{Bluefield, West Virginia}...State regulators have denied Bluefield Gas' request to raise rates by 6.89%. The Public Service Commission says in an order released this week that professional account expenses submitted by the company were in dispute. The utility was ordered to coordinate its tax year and annual report year. Bluefield Mayor Linda Whalen says Bluefield Gas, which serves about 3,600 customers, had received approval to raise rates eight out of the past 10 years, and any increase would be an additional burden.
