Michigan Clean Air Act for Energy/Utilities: A Cybersecurity Perspective

 

While Michigan follows the federal Clean Air Act, the state has its own implementation through Michigan's Natural Resources and Environmental Protection Act (NREPA), specifically Part 55, Air Pollution Control. For energy and utility companies operating in Michigan, this creates unique cybersecurity considerations.

 

Key Components of Michigan's Clean Air Regulations for Energy/Utilities

 

• Michigan Air Emissions Reporting System (MAERS) - A digital platform where utilities must report emissions data that requires secure access controls and data integrity protections
• Renewable Operating Permits (ROP) - Digital permit management for major sources of air pollution with sensitive compliance information that must be protected
• Michigan Mercury Rule - Stricter than federal standards, requiring detailed emissions monitoring and reporting systems that must be secured against tampering
• Michigan Air Pollution Control Rules - State-specific regulations that require automated monitoring systems which are potential attack vectors

 

Cybersecurity Risks Specific to Michigan Utilities Under Clean Air Regulations

 

• Continuous Emissions Monitoring Systems (CEMS) - Required for Michigan power plants, these internet-connected systems could be compromised to falsify emissions data or disrupt operations
• Industrial Control Systems (ICS) - Systems that control emissions reduction equipment are vulnerable to attacks that could cause environmental violations
• MAERS Database Vulnerabilities - Michigan's centralized emissions reporting database contains sensitive operational data attractive to competitors or bad actors
• Regional Transmission Organizations - Michigan utilities connected to MISO (Midcontinent Independent System Operator) face unique integration points between emissions monitoring and grid operations

 

Michigan-Specific Compliance Requirements

 

• Michigan Department of Environment, Great Lakes, and Energy (EGLE) - Requires secure digital submission of quarterly emissions reports that must maintain data integrity
• Michigan Electric Provider Renewable Energy Standard - Requires tracking and reporting of renewable energy credits through digital systems that must be secured
• Michigan Carbon Dioxide Budget Trading Program - Creates requirements for secure emissions allowance tracking systems
• Michigan Public Service Commission (MPSC) Regulations - Oversees integrated resource planning with sensitive operational data that must be protected

 

Common Attack Vectors for Michigan Utility Clean Air Systems

 

• SCADA System Infiltration - Attackers may target the control systems for emissions control equipment to cause violations
• Data Tampering - Manipulation of emissions data before submission to MAERS to hide violations or disrupt operations
• Credential Theft - Targeting login credentials for Michigan's EGLE reporting platforms
• Supply Chain Attacks - Compromising vendors who service emissions monitoring equipment at Michigan facilities
• Ransomware - Encrypting emissions data right before Michigan's quarterly reporting deadlines to force ransom payments

 

Essential Cybersecurity Measures for Michigan Clean Air Compliance

 

• Air Quality Monitoring Network Security - Implement encryption and access controls for all monitoring equipment reporting to Michigan EGLE
• MAERS Submission Verification - Use digital signatures and multi-factor authentication when submitting reports to Michigan's system
• Segmentation of Control Networks - Isolate emissions control systems from general business networks to prevent lateral movement by attackers
• Backup Monitoring Systems - Maintain redundant systems to ensure continuous compliance with Michigan's continuous monitoring requirements
• Incident Response Planning - Develop specific procedures for responding to attacks on emissions monitoring systems that include notification to Michigan EGLE

 

Regulatory Reporting Requirements During Cybersecurity Incidents

 

• Michigan EGLE Notification - Required within 24 hours if cybersecurity incidents impact emissions monitoring capabilities
• MPSC Reporting - May require notification if incidents affect critical utility infrastructure
• Data Backup Requirements - Michigan regulations require utilities to maintain verifiable backups of emissions data
• Alternative Monitoring Plans - Need to be filed with Michigan EGLE if primary monitoring systems are compromised

 

Practical Security Measures for Non-Technical Staff

 

• Recognize Phishing Attempts - Train staff to identify emails attempting to steal MAERS or EGLE portal credentials
• Report Unusual System Behavior - Establish clear protocols for reporting anomalies in emissions monitoring equipment
• Secure Remote Access - Use VPNs and multi-factor authentication when accessing Michigan reporting systems remotely
• Document Chain of Custody - Maintain records of who accesses and modifies emissions data before submission
• Regular Training Updates - Keep staff informed of evolving Michigan regulatory requirements and associated security protocols

 

Michigan-Specific Resources and Contacts

 

• Michigan EGLE Air Quality Division - Primary contact for reporting cybersecurity incidents affecting Clean Air Act compliance
• Michigan Cyber Civilian Corps (MiC3) - Volunteer cybersecurity experts who can assist during major incidents
• Michigan Intelligence Operations Center (MIOC) - Can provide threat intelligence specific to critical infrastructure in Michigan
• Michigan Public Service Commission Critical Infrastructure Protection - Offers guidance on protecting utility systems
