Overmod
but the proposed Jordan’s Cove LNG terminal is slated to use C175s for its blackstart generation and the resource report (#9) in early September 2017 goes into specific detail of its notrogen-oxide emissions

There are no DEF consumptions given. On the title page for the blackstart generator (C175-16) it is designated as Tier 2!??

Aside from the notrogen typo: You will have to extract the meaningful data from several sections of the Jordans Cove material; it is not just in one place.

You will no doubt realize that by the time Jordans Cove is finished, the blackstart generation will have to be Tier 4, and I believe this is covered in earlier sections, where there are highly interesting interpretations of what a 'yearly emission' of NOx from the blackstart facility will be.  The point here is that (1) if you know the chemistry and stoich for the catalytic reduction and ammonia slip, which being molar will inherently be by weight, and (2) you have the emissions in lb, which are given at one point in tons/yr, and (3) you have the hours and duty cycle for the devices, you can figure out what the specific consumption of DEF HAS to be regardless of the nominal sfc of each of the generators (remember to account for both of them). 

Some of the other details are in the section specific to blackstart generation details, but isn't it clever that they discussed the emissions long before they start mentioning any 'technical' details, and don't repeat them in the technical-detail section (where I'd at least expect to have seen mention of the amount of NOx mitigation right along with sfc as a 'necessary' adjunct to legal operation...  It is hard to conceive of a CEM intentionally derating blackstart generation because the DEF tank is inadequate or the injectors slushed up...).

Meanwhile, at Daytona Beach you might note that all through the actual 'pitch' nothing is mentioned about the cost of consumables for NOx emission at all -- it's all rosy discussion of pollution benefits.  Only if you read down to the patched-in technical discussion -- and what purchasing agency or politician actually wants to read all that technical stuff? can't be very many because the exhibit itself has the chemistry wrong in a couple of places, notably showing NO2 in the final exhaust (!!!) which it would take an awful lot of people being stupid to leave in, imnsho -- do you begin to realize that stuff with nasty characteristics is going to be expensively piped in from somewhere with some expensive ancillary systems to help it along.  (On the other hand, it's nice to have the C175 data on weight and configuration of required SCR equipment, even if it is X'ed out).  I don't believe even in the summary they mention that there are operating costs involved above those for the fuel burn...

Power Generation the EPA laws are different, Black Start is considered "emergency" use. Provided the run time is under 100 hours annually. 

Stationary engines 750+ bhp for emegency/black start are to be Tier II.

Brings up another discussion EPA laws in other industries utilizing Diesel engines.

Truck industry, Peterbilt, Kenworth and Daimler manufactures "glider kits" which is a new truck with no engine. They can use a certified engine from basically any existing truck that has been taken out of service.

Which now has expanded to 20,000 units annually. Orginally the plan was for Gliders to use GHG phase 2 engines after 2017, Scott Pruitt is leading the EPA to re open this loophole.

Imagine if GE and EMD could sell new locomotives for the railroads to install -9 and SD60 engines in.

I'd prefer the EPA to be more consistent.

Problem there is that Jordan’s Cove is specifically figured as 200 hours per year, which I think is why the references in the document to Tier 4.

Can someone check the language and confirm?
