The path of the proposed transmission line runs across land owned by the Tucson Airport Authority and a land investment company, and past a small subdivision on the east side. Existing power lines run along the east side of South Swan.

TEP says it worked with TAA and the landowners on the preferred route approved by the state line-siting committee, though Pima County objected to part of the northern route favored by the airport on grounds it could interfere with future plans for a connecting highway to I-10 as part of the Sonoran Corridor economic-development plan.

TEP spokesman Joe Barrios said the company received little feedback from residents in the area and no significant opposition.

The utility said it sent notices to more than 16,000 residents in the larger region of the project and after two public meetings it received 21 comments.

TEP said 10 residents stated a route preference and about a third cited health concerns related to radiation from the transmission lines, with no overwhelming opposition or support for any route alternatives.
