California Code, Business and Professions Code - BPC § 13652

(a) Any person who intentionally violates any provision of this chapter or any regulation promulgated pursuant thereto is guilty of an infraction, and, upon conviction, shall be punished by a fine not to exceed fifty dollars ($50) for each day that the person violates the provision or regulation.

(b) The failure of an owner or manager of a service station to have adequate water and air facilities available for use by the public, or to provide permanent public restrooms for use by its customers, as required by subdivision (b) of Section 13651, for five consecutive working days, constitutes a rebuttable presumption affecting the burden of proof that the owner or manager has intentionally violated this chapter.  This subdivision does not apply to restrooms rendered inoperable as a result of vandalism or plumbing problems that may not be readily repaired.

(c) Notwithstanding any other provision of this chapter, no person shall be guilty of the infraction specified in subdivision (a) if that person, within seven days after receiving notification from the city attorney, district attorney, or Attorney General of any violation of this chapter, makes whatever changes are necessary to comply with the requirements of this chapter.
