Agency: Bay Area Air Quality Management District (BAAQMD)
A regional dispatcher will answer the phone. Tell them you are reporting excess emissions coming from the Lehigh Southwest
Cement Plant on Stevens Creek Blvd in Santa Clara County. BAAQMD will send an inspector to the facility.
You can make an anonymous report, but if you give your name and phone number the BAAQMD inspector will call you back with his or her findings.
The cement plant and quarry should have very little, if any visible emissions, so if you see clouds of dust, or large plums of emissions from the central stake or elsewhere on the property please call the hotline and if you can, take a picture.
Agency: San Francisco Regional Water Quality Control Board
Permanente Creek traverses the Lehigh property, running very close to the quarry then down through Rancho San Antonio Park ( the bridges into the park from the parking lots cross Permanente Creek). It then heads east through Los Altos under Hwy 280 roughly following Miramonte Rd. through Mountain View to the Bay. Check the water quality in the creek as you cross the bridges into Rancho San Antonio. If there hasn’t been any heavy rain in a couple weeks and the water is turbid or milky like the picture opposite it maybe an indication that something up stream is wrong and should be reported at the number above.
