Yes, the practices stated in table 2d #1 (including the footnote: Sources have the option to utilize an oil analysis 
program as described in § 63.6625(i) in order to extend the specified oil change requirement in Table 2d of this 
subpart) will be appropriate for the larger engines.

Okay, thanks. So just to be clear, you're saying that the management practices in item #1 in Table 2d for 
smaller CI engines would also be appropriate for the larger engines?

OK. I was unaware of that decision. In that case, the criteria in 2d is preferred vs. the performance standards. 
Maintenance schedules already in place for these engines can be modified to incorporate the maintenance 
frequencies stated in table 2d.

Hi, 
Thank you for providing this information. However, we cannot use "in accordance with manufacturer 
specifications" as our standard. We got similar suggestions for the 2010 rulemaking and discussed why 
we cannot use that for our standard. Below is an excerpt from the response to comment document 
discussing the issue. This is on p. 238 of the document 
(http://www.epa.gov/ttn/atw/rice/existing_si_rice_rtc.pdf). 
 
"EPA does not agree with the commenters that it would be appropriate to simply specify that owners and 
operators follow the manufacturers recommended maintenance practices for the engine. EPA 
cannot delegate to manufacturers the final decision regarding the proper management practices 
required by section 112(d) of the CAA; nor can EPA allow management practices to change 
from engine to engine based on the views of multiple manufacturers."

Melanie, 
 
Per our phone conversation on Friday, Sept 14th, I have some information I’d like to provide to you regarding the 
subject comment letter and , more specifically, maintenance schedules for CI engines (> 500 HP) located on 
offshore platforms and exploratory drilling rigs that may become subject to the Subpart ZZZZ area source standards. 
 
Table 2d of the proposed rule specifies the following management practices for CI categories: 
a. Change oil and filter every 500 hours of operation or annually, whichever comes first; [Sources have the option to utilize 
an oil analysis program as described in § 63.6625(i) in order to extend the specified oil change requirement in Table 2d of 
this subpart.] 
 
b. Inspect air cleaner every 1,000 hours of operation or annually, whichever comes first, and replace as necessary; and 
c. Inspect all hoses and belts every 500 hours of operation or annually, whichever comes first, and replace as necessary. 
 
Since the maintenance schedules vary from one engine manufacturer to another (i.e., Wartsila, Caterpillar, etc.) and 
include the same items already provided in the rule above, requiring adherence to the manufacturer specifications 
for these maintenance items will meet the intent of the proposed rule and help assure good engine performance. 
a. Change oil and filter in accordance with manufacturer specifications; [Sources have the option to utilize an oil analysis 
program as described in § 63.6625(i) in order to extend the specified oil change requirement in Table 2d of this subpart.][ 
 
b. Inspect air cleaner in accordance with manufacturer specifications and replace as necessary; and 
c. Inspect all hoses and belts in accordance with manufacturer specifications and replace as necessary. 
 
Even though these engines can range in size up to several thousand horsepower, maintenance items and engine 
care are similar. Most engine owners will probably insist on following manufacturer specifications for engine 
maintenance in order to fulfill warranty obligations. 
 
I hope this provides a little more perspective for you from the operator’s view. Please reply or call me at your 
earliest convenience if you would like to discuss further.
