However, the Alameda Creek Alliance viewed the records on file at the RegionalWater Quality Control Board and noted many self-reported violations of water quality permits forRMC Pacific Materials, including exceedances of allowed turbidity levels, and non-reportingviolations. Mission Valley Rock Company had not filed self-monitoring reports for the past fiveyears.How can the SFPUC be considering expansion of quarrying leases, let alone continuation ofexisting leases to leaseholders which violate the terms of their permits and the terms of theirleases (which require compliance with all permits)?” (Alameda Creek Alliance)Response: It is unclear from the above comment which RMC Pacific Materials permits thecommentor is referring to.
