12 Va. Admin. Code § 5-590-220 - Compliance with the Manual of Practice
A. The design guidelines set forth in Part
III Manual of Practice for Waterworks Design (12VAC5-590-640 et seq.) of this
chapter (Manual of Practice) specify general criteria for the design and
construction of waterworks . The commissioner may impose standards or
requirements that are more stringent than those contained in the Manual of
Practice when required to meet drinking water quality standards. Any special
standards or requirements with a federal mandate shall take precedence over the
criteria in the Manual of Practice and will be items that warrant careful
consideration at the preliminary engineering conference, referenced in
12VAC5-590-200.
B. Designs submitted for waterworks must
demonstrate that the waterworks will adequately safeguard public health.
Submissions that are in substantial compliance with the Manual of Practice and
any additional requirements of the commissioner , as noted in subsection A of
this section, will be approved. Justification for a design may be required for
those portions of the submitted design that differ from the criteria set forth
in the Manual of Practice and any established by the commissioner . Deviations
from mandatory criteria contained in the Manual of Practice shall be identified
and justified. For each deviation, the commissioner may issue a design
exception or require compliance with the criteria.
C. Final, complete, and detailed plans and
specifications submitted in accordance with the provisions of
12VAC5-590-200 and
12VAC5-590-210 will be evaluated
by the department as soon as practicable upon receipt. Plans and specifications
will be approved if they demonstrate substantial compliance with the design
criteria set forth in the Manual of Practice and any established by the
commissioner and if the waterworks , as constructed or modified, will be able to
function in compliance with Part II (12VAC5-590-340 et seq.) of this
chapter.
D. Compliance with the
Manual of Practice for transient noncommunity waterworks is allowed the
following exceptions as long as the conditions in subsection E of this section
are satisfied:
1. The design of a transient
noncommunity waterworks is not required to satisfy the professional engineer
licensure requirement of
12VAC5-590-210 under the following
conditions:
a. The waterworks shall serve no
more than 100 persons per day .
b.
The waterworks shall consist only of one supply of source water , a pressure
tank no greater than 250 gallon capacity, and a single service
connection .
c. The single service
connection shall be a building or structure of less than 5,000 square feet
total floor space. The determination of square footage shall be calculated
using the outside perimeter of the building or structure.
2. Although the owner of a transient
noncommunity waterworks is required to use a water well systems provider
certified by DPOR for drilling wells, the remainder of the waterworks facility
construction at a transient noncommunity waterworks may be performed by a
master plumber or a certified water well systems provider, as defined in §
54.1-1129.1 of the Code of
Virginia.
E. The
conditions for exceptions to the Manual of Practice for transient noncommunity
waterworks specified in subsection D of this section are as follows:
1. The owner shall submit a signed and dated
statement attached to the permit application, certifying that subsection D of
this section will be satisfied.
2.
The owner shall submit information related to the design, construction , and
materials used as required by the department .
