Sec. 80.68  Compliance surveys.

    (a)(1) Beginning January 1, 2007, the compliance surveys for 
NOX emissions performance under this section shall cease to 
be required.
    (2) Beginning January 1, 2011, the compliance surveys for toxics 
emissions performance under this section shall cease to be required.
    (b) Compliance survey option 1. In order to satisfy the compliance 
survey requirements, any refiner or importer shall properly conduct a 
program of compliance surveys in accordance with a survey program plan 
which has been approved by the Administrator of EPA in each covered area 
which is supplied with any gasoline for which compliance is achieved on 
average that is produced by that refinery or imported by that importer. 
Such approval shall be based upon the survey program plan meeting the 
following criteria:
    (1) The survey program shall consist of at least four surveys which 
shall occur during the following time periods: one survey during the 
period January 1 through May 31; two surveys during the period June 1 
through September 15; and one survey during the period September 16 
through December 31.
    (2) The survey program shall meet the criteria stated in paragraph 
(d) of this section.
    (3) In the event that any refiner or importer fails to properly 
carry out an approved survey program, the refiner or importer shall 
achieve compliance with all applicable standards on a per-gallon basis 
for the calendar year in which the failure occurs, and may not achieve 
compliance with any standard on an average basis during this calendar 
year. This requirement to achieve compliance per-gallon shall apply ab 
initio to the beginning of any calendar year in which the failure 
occurs, regardless of when during the year the failure occurs.
    (c) Compliance survey option 2. A refiner or importer shall be 
deemed to have satisfied the compliance survey requirements described in 
paragraph (b) of this section if a comprehensive program of surveys is 
properly conducted in accordance with a survey program plan which has 
been approved by the Administrator of EPA. Such approval shall be based 
upon the survey program plan meeting the following criteria:

[[Page 701]]

    (1) The initial schedule for the conduct of surveys shall be as 
follows:
    (i) 120 surveys shall be conducted in 1995;
    (ii) 80 surveys shall be conducted in 1996;
    (iii) 60 surveys shall be conducted in 1997;
    (iv) 70 surveys shall be conducted in 1998 and thereafter.
    (2) This initial survey schedule shall be adjusted as follows:
    (i) In the event one or more ozone nonattainment areas in addition 
to the nine specified in Sec. 80.70, opt into the reformulated gasoline 
program, the number of surveys to be conducted in the year the area or 
areas opt into the program and in each subsequent year shall be 
increased according to the following formula:
[GRAPHIC] [TIFF OMITTED] TR16FE94.009

where:

ANSi = the adjusted number of surveys for year i; i = the 
opt-in year and each subsequent year
NSi = the number of surveys according to the schedule in 
paragraph (c)(1) of this section in year i; i = the opt-in year and each 
subsequent year
Vopt-in = the total volume of gasoline supplied to the opt-in 
covered areas in the year preceding the year of the opt-in
Vorig = the total volume of gasoline supplied to the original 
nine covered areas in the year preceding the year of the opt-in

    (ii) In the event that any covered area(s) fails a survey or survey 
series according to the criteria set forth in paragraph (d) of this 
section, the annual decreases in the numbers of surveys prescribed by 
paragraph (c)(1) of this section, as adjusted by paragraph (c)(2)(i) of 
this section, shall be adjusted as follows in the year following the 
year of the failure. Any such adjustment to the number of surveys shall 
remain in effect so long as any standard for the affected covered area 
has been adjusted to be more stringent as a result of a failed survey or 
survey series. The adjustments shall be calculated according to the 
following formula:
[GRAPHIC] [TIFF OMITTED] TR16FE94.010

where:

ANSi = the adjusted number of surveys in year i; i = the year 
after the failure and each subsequent year
Vfailed = the total volume of gasoline supplied to the 
covered area which failed the survey or survey series in the year of the 
failure
Vtotal = the total volume of gasoline supplied to all covered 
areas in the year of the failure
NSi = the number of surveys in year i according to the 
schedule in paragraph (c)(1) of this section and as adjusted by 
paragraph (c)(2)(i) of this section; i = the year after the failure and 
each subsequent year

    (3) The survey program shall meet the criteria stated in paragraph 
(d) of this section.
    (4) On each occasion the comprehensive survey program does not occur 
as specified in the approved plan with regard to any covered area:
    (i) Each refiner or importer who supplied any reformulated gasoline 
or RBOB to the covered area and who has not satisfied the survey 
requirements described in paragraph (b) of this section shall be deemed 
to have failed to carry out an approved survey program; and
    (ii) The covered area will be deemed to have failed surveys for VOC 
and NOX emissions performance, and survey series for benzene 
and toxic and NOX emissions performance.

the analysis of each sample collected during the course of the survey, 
unless the sample violates the applicable per-gallon maximum or minimum 
standards for the parameter being evaluated plus any enforcement 
tolerance that applies to the parameter (e.g., a sample that violates 
the benzene per-gallon maximum plus any benzene enforcement tolerance 
but meets other per-gallon maximum and minimum standards would be 
excluded from the benzene survey, but would be included in the surveys 
for parameters other than benzene).
    (ii) Any sample from a survey that violates any standard under Sec. 
80.41, or that constitutes evidence of the violation of any prohibition

Sec. 80.42(a)(1) with RVP = 7.2 and OXCON = 2.0 for covered areas 
located in VOC-Control Region 1 and using the VOC emissions equation at 
Sec. 80.42(a)(2) with RVP = 8.1 and OXCON = 2.0 for covered areas 
located in VOC-Control Region 2; and
    (C) The covered area shall have failed the simple model VOC survey 
if the VOC emissions reduction average of all survey samples is less 
than VOC emissions reduction survey standard calculated under paragraph 
(d)(8)(i)(B) of this section.
    (ii) The results of each complex model VOC emissions reduction 
survey shall be determined as follows:
    (A) For each complex model sample from the survey series, the VOC 
emissions reduction percentage shall be determined based upon the tested 
parameter values for that sample and the appropriate methodology for 
calculating VOC emissions reduction at Sec. 80.45;

    (B) The annual average of the toxics emissions reduction percentages 
for all samples from a survey series shall be calculated according to 
the following formula \2\:
---------------------------------------------------------------------------

    \2\ The formula requires, first, that the toxic reductions of 
samples taken in each one-week survey be averaged to obtain an average 
for each such survey. Then these survey averages are, themselves, 
averaged separately for high-ozone and non-high-ozone season surveys, to 
obtain two overall averages. These overall averages are each to be 
multiplied by a seasonal weight (0.468 for high-ozone season and 0.532 
for non-high ozone season) and the resulting products added together to 
obtain the average annual toxic emission reduction.
