Today, the proposed silica rule (reducing the occupational permissible exposure limit) will head to its final stage of review at the Office of Management and Budget and will likely become final during the early party of 2016—a long anticipated rule that is twelve years in the making.
We agree permissible exposure limits implemented in the early 1970s should be reviewed and revised, however, relying on outdated data from over a decade ago should not be the standard we expect from our government when issuing new regulations. The standard should be higher. Manufacturers have been concerned with the length of time this rule has taken to move forward—from submission of public comments to the final rule stage will be more than two years. The NAM first submitted comments in February 2014 and then testified at a public hearing in March 2014 and submitted its final brief before the record closed in August 2014.
