Sec.  178.70  Approval of UN pressure receptacles.

    (a) Initial design-type approval. The manufacturer of a UN pressure 
receptacle must obtain an initial design type approval from the 
Associate Administrator. The initial design type approval must be of the 
pressure receptacle design as it is intended to be produced. The 
manufacturer must arrange for an IIA, approved by the Associate 
Administrator in accordance with subpart I of part 107 of this chapter, 
to perform a pre-audit of its pressure receptacle manufacturing 
operation prior to having an audit conducted by the Associate 
Administrator or his designee.
    (b) IIA pre-audit. The manufacturer must submit an application for 
initial design type approval to the IIA for review. The IIA will examine 
the manufacturer's application for initial design type approval for 
completeness. An incomplete application will be returned to the 
manufacturer with an explanation. If an application is complete, the IIA 
will review all technical documentation, including drawings and 
calculations, to verify that the design

[[Page 901]]

meets all requirements of the applicable UN pressure receptacle standard 
and specification requirements. If the technical documentation shows 
that the pressure receptacle prototype design conforms to the applicable 
standards and requirements in Sec.  178.70, the manufacturer will 
fabricate a prototype lot of pressure receptacles in conformance with 
the technical documentation representative of the design. The IIA will 
verify that the prototype lot conforms to the applicable requirements by 
selecting pressure receptacles and witnessing their testing. After 
prototype testing has been satisfactorily completed, showing the 
pressure receptacles fully conform to all applicable specification 
requirements, the certifying IIA must prepare a letter of recommendation 
and a design type approval certificate. The design type approval 
certificate must contain the name and address of the manufacturer and 
the IIA certifying the design type, the test results, chemical analyses, 
lot identification, and all other supporting data specified in the 
applicable ISO design, construction and testing standard. The IIA must 
provide the certificate and documentation to the manufacturer.
    (c) Application for initial design type approval. If the pre-audit 
is found satisfactory by the IIA, the manufacturer will submit the 
letter of recommendation from the IIA and an application for design type 
approval to the Associate Administrator. An application for initial 
design type approval must be submitted for each manufacturing facility. 
The application must be in English and, at a minimum, contain the 
following information:
    (1) The name and address of the manufacturing facility. If the 
application is submitted by an authorized representative on behalf of 
the manufacturer, the application must include the representative's name 
and address.
    (2) The name and title of the individual responsible for the 
manufacturer's quality system, as required by Sec.  178.69.
    (3) The designation of the pressure receptacle and the relevant 
pressure receptacle standard.
    (4) Details of any refusal of approval of a similar application by a 
designated approval agency of another country.
    (5) The name and address of the production IIA that will perform the 
functions prescribed in paragraph (e) of this section. The IIA must be 
approved in writing by the Associate Administrator in accordance with 
subpart I of part 107 of this chapter.
    (6) Documentation on the manufacturing facility as specified in 
Sec.  178.69.
    (7) Design specifications and manufacturing drawings, showing 
components and subassemblies if relevant, design calculations, and 
material specifications necessary to verify compliance with the 
applicable pressure receptacle design standard.
    (8) Manufacturing procedures and any applicable standards that 
describe in detail the manufacturing processes and control.
    (9) Design type approval test reports detailing the results of 
examinations and tests conducted in accordance with the relevant 
pressure receptacle standard, to include any additional data, such as 
suitability for underwater applications or compatibility with hydrogen 
embrittlement gases.
    (d) Modification of approved pressure receptacle design type. 
Modification of an approved UN pressure receptacle design type is not 
authorized without the approval of the Associate Administrator. A 
manufacturer seeking modification of an approved UN pressure receptacle 
design type may be required to submit design qualification test data to 
the Associate Administrator before production. An audit may be required 
as part of the process to modify an approval.
    (e) Responsibilities of the production IIA. The production IIA is 
responsible for ensuring that each pressure receptacle conforms to the 
design type approval. The production IIA must perform the following 
functions:
    (1) Witness all inspections and tests specified in the UN pressure 
receptacle standard to ensure compliance with the standard and that the 
procedures adopted by the manufacturer meet the requirements of the 
standard;
    (2) Verify that the production inspections were performed in 
accordance with this section;

[[Page 902]]

    (3) Select UN pressure receptacles from a prototype production lot 
and witness testing as required for the design type approval;
    (4) Ensure that the various design type approval examinations and 
tests are performed accurately;
    (5) Verify that each pressure receptacle is marked in accordance 
with the applicable requirements in Sec.  178.72; and
    (6) Furnish complete test reports to the manufacturer and upon 
request to the purchaser. The test reports and certificate of compliance 
must be retained by the IIA for at least 20 years from the original test 
date of the pressure receptacles.
    (f) Production inspection audit and certification. (1) If the 
application, design drawing and quality control documents are found 
satisfactory, PHMSA will schedule an on-site audit of the pressure 
receptacle manufacturer's quality system, manufacturing processes, 
inspections, and test procedures.
    (2) During the audit, the manufacturer will be required to produce 
pressure receptacles to the technical standards for which approval is 
sought.
    (3) The production IIA must witness the required inspections and 
verifications on the pressure receptacles during the production run. The 
IIA selected by the manufacturer for production inspection and testing 
may be different from the IIA who performed the design type approval 
verifications.
    (4) If the procedures and controls are deemed acceptable, test 
sample pressure receptacles will be selected at random from the 
production lot and sent to a laboratory designated by the Associate 
Administrator for verification testing.
    (5) If the pressure receptacle test samples are found to conform to 
all the applicable requirements, the Associate Administrator will issue 
approvals to the manufacturer and the production IIA to authorize the 
manufacture of the pressure receptacles. The approved design type 
approval certificate will be returned to the manufacturer.
    (6) Upon the receipt of the approved design type approval 
certificate from the Associate Administrator, the pressure receptacle 
manufacturer must sign the certificate.
    (g) Recordkeeping. The production IIA and the manufacturer must 
retain a copy of the design type approval certificate and certificate of 
compliance records for at least 20 years.
    (h) Denial of design type application. If the design type 
application is denied, the Associate Administrator will notify the 
applicant in writing and provide the reason for the denial. The 
manufacturer may request that the Associate Administrator reconsider the 
decision. The application request must--
    (1) Be written in English and filed within 60 days of receipt of the 
decision;
    (2) State in detail any alleged errors of fact and law; and
    (3) Enclose any additional information needed to support the request 
to reconsider.
    (i) Appeal. (1) A manufacturer whose reconsideration request is 
denied may appeal to the PHMSA Administrator. The appeal must--
    (i) Be written in English and filed within 60 days of receipt of the 
Associate Administrator's decision on reconsideration;
    (ii) State in detail any alleged errors of fact and law;
    (iii) Enclose any additional information needed to support the 
appeal; and
    (iv) State in detail the modification of the final decision sought.
    (2) The PHMSA Administrator will grant or deny the relief and inform 
the appellant in writing of the decision. PHMSA Administrator's decision 
is the final administrative action.
    (j) Termination of a design type approval certificate. (1) The 
Associate Administrator may terminate an approval certificate issue 
under this section if it is determined that, because of a change in 
circumstances, the approval no longer is needed or no longer would be 
granted if applied for; information upon which the approval was based is 
fraudulent or substantially erroneous; or termination of the approval is 
necessary to adequately protect against risks to life and property.
    (2) Before an approval is terminated, the Associate Administrator 
will provide the manufacturer and the approval agency--
