Central Receiving Station Tier 2

Stormwater Corrective Action Response

Waste Management Division

OVERVIEW

Lane County Waste Management is seeking a qualified firm to perform a Tier 2 Corrective Action Response for its 1200‐z Stormwater Permit at the Glenwood Central Receiving Station (CRS) located at 3100 East 17th Avenue Eugene, OR 97403. CRS has exceeded the geometric mean of Copper and Zinc at outfall 004 and has also exceeded the geometric mean of Copper and Lead at outfall 008, triggering the requirement for a Tier 2 Corrective Action Response.

The selected firm will be responsible for completing the report, securing DEQ approval, and implementing corrective actions or mass reduction measures within the required deadlines.

According to the County’s 1200z permit, Tier 2 Corrective Action and Reporting must include:

1. A SWPCP appendix including: Tier 2 report, a Tier 2 mass reduction waiver request, or a Tier 2 background waiver request as described in Oregon’s current 1200‐z permit.

2. Properly apply and size approved Tier 2 corrective action responses and mass reduction measures to all substantially similar discharge points.

3. The Tier 2 report must include a proposal for active or passive treatment. This may include a combination of source removal, control and treatment measures, with the goal of achieving the benchmarks in this permit. The report must include the rationale for the selection of the control and treatment measures, the projected reduction of pollutant concentrations and the schedule for implementing these measures.

4. An Oregon registered PE must design and stamp the portion of the SWPCP that addresses these controls.

5. Additional information on the requirements are listed in DEQ’s Tier 2 Revised Stormwater Pollution Control Plan Checklist Instructions, attached to this RFQ.

Deadlines:

1. Proposed Tier 2 corrective action response to DEQ no later than December 31, 2022 (six months after the end of the full reporting year that triggered Tier 2), unless DEQ approves a later date.

2. DEQ will notify the permit registrant within 60 calendar days of receipt of the Tier 2 Report whether the proposed Tier 2 corrective action is approved or denied.

3. Tier 2 corrective action(s) or mass reduction measures(S) must be installed and implemented no later than September 30 (a year and nine months after the Tier 2 proposal corrective action response submittal deadline) unless DEQ or agent approved a later date. If the permit registrant changes the specifics of the corrective actions before implementation, revisions must be submitted and approved by DEQ before implementation. Corrective action revisions do not change the Tier 2 implementation deadline.

4. No later than 30 calendar days from implementing Tier 2 corrective actions or mass reduction measures, the permit registrant must inform DEQ of the date of completion. This notification requirement also applies to facilities with an implementation deadline established in the previous permit.

5. No later than 30 calendar days from implementing all Tier 2 corrective actions or mass reduction measures, the permit registrant must submit all new and modified control measures and any associated changes to monitoring or discharge points within a SWPCP revision.

This request is to provide all material, plans, labor and equipment to accomplish this work. All work shall be completed in compliance with all federal, state and local requirements. The County will issue a contract to the selected firm using a standard Lane County contract form, a copy of which is available upon request. The term of the resulting contract will extend through completion and acceptance of the implementation of the corrective actions and reduction measures.

Monitoring point, Parameter and Corresponding Geometric Mean Exceedance

• Please indicate the monitoring point, as identified on the Site Plan in your Stormwater Pollution Control Plan and also on your Discharge Monitoring Report.

• Please indicate the parameter, units and geometric mean associated with each monitoring point exceedance.

• Please note, if you are not sampling all of your stormwater discharge points and your pollution control plan has identified substantially similar effluent based on a site analysis and/or monitoring, then you must install the same treatment on those representative discharge points.

Once implemented, you must sample substantially similar discharge points for the parameters that triggered Tier 2.

