(b) For the purposes of recovering the department’s costs pursuant to those provisions listed in subdivision (a), the department shall establish and implement policies and procedures that include, but are not limited to, all of the following:

1. (1) Within 14 days following receipt of an application or request for which charges are to be assessed, or a later date as may be mutually agreed upon, the department and the applicant or requester shall hold a project planning meeting. Within 30 days from the date of the planning meeting, or within 30 days from the date that a complete application or request is received by the department, whichever is later, or by a later date mutually agreed upon, the department shall provide the applicant or requester an estimate that includes all of the following information:

   1. (A) A detailed description of the work to be performed or services to be provided.
   2. (B) The estimated billing rates for all classes of employees expected to work on the project. The department may adjust its billing rates not more than once every six months. Any adjustment in billing rates or other charges, including, but not limited to, pro rata costs and indirect costs, shall operate prospectively.
   3. (C) An estimate of all expected charges to be billed to the applicant or requester, to the extent that the department can project its time and costs in advance. The department may adjust this estimate subsequent to commencement of the project based on analysis of new information that supports the adjustment, including, but not limited to, such circumstances as a change in the scope of the original work, additional work that is needed to ensure protection of human health or safety or of the environment, or other circumstances that arise that require substantially more time and effort than was originally anticipated to complete the work. An adjustment may only be made after providing written notice and a detailed explanation of the change to the applicant or requester.

2. (2) The department shall adopt a billing system and procedures that include, but are not limited to, all of the following:

   1. (A) Billing rate and indirect cost rate schedules by employee job classification.
   2. (B) Standardized work task descriptions.
   3. (C) Issuance of invoices at least quarterly, and to the extent practicable, within 60 days from the date of completion of work for which the charge is assessed.
   4. (D) The inclusion of sufficient detail with each invoice so that the applicant or requester can relate the items on the invoice to the benefits received and to the estimate or charges provided pursuant to subparagraph (C) of paragraph (1). Invoices shall be supplemented with statements of any changes in rates and a detailed justification for any such changes.
   5. (E) Upon request and within a reasonable time, not to exceed 30 working days to the extent practicable, providing the applicant or requester with access to time records and other materials supporting the invoice.
   6. (F) The review of invoices for accuracy and appropriateness by a member of the department staff who has direct knowledge of the work or service performed.
   7. (G) The mailing of invoices to the contact person identified by the applicant or requester.
   8. (H) The development of policies and procedures for resolving disputes regarding charges billed pursuant to this section. The department shall ensure that the party responsible for resolving a dispute is not also responsible for, or performing, the work for which the charges are assessed. A person disputing an invoice shall notify the department in writing of the dispute and the reasons for the dispute within 45 days from the date of the invoice.
   9. (I) The development of a concise statement of its cost reimbursement policies and billing procedures, and making those policies and procedures, the dispute resolution policies and procedures, and other program guidance and policies readily available to any person requesting them.
