The comment period ended on August 26, 2020.

Determination

As lead agency for this proposal, the City of Tieton, after reviewing a completed environmental checklist and other information on file with the lead agency, has determined that the project will not have a probable significant adverse impact on the environment, and an environmental impact statement will not be required, provided the measures listed below are used to mitigate potential adverse impacts. The information relied upon in reaching this determination is available to the public upon request from the City of Tieton.

Identified Environmental Impacts and Mitigation Measures:

No environmental impacts have been identified which are not already mitigated under current City of Tieton Codes, other required permits and identified mitigations.

Yakima Regional Clean Air Agency:

1. The applicant shall file a Dust Control Plan with the Yakima Regional Clean Air Agency, prior to construction.

2. Burning is prohibited at all times within the City of Tieton.

Washington State Department of Ecology:

3. Based upon the historical agricultural use of this land, there is a possibility the soil contains residual concentrations of pesticides. Ecology recommends that the soils be sampled and analyzed for lead and arsenic, and for organochlorine pesticides. If these contaminants are found at concentrations above the Model Toxics Control Act cleanup levels Ecology recommends that potential buyers be notified of their occurance. Per recommendation from Ecology the applicant shall sample the soil and analyzed for lead and arsenic and organochlorine pesticides and if found cleanup/notification measures be accomplished per Ecology requirements.

4. The NPDES Construction Stormwater General Permit is recommended. Obtaining a permit may take 38-60 days. The permit requires that a Stormwater Pollution Prevention Plan (Erosion Sediment Control Plan) shall be prepared and implemented for all permitted construction sites. These control meaures must be able to prevent soil from being carried into surface water and storm drains by stormwater runoff. Permit coverage and erosion control measures must be in place prior to any clearing, grading, or construction. In the event that an unpermitted Stormwater discharge does occur off-site, it is a violation of Chapter 90.48 RCW, Water Pollution Control and is subject to enforcement action.

More information on the stormwater program may be found on Ecology’s stormwater website at: http://www.ecy.wa.gov/programs/wq/stormwater/construction/. Please submit an application or contact Lloyd Stevens Jr. at the Dept. of Ecology, 509-574-3991 or email lloyd.stevensjr@ecy.wa.gov, with questions about this permit.

City of Tieton:

5. All Stormwater shall be retained on-site. Applicant shall provide engineered drawings acceptable to the City of Tieton, showing how and where Stormwater will be retained. Detention/Retention facilities shall be designed in accordance with the Eastern Washington Stormwater Manual.

6. City Engineering consultant (HLA) plan review comment letter dated September 18, 2020 number 5 requires the addition of stop signs, including for traffic entering Summitview Road from Baughman Street. Additionally, in a follow up email comment dated September 30, 2020 noted that, Although the City Engineer believes a stop sign to be sufficient given the amount of expected traffic, the sight distance, and the speed limit, recommends the developer contract with a licensed traffic engineer to have a traffic impact analysis performed at the proposed intersection to verify additional measures of traffic control are not necessary. Based on the City Engineer the applicant shall provide a traffic impact analysis to determine no additional traffic control is needed. Based on the traffic impact analysis and review by the City Engineer finds additional measures are needed they shall be provided as determined by the City Engineer.
