

o Turbidity should not exceed 5 NTU over background or 10% over background if background is greater than 50 NTU, or a visible plume at the point of compliance.

Constituents monitored:

o Turbidity monitoring during the channel dredging is not possible since dredging will occur at night to avoid interference with the Washington State Ferry service.

o Visual monitoring at the placement site will occur only if light conditions allow. This would likely occur at dawn during summer months after a night of dredging, but prior to ferry service commencement. The contractor will observe if there is a turbidity plume from shore and at the Point of Compliance, which is 150 feet down current from the placement.

Frequency of Monitoring:

The contractor shall monitor for turbidity visually daily after placement activities at dawn, if it occurs prior to the ferry service commencement.

The contractor shall continue to monitor and record (written) daily visual turbidity monitoring at the disposal site during every disposal event every day at dawn (only if there is daylight prior to the ferry service commencement). At any point, including observations outside normal monitoring, if visual monitoring indicates a turbidity plume, the exceedance protocol listed below shall be followed.

Sampling Approach:

The contractor shall visually observe turbidity at dawn (if prior to ferry service commencement) and record the findings according to the frequency.

The contractor shall visually observe turbidity within the placement area and record the findings of every disposal action at dawn, if it occurs prior to ferry service commencement.

Monitoring Locations:

The area of mixing point of compliance for turbidity is 150 feet down-current from the point of placement, and thus will move as disposal progresses.

Exceedances and Exceedance Protocol If a visual turbidity plume is present at or beyond 150 feet from the dredging activity and/or within the disposal area for a disposal action, that sample is recorded as an EXCEEDANCE.

o The Contractor shall immediately verify that dredging and disposal BMPs are already implemented. If not, immediately implement appropriate BMPs.

o The Contractor shall notify the Corps by telephone as soon as is practicable, but within 30 minutes after there has been a visual exceedance.

o The Corps will notify Washington Department of Ecology (WA Ecology) of the situation as soon as is practicable, but within 24 hrs of the visual exceedance.

o The Corps will work with the Contractor to evaluate and identify conditions or actions that may be contributing to increased turbidity.

During the notification and evaluation period, the Contractor will monitor and record the turbidity plume every 30 minutes until it is no longer visible.

If the visual turbidity is caused by the dredging and/or disposal actions, those actions will be immediately addressed and corrected.

If compliance cannot be achieved, the Contracting Officer may issue a stop work order until corrections are completed and/or plume has dissipated.

Once compliance has again been achieved, the Contracting Officer will order the Contractor to resume dredging.

The Corps will provide monitoring data to WA Ecology and notify WA Ecology that dredging has resumed.

4. Reporting:

The Corps will report exceedances, including potential causes and BMPs to prevent reoccurrence, and/or dredging shut downs to WA Ecology by telephone and email as soon as is practicable, but within 24 hrs.

The contractor shall document any dredging shut downs with an Incident Report, which will be transmitted to the Corp by email and through the QCS/RMS system within 24 hours of the exceedance.

The Incident Report shall document all exceedances and will include the date, time, location, activity, turbidity data collected, name of person collecting the data, names of persons notified of the exceedance, photographs if taken, and summary of how the exceedance was resolved following the above protocol.

The Incident Report shall be sent to WA Ecology within five (5) days of the exceedance, per the 401 Certification.

Per the 401 WQC, weekly turbidity (visual or measured) reporting will be sent to WA Ecology.

Within 60 days of termination of the dredging and disposal activities, the Corps will submit a summary report of the turbidity results to WA Ecology.

5. Responsibility and Communication Plan:

The Corps will oversee turbidity monitoring conducted by the contractor.

The Corps will be responsible for coordinating with WA Ecology and submitting the Turbidity

Monitoring Reports and data provided by the contractor.

The Corps will notify WA Ecology within 24 hours if an exceedance occurs.

The Corps will coordinate with the dredging contractor.

The contractor shall provide Turbidity Monitoring Report and data to the Corps, as directed.

The contractor shall notify the Corps within 30 minutes of a confirmed exceedance and follow required notifications per the exceedance protocols.

The contractor POC will be provided in the Contractor Water Quality Monitoring Plan.

The Corps Points of Contact for turbidity monitoring will be Michael Suh, Project Manager (206-

764-6671), and Chemine Jackels, Environmental Coordinator (206-764-3646).

The WA Ecology Point of Contact is Laura Inouye, (360-407-6165).

Official reporting of any incidents are to be sent to both the WA Ecology Point of Contact AND to the fednotification@ecy.wa.gov inbox.
