This notice of complete application applies only to the permits identified above. It is your responsibility to apply for and obtain all necessary permits issued by other agencies. Please arrange to have a public notice board for this project manufactured and installed on site within 14 days (by August 12, 2016).

Will the proposal require any new or improvements to existing roads or streets, or improvements to existing roads or streets, not including driveways? If so, generally describe (indicate whether public or private). The proposal will not require any new or improvements to existing roads or streets. e. Will the project or proposal use (or occur in the immediate vicinity of) water, rail, or air transportation? If so, generally describe. The project site is located in an active BNSF Railway Hub Yard, and will occur in the immediate vicinity of rail transportation. Approximately 100 linear feet of new stormwater conveyance pipe will be installed underneath the railroad tracks in the Central Drainage Area. f. How many vehicular trips per day would be generated by the completed project? If known, indicate when peak volumes would occur and what percentage of the volume would be trucks (such as commercial and nonpassenger vehicles). What data or transportation models were used to make these estimates? The completed project will not generate daily trips. Only monthly or quarterly vehicular trips (by one vehicle) will be made to the project site for maintenance of the stormwater treatment system. The system will largely be operated remotely.

Will the proposal interfere with, affect or be affected by the movement of agricultural and forest products on roads or streets in the area? If so, generally describe. No, the proposal will not interfere with, affect or be affected by the movement of agricultural and forest products on roads or streets in the area. h. Proposed measures to reduce or control transportation impacts, if any: No transportation impacts would occur and no measures are proposed. 15. Public Services a. Would the project result in an increased need for public services (for example: fire protection, police protection, public transit, health care, schools, other)? If so, generally describe. No, the proposed stormwater treatment systems would not result in an increased need for public services. b. Proposed measures to reduce or control direct impacts on public services, if any. No impacts to public services are anticipated and no mitigation measures are proposed. 16. Utilities a. Circle utilities currently available at the site: electricity, natural gas, water, refuse service, telephone, sanitary sewer, septic system other: b. Describe the utilities that are proposed for the project, the utility providing the service, and the general construction activities on the site or in the immediate vicinity which might be needed. The project includes improvements to the site's electrical system. The stormwater treatment system would operate with electric pumps and electronic monitoring systems.
