52 Pa. Code § 59.135 - Construction, operation and maintenance, and other reports to the Commission
(a)
Scope. This section establishes requirements for a hazardous
liquid public utility reporting construction, O&M and other
activities.
(b)
Time frame
for notice. A hazardous liquid public utility shall notify the
Pipeline Safety Section of the following:
(1)
Proposed major construction or proposed major maintenance involving an
expenditure in excess of $300,000 or 10% of the cost of the pipe in service,
whichever is less, 30 days prior to commencement.
(2) Planned maintenance, verification digs
and assessments involving an expenditure in excess of $50,000, and the
unearthing of dents, pipe ovality features, cracks, gouges or corrosion
anomalies, or other suspected metal losses 10 days prior to commencement,
except where the hazardous liquid public utility determines this activity must
occur prior to 10 days from the date of discovery of the condition to be
investigated or addressed, in which instance notification must occur as soon as
practicable.
(3) Unplanned or
emergency maintenance, verification digs and assessments due to excavation
damage, washouts or unplanned replacements of a pipeline section or cut out as
soon as practicable, but no later than 2 hours after discovery.
(4) A change in excavation technique (for
example, from open cut to TT or vice versa, as well as a change from one TT to
another TT) to the hazardous liquid public utility's established construction
methodologies at least 48 hours prior to commencement.
(5) The introduction of a hazardous liquid 30
days prior to the introduction. At a minimum, this notice must also be given to
public officials in writing by means of electronic mail.
(c)
Content of notice
generally. Notice provided to the Pipeline Safety Section under
subsection (b)(1)-(5) must include the following information:
(1) The hazardous liquid public utility's
name.
(2) Pipeline route.
(3) Length of the pipeline.
(4) The counties and municipalities
traversed.
(5) Estimated start and
completion dates.
(6) Pipeline
identification information.
(7) A
change in flow direction.
(8)
Commodity or product.
(d)

(v) Longitudinal joint type.
(vi) Specified minimum yield strength, or
SMYS, (psi).
(vii) Nominal ultimate
strength (psi).
(viii) Fracture
toughness by applicable material testing.
(ix) Mill test pressure (psi).
(x) A statement indicating whether pipe is
new or used.
(xi) If used pipe is
employed, a description of the inspection and reconditioning procedures
used.
(xii) The physical and
chemical specifications of pipe verified by outside laboratories.
(3)
Operating pressure and
stress.
(i) Maximum operating
pressure, P (psi).
(ii) Calculated
pipe stress (hoop stress) = PD/2t (psi).
(iii) Ratio of pipe stress to SMYS
(percent).
(4)
Welding.
(i) Percentage of
welds to be radiographed, by location.
(ii) The method for certifying the
radiographic technician.
(5)
Railroad, road and water
crossings.
(i) The location of each
pipe at a lake, river, stream or creek crossing, and a description of special
construction precautions to be followed.
(ii) Encroachments to railroads or roads, by
location, and a description of special construction precautions to be
followed.
(iii) The location of
each pipe at a railroad and road crossing and a statement indicating whether
each pipe is cased or uncased and whether heavier wall carrier pipe is used. If
a pipe is uncased, the notification must provide the reason.
(6)
Valves.
(i) Number and spacing of manual
sectionalizing valves.
(ii) The
type, make and location of any automatic valves.
(7)
Minimum cover and
clearance.
(i) The location, nature
of the problem, cover and clearance, if the minimum prescribed cover and
clearance cannot be maintained.
(ii) Special precautions to be
observed.
(8)
Piping.
(i) The type of
field coating.
(ii) The type of
coating test.
(iii) The type of
cathodic protection system.
(9)
Pressure and leakage
tests.
(i) Test pressure.
(ii) Test medium.
(iii) Test duration.
(iv) The length of the test
section.
(10)
Pipeline rights-of-way.
(i) A
statement indicating whether the necessary rightof-way has been obtained from
each party having an interest in the right-of-way.
(ii) A statement indicating whether formal
approval and all necessary permits have been obtained from appropriate
agencies.
(e)
Information to be provided upon request for assessments and
verification digs involving an expenditure in excess of $50,000 and the
unearthing of suspected anomalies. Upon request, a hazardous liquid
public utility shall provide the following information to the Pipeline Safety
Section with its notice under subsection (b)(2):
(1) Identification information for the
pipeline to be assessed.
(2) The
location range of the area to be assessed.
(3) A description of the
assessment.
