AGC prefers the present approach, which is managed under EPA and state permitting programs. It allows firms to use best practices for erosion and sediment control to work toward a general goal that addresses conditions for different sites, Pilconis says.

If firms do not meet the goal, they can add additional controls.

Nick Goldstein, American Road and Transportation Builders Association as vice president of environmental and regulatory affairs, says a one-size-fits-all approach “isn't appropriate.”

He says EPA typically looks at solutions that are appropriate for “big box stores or condominium developments” but not transportation projects, which have different site conditions and linear configurations.

Industry officials say the impact of a numeric limit would be significant.

“It will impact all phases of construction and the majority of our membership,” Pilconis says.
