Proposed – and very controversial – plans to tighten regulations governing emissions from America’s power plants will not become final until sometime mid-summer, the Environmental Protection Agency announced yesterday.

Your Home Builders Association submitted more than a hundred pages of comments on the proposal in December, and the agency had planned to finalize its regulations by June 15, 2015.

While the sweeping regulations target power plants, they would have repercussions for home builders, who could be targeted with much tighter building code requirements if the draft rule becomes final.

However, as the National Association of Home Builders said in its comments, stricter energy codes would affect only new construction, not the millions of older homes not built to today’s higher standards, and EPA has no authority over building codes in the first place.

In addition, no agency or regulatory body can control how much electrical power a home owner decides to use once the building is occupied.
