TITLE 40--PROTECTION OF ENVIRONMENT
CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
PART 86--CONTROL OF EMISSIONS FROM NEW AND IN-USE HIGHWAY VEHICLES AND ENGINES--Table of Contents
Subpart A--General Provisions for Emission Regulations for 1977 and
Sec. 86.007-21 Application for certification.
Section 86.007-21 includes text that specifies requirements that
differ from Sec. 86.004-21, 86.094-21 or 86.096-21. Where a paragraph in
Sec. 86.004-21, 86.094-21 or 86.096-21 is identical and applicable to
Sec. 86.007-21, this may be indicated by specifying the corresponding
paragraph and the statement ``[Reserved]. For guidance see Sec. 86.004-
21.'', ``[Reserved]. For guidance see Sec. 86.094-21.'', or
``[Reserved]. For guidance see Sec. 86.096-21.''.
(a) through (b)(3) [Reserved]. For guidance see Sec. 86.094-21.
(b)(4)(i) [Reserved]. For guidance see Sec. 86.004-21.
(b)(4)(ii) through (b)(5)(iv) [Reserved]. For guidance see
Sec. 86.094-21.
(b)(5)(v) through (b)(6) [Reserved]. For guidance see Sec. 86.004-
21.
(b)(7) and (b)(8) [Reserved]. For guidance see Sec. 86.094-21.
(b)(9) and (b)(10) [Reserved]. For guidance see Sec. 86.004-21.
(c) through (j) [Reserved]. For guidance see Sec. 86.094-21.
(k) and (l) [Reserved]. For guidance see Sec. 86.096-21.
(m) and (n) [Reserved]. For guidance see Sec. 86.004-21.
(o) For diesel heavy-duty engines, the manufacturer must provide the
following additional information pertaining to the supplemental steady-
state test conducted under Sec. 86.1360-2007:
(1) Weighted brake-specific emissions data (i.e., in units of g/bhp-
hr), calculated according to Sec. 86.1360-2007(e)(5), for all pollutants
for which an emission standard is established in Sec. 86.004-11(a);
(2) Brake specific gaseous emission data for each of the 13 test
points (identified under Sec. 86.1360-2007(b)(1)) and
[[Page 78]]
the 3 EPA-selected test points (identified under Sec. 86.1360-
2007(b)(2));
(3) Concentrations and mass flow rates of all regulated gaseous
emissions plus carbon dioxide;
(4) Values of all emission-related engine control variables at each
test point;
(5) Weighted break-specific particulate matter (i.e., in units of g/
bhp-hr);
(6) A statement that the test results correspond to the maximum
NOX producing condition specified in Sec. 86.1360-2007(e)(4).
The manufacturer also must maintain records at the manufacturer's
facility which contain all test data, engineering analyses, and other
information which provides the basis for this statement, where such
information exists. The manufacturer must provide such information to
the Administrator upon request;
(7) A statement that the engines will comply with the weighted
average emissions standard and interpolated values comply with the
Maximum Allowable Emission Limits specified in Sec. 86.007-11(a)(3) for
the useful life of the engine. The manufacturer also must maintain
records at the manufacturer's facility which contain a detailed
description of all test data, engineering analyses, and other
information which provides the basis for this statement, where such
information exists. The manufacturer must provide such information to
the Administrator upon request.
(p)(1) The manufacturer must provide a statement in the application
for certification that the diesel heavy-duty engine for which
certification is being requested will comply with the applicable Not-To-
Exceed Limits specified in Sec. 86.007-11(a)(4) when operated under all
conditions which may reasonably be expected to be encountered in normal
vehicle operation and use. The manufacturer also must maintain records
at the manufacturers facility which contain all test data, engineering
analyses, and other information which provides the basis for this
statement, where such information exists. The manufacturer must provide
such information to the Administrator upon request.
(2) For engines equipped with exhaust gas recirculation, the
manufacturer must provide a detailed description of the control system
the engine will use to comply with the requirements of Sec. 86.007-
11(a)(4)(iii) and Sec. 86.1370-2007(f) for NTE cold temperature
operating exclusion, including but not limited to the method the
manufacturer will use to access this exclusion during normal vehicle
operation.
(3) For each engine model and/or horsepower rating within an engine
family for which a manufacturer is applying for an NTE deficiency(ies)
under the provisions of Sec. 86.007-11(a)(4)(iv), the manufacturer's
application for an NTE deficiency(ies) must include a complete
description of the deficiency, including but not limited to: the
specific description of the deficiency; what pollutant the deficiency is
being applied for, all engineering efforts the manufacturer has made to
overcome the deficiency, what specific operating conditions the
deficiency is being requested for (i.e., temperature ranges, humidity
ranges, altitude ranges, etc.), a full description of the auxiliary
emission control device(s) which will be used to maintain emissions to
the lowest practical level; and what the lowest practical emission level
will be.
