Requirements for all projects

All funded projects must adhere to:

Funding Guidelines for the fiscal year of the award (see below)
Administrative Requirements for Ecology Grant and Loans (Yellow Book)
Terms and conditions of your funding agreement

If your project received Clean Water State Revolving Funds (CWSRF) Loan, there are additional requirements.

Other requirements

Cultural resources review

You must complete Ecology’s cultural resource requirements before any geotechnical work, acquisition, site prep work, or construction takes place.
To initiate cultural resources review, you will complete and submit an Ecology Cultural Resources Review Form and Inadvertent Discovery Plan to the Ecology Project Manager.
For more information and links to these forms, visit the Environmental and cultural resources review page and Appendix N of the WQC Funding Guidelines.

Environmental review

Most stormwater projects require State Environmental Policy Act (SEPA).

You, as the Recipient, are the lead agency and will determine if SEPA is required.
Upload the SEPA Checklist and notify the Ecology Project Manager when the official comment period begins.
For more information, visit the Environmental and cultural resources review page.

Procurement, purchasing, and contracts

State procurement requirements apply to all projects. You can find further information in the Yellow Book (pg. 48).

Contract clauses and specifications inserts for state funded projects:

Professional service contracts
- Standard Contract Clauses
Construction contracts
- Stormwater Grant Program Bid Specification Clause
- Stormwater Grant Program Bid Insert
CWSRF Loan projects have additional requirements.

GIS guidance

We require a GIS deliverable for facility projects. The GIS data informs project management and implementation and aids in understanding project effectiveness.
Accepted formats include web maps, map services, feature services, shapefiles, and file geodatabase files. Use the Stormwater Facility GIS file geodatabase templates to format the best management pracitce (BMP) and contributing area data.
See Stormwater Deliverables Guidance (Section 2.7) for more information.

Project close out

You should begin preparing for agreement close out at least 90 days before the agreement expiration date.
An Outcomes Summary and a Recipient Close Out Report in EAGL must be submitted for all projects. Find your project type below for templates and directions on how to fill out these forms.
Final PRPRs are due within 30 days after the project expiration date.

Activity project resources

EMP guidance can be found in the Stormwater Deliverables Guidance (Section 3.1).
Ecology must approve the make and model before equipment purchases of sweepers or vactor trucks.
For any equipment purchase over $5,000, you must fill out an Equipment Purchase Report in EAGL. Directions can be found in the EAGL User Manual (Section 13).
Close out templates:
- Activity Projects Recipient Close Out Report Template in EAGL
- Activity Projects Outcomes Summary Template

Facility project resources

For bid specification and inserts, see the procurement, purchasing, and contracts section.
Projects must adhere to the funding source recognition signage requirements and give credit to all funding sources (i.e. EPA and Ecology).
A Stormwater Construction Completion Form is required when construction is complete. The professional engineer signs this form to indicate that the contractor completed the project in accordance with the Ecology-accepted plans and specifications.
See the Stormwater Deliverables Guidance (Section 2) for more information.
Close out templates:
- Facility Projects Recipient Close Out Report Template
