Re: New Crude Diff - ICE CLK 1a Index Future and Related Amendments (4 of 6)

Submission Pursuant to Section 5c(c)(1) of the Act and Regulation 40.2

Dear Mr. Kirkpatrick:

Pursuant to Section 5c(c)(1) of the Commodity Exchange Act, as amended (the “CEA”), and Commission

Regulations 40.2, ICE Futures U.S., Inc. (“Exchange”) submits, by written certification, new Rules

18.E.159, 19.C.150-19.C.153, and 19.A.79, amendments to Rule 19.01, and amendments to Resolutions 1

and 2 of Chapters 18 and 19. The new rules and amendments provide for five new futures and one new

option on futures contracts, which will be listed on or about September 25, 2023, or such other date as the

Exchange shall determine which shall be no sooner than the second business day following the business

day on which this submission is received by the Commission.

Physical Environmental Option on Futures Contract

a. Option on California Low Carbon Fuel Standard Credit (OPIS) Future

The Exchange is listing one new option on futures contract calling for the delivery of California Low

Carbon Fuel Standard Credits, as published by OPIS. The options are European-style and are based on the

Exchange’s California Low Carbon Fuel Standard Credit (OPIS) Futures contracts. The new contract will

be margined based on futures-style margining, for which the premium for the contracts will be paid in full

at maturity, as opposed to equity-style margining. The options will cease trading at 4:00 p.m. (EPT) on the

15th calendar day of the delivery month. If the 15th calendar day is not a business day, then the expiry day

will be the first business day following the 15th calendar day of the delivery month, consistent with other

Physical Environmental options contracts. Options will exercise at 5:30pm EPT on the contract’s last

trading day.

The contract sizes, minimum price fluctuations, No-Cancellation Ranges (NCRs), spot month position

limits and single and all month accountability levels are provided in relevant documents attached as Exhibit

A. All relevant terms of the aforementioned Physical Environmental option on futures contract are similar

to other Physical Environmental option on futures contracts listed by the Exchange. The listing cycle and

other relevant specifications are provided in the contract specifications in Exhibit A. The new contract is

block eligible. The minimum block trade sizes have been set consistent with existing Physical

Environmental contracts. New Exchange Rule 18.E.159 lists the new option on futures contract. The

Exchange has set spot month position limits and single and all-months-combined accountability levels for

the option on futures contract at levels identical to those of existing contracts listed by the Exchange for
LCFS futures contracts. Positions held in the new option on futures contract will be aggregated with the

underlying futures contract (LFS) for position limits and single and all-month accountability purposes.

Additionally, it is the Exchange’s good faith belief that the contract does not meet the definition of

referenced contract as prescribed in CFTC Regulation §150.1.1

Oil Americas Futures and Option on Futures Contracts

a. Crude Diff - Argus Bakken (DAPL) Crude Oil Trade Month Future

The Exchange is listing one monthly cash settled futures contract, the Crude Diff - Argus Bakken (DAPL)

Crude Oil Trade Month Future (“DPL”), which is based on the average of the daily prices published by

Argus for crude oil streams at Bakken DAPL (or, Dakota Access Pipeline) basis WTI Calendar Month

Average (CMA NYMEX). Generally, the DPL futures contract will reflect the value of crude streams

originating from the Bakken formation with a delivery point near Patoka, IL. The relevant market consists

of any crude oil stream meeting the prevailing grade and quality specifications of Bakken crude oil. The

contract supplements the existing suite of Oil Americas and crude oil contracts currently listed by the

Exchange. The contract will cease trading at the close of trading on the last business day that falls on or

before the 25th calendar day of the month prior to the contract month. If the 25th calendar day is a weekend

or holiday, trading shall cease on the first business day prior to the 25th calendar day. The contract will settle

to a price in USD and cents per barrel based on the average of the specified daily prices published by Argus

during the determination period.

b. Crude Diff - ICE HITAN EDM 1a Index Future

The Exchange is listing one monthly cash settled futures contract, the Crude Diff - ICE HITAN EDM 1a

Index Future (“HTN”) is a monthly cash settled future based on the ICE HITAN Edmonton 1a Monthly

Volume Weighted Average Price Index (ICE HITAN EDM 1a). Generally, the HTN futures contract will

reflect the values of Canadian High TAN crude streams at Edmonton, Alberta. The crude streams included

in the index are Access Western Blend (“AWB”), Western Canadian Dilbit (“WDB”), Surmont Heavy

