b. Noncovered Projects. All other projects within the City that have not met the threshold for covered projects shall be considered noncovered projects. Applicants for construction, demolition, and renovation projects within the City which are not covered projects shall be encouraged to divert as much project-related construction and demolition debris as possible.

No building, site development, grading, or demolition permit shall be issued for a covered project unless and until the compliance officer has approved a WMP for the project.

The WMP form shall identify (1) all C&D debris that will be generated for disposal and recycling, and (2) all disposal facilities that will receive the C&D debris.

c. Deconstruction. In preparing the WMP, applicants for building, site development, grading, or demolition permits involving the removal of all or part of an existing structure shall consider deconstruction, to the maximum extent feasible, and shall make the materials generated thereby available for salvage prior to being transported for disposal to a recycling center, transformation facility, or landfill.

a. Approval. Notwithstanding any other provision of this code, no building, site development, grading, or demolition permits shall be issued for any covered project, nor shall any demolition, construction or renovation take place on any covered project, unless and until the compliance officer has approved the WMP. The compliance officer shall only approve a WMP if he or she first determines that the WMP provides all of the information set forth in Section 5-3.603.
If the compliance officer determines that the WMP provides all of the information set forth in Section 5-3.603, then he or she shall mark the WMP "approved" and return a copy of the WMP to the applicant.
b. Nonapproval. If the compliance officer determines that the WMP is incomplete, then he or she shall either:

(§ 1 Ord. 1976, eff. 1/1/2001; § 2, Ord. 2088, eff. 7/1/2010)
§ 5-3.605. Infeasibility Exemption.¶
a. Application. If an applicant for a covered project experiences unique circumstances that the applicant believes make it infeasible to comply with the diversion requirement, the applicant may apply for an exemption at the time that he or she submits the WMP required by Section 5-3.603. Increased costs to the applicant will not be a sufficient basis for an exemption, unless such costs are extraordinary. The applicant shall indicate on the WMP the maximum rate of diversion he or she believes is feasible for each material and the specific circumstances that he or she believes make it infeasible to comply with the diversion requirement.
b. Meeting with Compliance Officer. The compliance officer shall review the information supplied by the applicant and may meet with the applicant to discuss possible ways of meeting the diversion requirement. The compliance officer may request the staff from the Central Contra Costa Solid Waste Authority attend this meeting or may require the applicant to request a separate meeting with Central Contra Costa Solid Waste Authority staff. Based on the information supplied by the applicant and, if applicable, Central Contra Costa Solid Waste Authority staff, the compliance officer shall determine whether it is possible for the applicant to meet the diversion requirement.
c. Granting of Exemption. If the compliance officer determines that it is infeasible for the applicant to meet the diversion requirement due to unique circumstances, he or she shall determine the maximum feasible diversion rate for each material and shall indicate this rate on the WMP submitted by the applicant. The compliance officer shall return a copy of the WMP to the applicant marked "approved for infeasible exemption."
d. Denial of Exemption. If the compliance officer determines that it is possible for the applicant to meet the diversion requirement, he or she shall so inform the applicant in writing. The applicant shall have 30 days to resubmit a WMP form in full compliance with Section 5-3.603. If the applicant fails to resubmit the WMP, or if the resubmitted WMP does not comply with Section 5-3.603, the compliance officer shall deny the WMP and return the WMP to the applicant marked "denied," including a statement of reasons.
(§ 2, Ord. 1976, eff. 1/1/2001; § 2, Ord. 2088, eff. 7/1/2010)
§ 5-3.606. Submission of Waste Management Report (WMR).¶
a. WMR Form. Within thirty (30) days after the completion of any covered project, the permit holder shall submit a WMR to the compliance officer that proves that the covered project has met the diversion requirement. This WMR shall include all of the following:
Receipts from each certified C&D recovery facility and other disposal facility for each type of material collected or received that show the actual weight or volume of material; and
A summary of the total weights of each material collected or received from the receipts in subsection (a)(1) of this section. Receipts based upon volume shall be converted to weight using City-approved conversion factors; and
Any additional information that the permit holder believes is relevant to determining his or her efforts to comply in good faith with this article.
b. Weighing of Wastes. The permit holder shall make reasonable efforts to ensure that all C&D debris diverted or landfilled are measured and recorded using the most accurate method of measurement available. To the extent practical, all C&D debris shall be weighed by measurement on scales. Such scales shall be in compliance with all regulatory requirements for accuracy and maintenance. For C&D debris for which weighing is not practical due to small size or other considerations, a volumetric measurement shall be used. For conversion of volumetric measurements to weight, the permit holder shall use the standardized conversion factors approved by the City for this purpose.
(§ 2, Ord. 2088, eff. 7/1/2010)
§ 5-3.607. Compliance with WMR.¶
The compliance officer shall review the information submitted under Section 5-3.606(a) and determine whether the permit holder has complied with the diversion requirement, as follows:
a. Full Compliance. If the compliance officer determines that the permit holder has fully complied with the diversion requirement applicable to the project, he or she shall indicate such compliance on the WMR.
b. Good Faith Effort to Comply. If the compliance officer determines that the diversion requirement has not been achieved, he or she shall determine on a case-by-case basis whether the permit holder has made a good faith effort to comply with this article. In making this determination, the compliance officer shall consider the availability of markets for the C&D debris landfilled, the size of the project, and the documented efforts of the permit holder to divert C&D debris. If the compliance officer determines that the permit holder has made a good faith effort to comply with this article, he or she shall so indicate on the WMR.
c. Noncompliance. If the compliance officer determines that the permit holder has not made a good faith effort to comply with this article, or if the permit holder fails to submit the documentation required by Section 5-3.606(a) within the required time period, then the permit holder shall be in violation of this article and be liable for a civil penalty, in addition to any other remedy provided by this article. No certificates of occupancy or other permits or approvals relating to the project site shall be issued by the City until the civil penalty has been paid in full.

Any person who violates any provision of this article, including but not limited to noncompliance with a WMR, shall be liable to the City for a civil penalty of one thousand dollars ($1,000.00) or one percent (1%) of the total cost of the project, whichever is greater. The compliance officer may, in his or her sole discretion, reduce the amount of the civil penalty in the event of mitigating circumstances.
