Recent exceedances of the regulatory compliance criteria have led to DEM, in collaboration with EPA, to take compliance action against the site operator. DEM and the EPA are seeking further improvements to stormwater management at the quarry over the next 12 months.

Hanson is required to monitor (by an independent expert) the quality of any water leaving the site against the compliance criteria which sets the maximum permissible sediment level in water leaving the site.

DEM and the EPA will continue to actively regulate the site, including any proposed improvements to surface water management. As with all quarry operations, the department supports direct engagement between operators and the communities they operate in.
