Appendix (C). Procedure for Licensing Disciplinary Procedure.

(A) INITIATING A COMPLAINT AGAINST A LICENSEE

(1) Form of complaint: Filing. A person may register a complaint against a plumber licensed by the Plumbers' Examining Board. by filing a written complaint with the Department of Public Safety, Division of Fire Safety, 1311 US Route 302, Barre, VT, 05641. The written complaint must set forth, at a minimum, the nature, date and place of the alleged violations. The board may also initiate a license review procedure on its own motion by filing a complaint with the department.

(2) Verification. Upon receipt of a complaint, the department will verify the Vermont license number of the person against whom the complaint is lodged. If the person is unlicensed and the complaint alleges criminal conduct, the department will refer the complaint to the Office of the Attorney General. If the person is a licensee of the board, the department will docket the complaint and open an investigation file under the name and license number of the person.

(3) Investigating Panel. An investigating panel consisting of an investigator designed by the department and an assistant attorney general will be formed upon the docketing of a complaint. The assistant attorney general assigned to the case will head the panel and supervise the investigation of the complaint.

Upon docketing the complaint, the department will send a copy of all materials contained in the newly opened file, including a copy of the complaint, to the attorney general, and notify the attorney general of the name, address and phone number of its designated investigator. The department will also send copies of the materials to the investigator, and inform the investigator of the name of the division chief in the attorney general's office responsible for the investigation.

(2) Notice to the Licensee. The department will send written notice of the initiation of an investigation to the licensee against whom the complaint has been filed. The notice shall include a copy of the complaint and a copy of the statute and these rules. The notice will inform the licensee that inquiries or materials regarding the investigation should be addressed to the investigating panel at the address of the department.

(3) Notice to the Board. The department will send written notice to the Board indicating that an investigation has been instituted regarding a licensing complaint.

(4) The inspector assigned to investigate the complaint shall inspect the work which is the subject of the complaint and interview the complainant. The inspector may also meet and interview the licensee at the direction of the assistant attorney general assigned to the matter.

(C) RECOMMENDED ACTION.

(1) At the conclusion of the investigation the assistant attorney general assigned to the matter shall make a recommendation as to whether formal proceedings should commence against the licensee.

(2) If formal disciplinary proceedings are recommended, the assistant attorney general shall submit a complaint describing the alleged violations, and the rules or statutes violated, with the recommendation.

(3) If the licensee is willing to admit to the charges the assistant attorney general may explore the possibility of a stipulated settlement. A stipulated settlement must be approved by the board.

(4) If no disciplinary action is recommended the case will be closed and the complainant and the license will be notified that no further action will be taken at this time. The matter may be reopened if new evidence is presented.

(D) FORMAL HEARING BY THE BOARD.

(1) Notice and Place of Hearing. Upon the filing of a notice of charges by the investigating panel, the board will commence the hearing process by serving the notice of charges and a notice of the hearing upon the licensee. Notice will be served personally or by certified mail, return receipt requested. Copies will be sent to the members of the investigating panel and the complainant. The hearing will be scheduled at least 20 days after service.

(2) Failure to Appear. If the licensee fails to appear after proper notice has been given, the board shall hold the hearing and make a decision on the charges.

Appendix (D). Asbestos.

The Vermont Department of Health regulates the removal of asbestos containing materials, as well as the training of persons who remove asbestos containing materials, in the Vermont Regulations for Asbestos Control. For additional information, contact the Vermont Department of Health, Division of Environmental Health (800-439-8550).

Appendix (E). Design of Grease Interceptor -- Reference 2018 Ipc Section 1003.

EXAMPLE

STEP 1- Determine the cubic content of the fixture by multiplying length X width X depth.

Example: A sink 48" long by 24" wide by 12" deep Cubic content 48 X 24 X12 = 13,824 cubic in.

STEP 2 - Determine the capacity in gallons, 1 gal= 231 cubic inches.

Example: Contents in gals 13,824 = 59.8 gals.

STEP 3 - Determine actual drainage load. The fixture is usually filled to about 75% of capacity with waste water, the items being washed displace about 25% of the fixture content. Actual drainage load = 75% of fixture capacity.

Example: Actual Drainage Load.75 X 59.8 gals= 44.9 gals.

STEP 4 - Determine the flow rate and the drainage period. In general, good practices dictate a one minute drainage period, however where conditions permit, a 2 minute period is acceptable. Drainage period is the actual time required to completely empty the fixture.

Flow Rate = Actual Drainage Load

Drainage Period

Example: Calculate flow rate for I minute period.

Flow Rate 44.9 Gals = 44.9 GPM

1 Min.

For 2 minute period

Flow Rate 44.9 Gals = 22.5 GPM

2 Min.

STEP 5 - Select the interceptor which corresponds to the flow rate calculated. Note --Select larger size when flow rate falls between two sizes listed.

As a general rule it is good practice to size the Interceptor so that it's rated capacity is never less than 40% of the fixture capacity in gallons. In the example above the actual fixture capacity is 59.8 gals., and 40% of this would be 23.9 gals. or a Fig. 8025. It is readily seen that a drainage period other than one or two minutes can be used. If conditions justify, any period between one and two minutes is satisfactory, however, we do not recommend a period longer than 2 minutes. Using the 40% rule of thumb gives a drainage period of 17/8 minutes.
