Cal. Health and Safety Code § 118160

(a) Prior to issuing or renewing a permit for an offsite medical waste treatment facility, the department shall review the compliance history of the applicant, under any local, state, or federal law or regulation governing the control of medical waste or pollution. (b) The department shall, pursuant to this section, deny a permit, or specify additional permit conditions, to ensure compliance with applicable regulations, if the department determines that in the three-year period preceding the date of application the applicant has violated laws or regulations identified in subdivision (a) at a facility owned or operated by the applicant, and the violations demonstrate a recurring pattern of noncompliance or pose, or have posed, a significant risk to public health and safety or to the environment. (c) In making the determination of whether to deny a permit or to specify additional permit conditions, the department shall take both of the following into consideration: (1) Whether a permit denial or permit condition is appropriate or necessary given the severity of the violation. (2) Whether the violation has been corrected in a timely fashion.
