Here's a great write up on the ruling:
New EPA Lead Paint Rules Increase Renovation Costs —Professional tool reviews for the average Joe
And a portion of it,
"These new EPA rules are going to apply to buildings built prior to 1978 and will affect jobs ranging from full-blown renovations, down to simple window replacements and paint jobs. If the job covers more than 6 square feet - it's now regulated. Members of the National Association of Homebuilders (NAHB) estimate the added regulations will increase project costs anywhere from $500 to $1,500 for projects costing over $5,000. Of course, the EPA disagrees, feeling that these regulations will yield only a modest $35 increase per job.
And we wonder why the government gets into debt."
