This warning pertains to the California Safe Drinking Water and Toxic Enforcement Act of 1986 commonly referred to as Proposition 65 which requires warnings about chemicals known to cause cancer or birth defects or other reproductive harm. For more than thirty years this law has required businesses selling products in the State of California that may expose persons to chemicals known to the State of California to cause cancer and birth defects or other reproductive harm to provide special warnings. The Proposition 65 regulations have recently changed and effective August 30, 2018, new requirements apply to the content and location of certain Proposition 65 warnings. In response to these changes, Schiller Grounds Care, Inc. is providing the warning you see on the product web page you viewed prior to linking to this explanation. The company has the same warning on the product associated with that product web page. The regulatory agency in the State of California responsible for Proposition 65 has made additional information about Proposition 65 available on its web page: https://oehha.ca.gov/propostion-65.
The company is also party to a 1995 consent decree entered into together with many other manufacturers of covered products (as defined in the consent decree) and for those products the company has, in addition to the warning referred to above, also included the Proposition 65 warning mandated by the consent decree in the owner’s/operator’s manual for the covered product.
