# §60.4360a. How do I use fuel sulfur analysis to determine the total sulfur content of the fuel combusted in my stationary combustion turbine?

- (a) If you elect to demonstrate compliance with a SO2 emissions standard according to [§ 60.4333a(d)(2)](/cfr/40/60.4333a.md?p=d-2), the fuel analyses may be performed either by you, a service contractor retained by you, the fuel vendor, or any other qualified agency as determined by the Administrator or delegated authority using the sampling frequency specified in [§ 60.4370a](/cfr/40/60.4370a.md).
- (b) Representative fuel analysis samples may be collected either by an automatic sampling system or manually. For automatic sampling, follow ASTM D5287-97 (Reapproved 2002) (incorporated by reference, see [§ 60.17](/cfr/40/60.17.md)) for gaseous fuels or ASTM D4177-95 (Reapproved 2000) (incorporated by reference, see [§ 60.17](/cfr/40/60.17.md)) for liquid fuels. For reference purposes when manually collecting gaseous samples, see Gas Processors Association Standard 2166-17 (incorporated by reference, see [§ 60.17](/cfr/40/60.17.md)). For reference purposes when manually collecting liquid samples, see either Gas Processors Association Standard 2174-14 or the procedures for manual pipeline sampling in [section 14](/cfr/40/14.md) of ASTM D4057-95 (Reapproved 2000) (both of which are incorporated by reference, see [§ 60.17](/cfr/40/60.17.md)).
- (c) Each collected fuel analysis sample must be analyzed for the total sulfur content of the fuel and heating value using the methods specified in paragraph [(c)(1)](#c-1) or [(2)](#c-2) of this section, as applicable to the fuel type.
  - (1) For the sulfur content of liquid fuels, ASTM D129-00 (Reapproved 2005), or alternatively D1266-98 (Reapproved 2003), D1552-03, D2622-05, D4294-03, D5453-05, D5623-24, or D7039-24 (all of which are incorporated by reference, see [§ 60.17](/cfr/40/60.17.md)). For the heating value of liquid fuels, ASTM D240-19 or D4809-18 (both of which are incorporated by reference, see [§ 60.17](/cfr/40/60.17.md)); or
  - (2) For the sulfur content of gaseous fuels, ASTM D1072-90 (Reapproved 1999), or alternatively D3246-05, D4468-85 (Reapproved 2000), D6667-04, or D5504-20 (all of which are incorporated by reference, see [§ 60.17](/cfr/40/60.17.md)). If the total sulfur content of the gaseous fuel during the most recent compliance demonstration was less than half the applicable standard, ASTM D4084-05, D4810-88 (Reapproved 1999), D5504-20, or D6228-98 (Reapproved 2003), or Gas Processors Association Standard 2140-17 or 2377-86 (all of which are incorporated by reference, see [§ 60.17](/cfr/40/60.17.md)), which measure the major sulfur compounds, may be used. For the heating value of gaseous fuels, ASTM D1826-94 (Reapproved 2003), or alternatively D3588-98 (Reapproved 2003), D4891-89 (Reapproved 2006), or Gas Processors Association Standard 2172-09 (all of which are incorporated by reference, see [§ 60.17](/cfr/40/60.17.md)).