Dilbit (“SHD”), and Kearl Lake (“KDB”). The contract supplements the existing suite of Oil Americas and

crude oil contracts currently listed by the Exchange. Trading shall cease one Canadian business day prior

to the Notice of Shipments (NOS) date on the Enbridge Pipeline. The NOS date occurs on or about the 20th

calendar day of the month, subject to confirmation by Enbridge Pipeline. The official schedule for the NOS

dates will be made publicly available by Enbridge Pipeline prior to the start of each year. The contract will

settle to a price in USD and cents per barrel based on the ICE HITAN EDM 1a Index, as published by ICENGX. The index pricing period for each contract month begins on the first Canadian business day of the

calendar month prior to the contract month and ends on the Canadian business day prior to the NOS date

(as published by Enbridge) in the same calendar month.

c. Crude Diff - ICE CLK 1a Index Future

The Exchange is listing one new monthly contract, the Crude Diff - ICE CLK 1a Index Future (“CLK”) is

a monthly cash settled future based on the ICE Cold Lake 1a Monthly Volume Weighted Average Price

Index (ICE CLK 1a). Generally, the CLK contract will reflect the market premium (or discount) between

the value of West Texas Intermediate (“WTI”), a US light sweet crude oil blend, and the value of crude oil

extracted from oil sand deposits in the Cold Lake basin of Alberta, Canada destined to flow on Cold Lake

pipelines at Edmonton and on Enbridge Transfer, Cold Lake, Gibson and Express pipelines at Hardisty.

The contract supplements the existing suite of Oil Americas and crude oil contracts currently listed by the

Exchange. Trading shall cease one Canadian business day prior to the Notice of Shipments (NOS) date on

the Enbridge Pipeline. The NOS date occurs on or about the 20th calendar day of the month, subject to

confirmation by Enbridge Pipeline. The official schedule for the NOS dates will be made publicly available

1 17 C.F.R. § 150.1 (October 15, 2020) (providing for referenced contract definition).
by Enbridge Pipeline prior to the start of each year. The contract will settle to a price in USD and cents per

barrel based on the ICE CLK 1a Index, as published by ICE-NGX. The index pricing period for each

contract month begins on the first Canadian business day of the calendar month prior to the contract month

and ends on the Canadian business day prior to the NOS date (as published by Enbridge) in the same

calendar month.

d. Crude Diff - Argus Canadian High TAN (Houston) Crude Oil Trade Month Future

The Exchange is listing one new monthly cash settled futures contract, the Crude Diff - Argus Canadian

High TAN (Houston) Crude Oil Trade Month Future (“ARX”) is a cash settled future based on the Argus

daily assessment price for Canadian High TAN basis Houston. Generally, the ARX futures contract will

reflect the value of Canadian High TAN crude streams with a delivery point of Houston, Texas. The relevant

market consists of any crude oil stream meeting the prevailing grade and quality specifications of Canadian

High TAN crude oil. The futures contract supplements the existing suite of Oil Americas contracts currently

listed by the Exchange. The contract will cease trading at the close of trading on the last business day that

falls on or before the 25th calendar day of the month prior to the contract month. If the 25th calendar day

is a weekend or holiday, trading shall cease on the first business day prior to the 25th calendar day. The

contract will settle to a price in USD and cents per barrel based on the average of the “Diff weighted

average” quotations appearing in the “Argus Crude” report under the heading "US Gulf Coast and

Midcontinent" subheading “Texas” for “Canadian High TAN Houston”, basis CMA Nymex” for each

business day (as specified below) in the determination period.

e. Biodiesel Outright - Soybean Oil (RBD) (Fastmarkets) 1st Line Future

The Exchange is listing one new monthly cash settled futures contract, the Biodiesel Outright - Soybean

Oil (RBD) (Fastmarkets) 1st Line Future (“SRB”), which is a monthly cash settled future based on the

Fastmarkets daily assessment price for Soybean Oil (RBD). The contract generally represents the price of

refined, bleached, and de-odorized (RBD) soybean oil in central Illinois during the contract month. RBD

soybean oil has been cleaned to remove impurities and has been degummed to remove lecithin and

additional fatty acids. Additional refining removes pigmentation and odors from the oil. RBD soybean oil

has various commercial and industrial uses, such as glues and adhesives and in the production of various

food products. Increasingly, the oil is being utilized as an input in biodiesel fuel markets. The monthly

futures contract supplements the existing suite of Oil Americas contracts currently listed by the Exchange.

The contract will cease trading on the last trading day of the contract month, at which time the contract will

settle to a price in USD and cents per pound based on the average of daily prices made public by Fastmarkets

for Soybean Oil (RBD) for each business day in the contract month. Further, amendments to Rule 19.01

add Fastmarkets to the list of defined terms associated with the Exchanges’ futures and options products.

