The San Rafael Rock Quarry (SRRQ) extended the date of its approved Conforming Amended Reclamation Plan of 2010 (CARP10) from December 31, 2024 to December 31, 2044 to complete reclamation activities. Early phases of reclamation began in 2018. The amendment to CARP10 changed the currently approved 12-year schedule to finish reclamation phasing to a 26-year schedule, essentially doubling the amount of time needed to finish reclamation at the SRRQ. RCH conducted an air emissions inventory, health risk assessment, and noise analysis associated with extending the time for reclamation anticipated completion from 2024 to 2044, a period of 20 years.
