12VAC5-610-447. Evaluation period for provisionally approved systems.
A. Evaluation criteria. Prior to receiving general approval and being incorporated into this chapter, systems with provisional approval shall be evaluated for not less than five years. The division should conduct an annual review of systems with provisional approval. The review, at a minimum, should be based on the following information submitted by the manufacturer; however, nothing shall prevent the department from verifying, augmenting or otherwise collecting additional information on the performance and operation of the system.
1. A field review of a sample of the systems installed. The sample shall include a representation of systems of newer and older installations and systems installed under different site and system limitations. System limitations will frequently be unique to each system and therefore the criteria used to select systems of different manufacturers will vary according to the nature and design of the system. The division shall determine the sample size to be evaluated and the criteria for sample selection.
2. Interviews with a sample of system owners to determine customer satisfaction and customer opinions. This sample may or may not be the same as the sample of systems reviewed under subdivision 1 of this subsection.
3. A review of the manufacturer's or the distributor's records relating to system maintenance and customer complaints. Failure to maintain accurate and up-to-date records of maintenance actions and customer complaints may delay or prevent completing a product review.
4. A review of any sample results which may be collected from or around any of the systems.
5. Other information as deemed appropriate by the division which relates to evaluating the effect of the system, method or process on ground water or public health.
B. Tracking of site locations. The manufacturer shall submit to the department records on the numbers, locations and operation of all provisionally approved systems on a quarterly basis not later than the 15th day of the month following the quarter.
C. Revisions to provisional approval. During the period of provisional approval, the department may revise any aspect of the site, soil and design requirements for that system based on experience gained during the use of the systems. The department shall work with the applicant to revise the approval by agreement, but shall not be prohibited from doing so without the consent of the applicant if warranted by health or environmental concerns. The revised provisional approval shall apply to any systems for which an application is filed after the revision is made.
