Permit Number: IL-115-6A-0002 Page F1 of 14

ATTACHMENT F: EMERGENCY AND REMEDIAL RESPONSE PLAN 

This plan is provided to meet the requirements of 40 CFR 146.94. As steps to prevent 

unexpected carbon dioxide (CO2) movement have already been undertaken in accordance with a 

risk analysis and under an injection well permit issued by Illinois Environmental Protection 

Agency (IEPA Permit No.: UIC-012-ADM), this plan is about actions to be taken, and to be 

prepared to take, if unexpected movement or any other emergency events occur at the CCS#1 

Illinois Basin-Decatur Project (IBDP). 

Facility Name: Archer Daniels Midland, CCS#1 Well 

IL-115-6A-0002

Facility Contacts: A site-specific list of facility contacts will be developed and maintained 

during the life of the project. 

Injection Well Location: Decatur, Macon County, Illinois 

39° 52’ 37.06469” N, 88° 53’ 36.25685” W 

This emergency and remedial response plan (ERRP) describes actions that the owner/operator 

(ADM) shall take to address movement of the injection fluid or formation fluids in a manner that 

may endanger an underground source of drinking water (USDW) during Class VI activities, 

including post-injection site care, for the IBDP CCS#1 well. 

The CCS#1 well is related to CCS#2. Delineation of the area of review (AoR) for CCS#1 

incorporates injection activities at CCS#2 (i.e., the two wells will create a single CO2 plume and 

pressure front). Therefore, an emergency event related to either well will require a coordinated 

response. 

If ADM obtains evidence that the injected CO2 stream and/or associated pressure front may 

cause an endangerment to a USDW, ADM must perform the following actions: 

1. Take all steps reasonably necessary to identify and characterize any release. 

2. Notify the permitting agency (UIC Program Director) of the emergency event within 24 

hours. 

3. Implement applicable portions of the approved ERRP. 

Part 1: Local Resources and Infrastructure 

Resources in the vicinity of the IBDP CCS#1 well that may be impacted as a result of an 

emergency event at the project site include: USDWs; potable water wells; the Sangamon River; 

Bois Du Sangamon Nature Preserve; and Lake Decatur. 

Infrastructure in the vicinity of the IBDP CCS#1 well that may be impacted as a result of an 

emergency at the project site include: the wellhead; Richland Community College structures; 

Heartland Community Church; residential areas; commercial properties; recreational facilities; 

and ADM facilities. A map of the local area is provided as Figure F-2 at the end of this plan.

Part 2: Potential Risk Scenarios 

The following events related to the IBDP CCS#1 well could potentially result in an emergency 

response: 

 Well integrity failure at CCS#1 or a monitoring well; 

 A natural disaster (e.g., earthquake, tornado, lightning strike); 

 Fluid (e.g. brine) or CO2 leakage to a USDW or land surface; or 

 Induced seismic event. 

Response actions will depend on the severity of the event(s) triggering an emergency response. 

“Emergency events” are categorized as follows: 

TABLE F-1. DEGREES OF RISK FOR EMERGENCY EVENTS

Emergency Condition Definition

Major Emergency Event poses immediate substantial risk to human health, 

resources, or infrastructure. Emergency actions involving 

local authorities (evacuation or isolation of areas) should be 

initiated.

Serious Emergency Event poses potential serious (or significant) near term risk to 

human health, resources, or infrastructure if conditions 

worsen or no response actions taken. 

Minor Emergency Event poses no immediate risk to human health, resources, or 

infrastructure.

Part 3: Emergency Identification and Response Actions 

Steps to identify, characterize, and respond to the event will be dependent on the specific issue 

identified, and the severity of the event. The potential risk scenarios identified in Part 2 are 

detailed below. 

In the event of an emergency requiring outside assistance, the project contact lead shall call 

the ADM Security Dispatch at (217) 424-4444 and ADM Corporate Communications at 

(217) 424-5413.

available, within 24 hours of notification. 

 For all Emergencies (Major, Serious, or Minor): 

o Shut in well (close flow valve), if applicable. 

o Vent CO2 from surface facilities, if applicable. 

o Collect confirmation sample(s) of groundwater and analyze for indicator 

parameters (a list of potential indictors is listed in Attachment E, the PostInjection Site Care and Site Closure Plan, Table 3). 

o If the presence of indicator parameters is confirmed, develop (in consultation 

with the UIC Program Director) a case-specific work plan to: 

 Install additional groundwater monitoring points near the impacted 

groundwater well(s) to delineate the extent of impact, and 

 Remediate unacceptable impacts to the impacted USDW. 

o Arrange for an alternate potable water supply, if the USDW was being utilized 

and has been caused to exceed drinking water standards. 

o Proceed with efforts to remediate USDWs to mitigate any unsafe conditions 

(e.g., install system to intercept/extract brine or CO2 or “pump and treat” to 

aerate CO2-laden water). 

o Continue groundwater remediation and monitoring on a frequent basis 

(frequency to be determined by ADM and the UIC Program Director) until 

unacceptable adverse USDW impact has been fully addressed.

Induced Seismic Event. Induced seismic events typically refer to minor seismic events that are 

caused by human activity which alter the stresses and fluid pressures in the earth's crust. Induced 

seismicity could potentially result from the injection of fluids into subsurface formations that 

lubricate and/or change the stress state of pre-existing faults which causes fault plane movement 

and energy release. Most induced seismic events are extremely small (microseismic) but in 

some instances are great enough to be felt by humans. Case histories of induced seismic events 

associated with fluid disposal wells show seismic events as far away as about 10 to 12 km (6.2 to 

7.4 miles). Based on the project operating conditions, it is highly unlikely that injection 

operations would ever induce a seismic event outside an eight (8) mile radius from the wellhead. 

Therefore this portion of the response plan is developed for any seismic event with an epicenter 

within an eight (8) mile radius of the injection well. 

To monitor the area for seismicity, the site has installed five (5) surface seismic monitoring 

stations and three (3) borehole monitoring stations that continuously record the site’s seismic 

activity. In addition to these stations, the USGS has deployed a network of nine (9) surface 

seismic monitoring stations and three (3) borehole monitoring stations. Based on the periodic 

analysis of the monitoring data, observed level of seismic activity, and local reporting of felt 

events, the site will be assigned an operating state. The operating state is determined using 

threshold criteria which correspond to the site’s potential risk and level of seismic activity. The 

operating state provides operating personnel information about the potential risk of further 

seismic activity and guides them through a series of response actions. In the following table the 

ADM Decatur Seismic Monitoring System is presented. The table corresponds each level of 

operating status with the threshold conditions and operational response actions.
