The owner or operator of an underground piping system is
responsible for and shall ensure that all new underground liquid fertilizer
piping systems comply with this rule and shall maintain all records required by
paragraph (D) of rule
901:5-2-07 of the
Administrative Code.
If the underground piping system is to be used and designed as
pressure piping without secondary containment, a professional engineer must
certify, by letter to the department, that the underground piping system as
designed meets the following requirements:
(A) All underground piping systems
in place prior to the effective date of this rule shall be permitted to
continue in operation until such time that any underground component of the
system requires repair, upgrade, modification or replacement, at which time the
entire underground portion of the system shall comply with the requirements of
this rule.
(1) All systems, whether existing or
new, shall comply with this rule by January 1, 2012.
(B)(A)
The department shall be notified by the owner prior to:
(1) Beginning construction of a new liquid
fertilizer underground piping system; or
(2) Conducting repair, upgrade, modification
or replacement of any existing fertilizer underground piping system.
(C)(B) All underground
piping systems shall be constructed as follows:
(1) Piping is permitted without secondary
containment provided that one of the following
"
ASTM international standards
" are met:
(a) The piping is made of 304 or 316
stainless steel pipe per ASTM A 312 minimum schedule 10;
or
(b) Chlorinated poly vinyl chloride
poly(vinyl chloride) (CPVC) plastic pipe per ASTM F
442 and the DR not to exceed 17; or
(c)
High density polyethylene (HDPE) plastic pipe per ASTM D
3350-05
2250-21 with a DR not to exceed 17;
or
(d)
Polyvinyl
chloride
Poly(vinyl choride) (PVC)
plastic pipe per ASTM D 2241-05
2241-20 and DR not to exceed 17;
or
(e) Carbon steel pipe per ASTM A 53 minimum
schedule 40, coated and wrapped; or
(f) Carbon steel pipe per ASTM A 53 minimum
schedule 80, unprotected.
(2) All appurtenances shall be made of
materials recommended by the manufacturer or materials specified in applicable
standards for the type of liquid carried.
(3) Generally accepted engineering standards
and practices, as defined in paragraph
(R)
(K) of rule
901:5-2-01 of the
Administrative Code, shall be followed for any pipe material used. Such
standards and practices shall also be followed with regard to the trench, soil,
backfill, pipe design, connections, secondary containment, supports, and
adaptations to facilities for hydrostatic testing.
(4) The underground piping system shall be
constructed so that hydrostatic testing can be performed.
(D)(C)
Hydrostatic testing:
(1) Hydrostatic testing
shall be done to ensure the integrity of any underground piping
system.
(2) Hydrostatic testing
shall be conducted twice per calendar year at a minimum of six month intervals;
or
(3) Hydrostatic testing shall be
conducted upon request of the department if the department has reason to
believe that the system has been compromised.
(4) The method of hydrostatic testing for all
underground piping system materials shall be ASTM F
2164-02
2164-21,
unless the owner or operator has certification from a professional engineer
that the standard used meets or exceeds ASTM F
2164-02
2164-21.
(a) If the system fails to meet the
requirements set forth in ASTM F 2164-02
2164-21, then
the owner or operator must report said failure to the department within
forty-eight hours upon finding such failure; and
(b) The system must be repaired, modified or
replaced immediately.
(5) A calibrated test gauge must be used for
testing.
(a)
Certification
Certification of the test gauge
must be traceable to the standards of NIST.
(6) The pressure application tap and pressure
gauge taps for hydrostatic testing must be labeled as such.
(E)(D) Pneumatic or
pressurized air testing is prohibited.
(F)(E) If the underground
piping system does not meet the requirements as set forth in this rule
secondary containment is required. Secondary containment shall be a pipe within
a pipe that drains into a sump collection that can be inspected for leakage.
The secondary collection and sump shall be protected against the collection of
rainwater, runoff, and groundwater; and
(G)(F) The transfer pipe
must be one identified in the ASTM standards referenced in paragraphs
(C)(1)(a)
(B)(1)(a) to (C)(1)(f)
(B)(1)(f) of
this rule.
(H)(G) All materials
incorporated or referenced in this rule can be found in rule
901:5-2-01 of the
Administrative Code.
