- HQ-OAR-20 11-0135 A. Introduction On Aug u st 26, 2013 EPA sta ff and represe ntati v e s of Ford Motor Company me t to di scuss issues and que stions related to the pro v i s i o n s ofthe Ti er 3 NPRM. A copy of t he agenda and attend ees is attached

. . B. Discussion: After personal intro du ctio n s and some br ief introductory r emarks, discu ssions followed th e agenda. The discussions were bri ef and basically followed Fo rd comm e nt s o n the T i e r 3 NPRM where applicable. There were t hree areas where mo re detailed di sc u ss ions occ urre d. R-factor: EPA summarized the curre nt s t aff thinking o n provisions for the fina l rule r ela t ed to reducing the potential for a dual test ing burden for early Tier 3 / LE V III certifications for EDVs and FEDVs (A copy of the power point slide u sed i s attac hed). Ford was generally s upportive of the se concepts and asked that EPA consider ho w a CA/ 177 states on l y vehicle would b e affected and that EPA consider an IUVP opt i on for EO on l y test ing. Ford indicate d that a 2020 MY for any new R

- factor, GHG , an d labeling provisions related to th e new certification fuel provis i o n s wou ld b e acceptable , but they n eed to see action on t h e final provisions by mid 2016. Evapo rative emissions phase-in: Ford asked that EPA s tro ngly consider in c luding the 20% T ier 3 ev ap/20% l eak s tandard complianc e option for the 2017 model year in the fina l rule as there are lead tim e and capita l cost implications for meeting the other optio n s. Ford also asked t hat EPA link the u se of the new Tie r 3 cert ific a ti on fuel for evaporative /refueling em i ss i o ns to compliance with Ti er 3 eva p o rati ve emi ssion stan d ard s ra t h er than a 2020 model year cut-off as proposed. Fo rd was also s upp ort i ve of l ong -t erm reciprocity between ARB and EPA for evaporative emission testin g. US06 PM standards: Based on new information from Ca lif o rnia which is availab le to Ford , E P A sta ff set forth the idea that the US06 PM stan dard s h ou ld b e 6 m g/ mi with a 1 2 mg / m i in-use standard in place durin g t h e pha se -in (through the 2021 MY production). Ford exp ress e d concern about variability and other unkn owns with regard to US 06 PM te s ting and asked EPA to consider a l ess s tringent standard and to retain th e interim in-u se s t a ndard concept. While F ord ha s provided data in the past, EPA asked them for any additional data the y h ave on US 06 PM.HDGE Certificat ion Gasoline: Ford agreed that HDGEs using the engine d ynamometer for emissions certification would have to be certified for emissions on Tier 3 certification fuel by the 2022 model year , but asked that EPA include an allowance for Tier 2 certification fuel carryover past 2022 for unique applications such as military vehicles (e.g., up to I % of total HDGE sa les )
. ORVR for HDGVs: EPA confirmed that the NPRM did not cover ORVR for incomplete HDGVs, but Ford agreed that the requirements could cover all complete HDGV s independent ofGVWR beginning in the 2018 MY.

•The in t erim approach reduces the testing burden by (1 )limit i ng t he requi r eme n t s for all