Projected Reduction of Pollutant Concentration Treated Please provide the projected percent reduction in concentration for the proposed treatment measure associated with the corresponding geometric mean exceedance. Regardless if a facility is proposing one treatment system to address more than one geometric mean exceedance or multiple treatment measures with the goal of reaching a single benchmark, please list the percent reduction for each parameter. The projected percent reduction should reduce the pollutant discharged to or below the benchmark.

Percent of Design Storm Volume Infiltrated Please provide the calculated percent of the design storm that will be infiltrated for the drainage basin being addressed, if applicable. Facilities choosing to submit a Tier 2 Mass Reduction Waiver request need to evaluate their site and show how the remaining mass load of pollutants discharged are at or below the mass equivalent of the statewide benchmarks. In addition, provide the information requested in the Tier 2 Waiver table. This calculation may result in discharge above the benchmark values. The revised Stormwater Pollution Control Plan must provide data and analysis to support this mass load analysis determination, including the detailed description of the measure(s).

Design Storm Criteria

Precipitation Data

1. Determine the 2-year, 24-hour rainfall depth for the facility using latitude and longitude; this information can be found here: http://www.nws.noaa.gov/ohd/hdsc/noaaatlas2.htm

2. Determine the Water Quality Design Storm amount by locating your facility’s zone on the Oregon Department of Transportation’s Water Quality Design Storm Factor map, attached below.

Multiply the 2-year, 24-hour storm rainfall depth from Step #1 by the appropriate factor (50%, 67%, or 75%). The majority of the state will use 50% of the 2-year, 24-hour rainfall depth. For example, if the 2-year, 24-hour rainfall depth according to NOAA is 3.0 inches, and the facility is in Zone 6 on the map below, 3.0 x 50% = 1.5 inches. The Design Storm amount is 1.5 inches.

3. Design to a minimum storm size of 0.7 inches in 24- hours in order to capture the first flush of industrial pollutants, even if the calculation from Step #2 is fewer than 0.7 inches.

4. Compare the calculated Water Quality Design Storm to the facility’s local jurisdiction’s water quality design storm and use whichever is more stringent.

Please simply indicate the page numbers of the stamped plan or waiver for the following items:

Rationale for the Selection of the Measures The permits require the revised Stormwater Pollution Control Plan include data and analysis to support the selection of each treatment best management practice or infiltration measure.

Schedule for Implementing Measure Please include the expected implementation schedule for the proposed measures. The permit deadlines include:

• Submit a proposed Tier 2 corrective action response to DEQ or agent no later than December 31

(six months after the end of the full reporting year that triggered Tier 2) unless DEQ or agent approved a later date.

• Complete construction and implement treatment or mass reduction measures no later than Sept 30 (a year and nine months after the Tier 2 proposal corrective action response submittal deadline) unless DEQ or agent approved a later date.

Cost of proposed Tier 2 Response

Created by: Krista Ratliff Last updated: 7/21

As part of the rationale in the selection of the measures, the facility must consider cost. In order to meet the implementation schedule, it is highly recommended that all proprietary, capital investment, permitting, operational and maintenance, as well as energy costs are evaluated.

Treatment System Schematic Please include design and site location information for proposed treatment measures. Registrants are responsible for meeting water quality standards, including assurance that any chemical treatment is nontoxic to aquatic organisms. Any state approved program may be cited, such as Technologies Assessment Protocol - Ecology (TAPE).

Operation and Maintenance Schedule All Tier 2 responses will require some maintenance overtime to optimize pollutant removal and manage break-through. Break-through happens when media is clogged or no longer treats the stormwater pollutants. Although each facility maintenance schedule will vary based on loading, this is an important component of the revised Stormwater Pollution Control Plan. Schedule A.10.b.vii and Schedule A.10.e outline maintenance and repairs which must be recorded and available for review upon request of DEQ, agents or a local municipality. The revised Plan must include a projected maintenance schedule. DEQ recognizes this may vary once installation is complete. Please ensure any Plan revisions related to operations of control measures are submitted to DEQ or agents within 30 days calendar days after the change.