The contract size, minimum price fluctuation, Interval Price Limits (IPLs) and IPL recalculation times,

where applicable, No-Cancellation Ranges (NCRs), spot month position limits and single and all month

accountability levels are provided in relevant documents attached as Exhibit A. All relevant terms of the

contracts are similar to other Oil Americas futures contracts listed by the Exchange. Each of the new

contracts are block eligible. The minimum block trade size has been set consistent with existing Oil

Americas futures contracts. The listing cycle and other relevant specifications are provided in the contract

specifications in Exhibit A. New Exchange Rules 19.A.79 and 19.C.150-19.C.153 list the new futures

contracts. Where applicable, a Deliverable Supply Analysis detailing the methodology the Exchange used

to determine the spot month position limits for the Oil Americas contracts is attached hereto as Exhibit B.

The Exchange has set single and all month accountability levels for such contracts consistent with the spot

month position limits for the products. The Exchange believes that the DPL contract is substantially the

same as an existing contract (look-a-likes) currently listed on another designated contract market. Therefore,

pursuant to CFTC Regulation 150.5(b)(3), the Exchange has set spot month position limits and single and

all-months-combined accountability levels for DPL at levels identical to those of existing contracts listed
by such designated contract market, in compliance with the requirement.2 Additionally, it is the Exchange’s

good faith belief that the above-referenced Oil Americas futures contracts do not meet the definition of

referenced contract as prescribed in CFTC Regulation §150.1.

Certifications

The rules and amendments establishing the new futures and option on futures contracts’ terms and

conditions are to become effective on the second business day following the business day on which this

submission is received by the Commission. The Exchange is not aware of any substantive opposing views

to the new futures and option on futures contracts. The Exchange certifies that the rule amendments comply

with the requirements of the Act and the rules and regulations promulgated thereunder. The Exchange has

reviewed the designated contract market core principles ("Core Principles") as set forth in the Act and has

determined that the listing of the contracts complies with the following relevant Core Principles:

COMPLIANCE WITH RULES

The terms and conditions of the new futures and option on futures contracts are set forth in new

Rules 18.E.159, 19.A.79, and 19.C.150-19.C.153, amendments to Rule 19.01, and amendments to

Resolutions 1 and 2 of Chapters 18 and 19, and will be enforced by the Exchange. In addition,

trading of the contracts is subject to all relevant Exchange rules which are enforced by the Market

Regulation Department.

CONTRACTS NOT READILY SUBJECT TO MANIPULATION

The new futures and option on futures contracts are not readily subject to manipulation as they are

based on established and liquid underlying cash markets. In addition, trading of the new contracts

will be monitored by the Market Regulation Department.

POSITION LIMITS OR ACCOUNTABILITY

Positions in the new futures and option on futures contracts will be subject to position limits and

accountability levels set by the Exchange. As described above, such position limits are based upon

existing levels set for substantially similar products at the Exchange or another designated contract

market or based on the deliverable supply of the cash commodity underlying the contract. Positions

held in the new option on futures contract will be aggregated with the futures contract underlying

the option contract for purposes of position limits and accountability.

FINANCIAL INTEGRITY OF CONTRACTS

The new futures and option on futures contracts will be cleared by ICE Clear Europe, a registered

derivatives clearing organization subject to Commission regulation, and carried by registered

futures commission merchants qualified to handle customer business.

The Exchange is not aware of any opposing views expressed by members or others regarding the listing of

the new futures and option on futures contracts and the adoption of related amendments. The Exchange

further certifies that concurrent with this filing a copy of this submission was posted on the Exchange’s

website, which may be accessed at: (https://www.theice.com/futures-us/regulation#rule-filings).

2 17 C.F.R. § 150.5(b)(3) (October 15, 2020) (relevant regulation providing that: “For any newly listed commodity

derivative contract subject to paragraph (b) of this section that is substantially the same as an existing contract listed

on a designated contract market or swap execution facility that is a trading facility, the designated contract market or

swap execution facility that is a trading facility listing such newly listed contract shall adopt spot month, individual

month, and all-months-combined speculative position limits comparable to those of the existing contract.”) Here, the

DPL contract has nearly identical deliverable instruments and expiration schedules to those listed by CME Group in

its Bakken DAPL (Argus) Monthly Futures (DAB). Therefore, the Exchange has determined to set spot month

speculative position limits, single and all-months-combined accountability levels at 2,000 contracts for DPL,

identical to those at CME Group. (https://www.cmegroup.com/markets/energy/crude-oil/bakken-dapl-argusmonthly.contractSpecs.html and https://www.cmegroup.com/rulebook/files/position-limits-nymex.xlsx)
