(a) The amount of residual in the C&D debris and type A inert debris shall be less than 40% of the amount of such material by weight. The residual amount is calculated on a monthly basis. Facilities which do not meet the 40% residual requirement of this subsection shall obtain a Full Permit and shall comply with the requirements applicable to a Large Volume CDI Debris Processing Facility. If the EA determines that a Medium Volume CDI Debris Processing Facility has exhibited a pattern and practice of failing to comply with the provisions of this subsection, the EA shall take appropriate enforcement action.

(b) CDI debris stored for more than 15 days that has not been processed and sorted for resale or reuse shall be deemed to have been unlawfully disposed, and therefore subject to enforcement action including the use of a Notice and Order as provided in section 18304.

(c) CDI debris that has been processed and sorted for resale or reuse, but remains stored on site for more than one year, shall be deemed to have been unlawfully disposed, and therefore subject to enforcement action including the use of a Notice and Order as provided in section 18304.

(d) The maximum amount of material that may be stored on the site, including unprocessed material, material that is being processed, and material that has been processed, is that amount which is the product of 30 days multiplied by the maximum amount of incoming material permitted per day.

(e) Storage time limits may be extended in accordance with sections 17384(a) (Land Use Entitlement), 17384(b) (Storage Plan), and 17384(c) (Financial Assurances) of this Article.

(f) Residual material shall be removed from the site within 48 hours or at an alternate frequency approved by the EA.

(g) Each operator of a medium volume CDI processing facility shall file with the EA, together with its application for a Registration Permit, a CDI Processing Facility Plan (as more fully described in Article 3.2, section 18223 of this Chapter). The information contained in the Plan shall be reviewed by the EA to determine whether it is complete and correct as defined in CCR, Title 14, Chapter 5. Article 3.0, section 18101.

(h) Medium volume CDI debris processing facilities shall be inspected monthly by the EA in accordance with PRC section 43218. To the greatest extent possible, all inspections shall be unannounced and shall be conducted at irregular intervals.

(i) Where the public may have access to them, the debris piles and other piles of materials on site must be stable and otherwise configured so as to protect the public health and safety.

(j) C&D Mulch that is not compostable material produced at a medium volume CDI processing operation must meet all requirements of a medium volume chipping and grinding operation, including the storage limits.

(k) If a medium volume CDI processing facility exceeds any combination of the following limitations, which are more fully described in this Section 17383.5, three (3) or more times within any two (2) year period which the EA determines constitutes a violation of this Article, then the facility no longer qualifies for a Registration Permit under this section. Upon the third such violation, the EA shall notify the operator in writing that the facility no longer qualifies for a Registration Permit, and the operator must within 30 days apply for a Full Permit as if it were a large volume CDI processing facility pursuant to Section 17383.6. In addition, the EA shall issue a cease and desist order pursuant to Section 18304 directing, among other things, that the operator immediately cease accepting material at the site until the operator has demonstrated to the EA that it has corrected the violation and eliminated the cause of the violation. The limitations to which this subdivision applies are:

(l) Each operator shall determine the weight of all material received at the facility for handling and shall maintain records of the weight of materials in accord with State Minimum Standards. Weight shall be determined by the use of scales which may be located at the facility or off-site.

(m) Each operator shall maintain records in accordance with Title 14, California Code of Regulations, Division 7, Chapter 9, Article 9.25, Section 18815.1 et seq. The records shall be available for inspections as authorized by that article during normal business hours and retained in the operating record near the site or in an alternative location approved by the Local Enforcement Agency.
