Introduction: Bloomington’s Energy Future
Bloomington, Illinois, is a city that blends historic charm with modern growth. As McLean County’s economic center, Bloomington is home to thriving businesses, residential communities, and essential services—all powered by reliable energy infrastructure. Natural gas plays a critical role in this system, but it comes with one surprising fact: natural gas is naturally odorless.
Without intervention, a gas leak could go undetected until it becomes a serious hazard. That’s why odorization—the process of adding a distinct smell to natural gas—is a cornerstone of pipeline safety. In this article, we’ll explore why odorization matters, how pipeline pickling prevents odor fade, and why Burgess Pipeline Services is the trusted partner for utilities in Bloomington.
The Silent Risk of Odorless Gas
Natural gas is primarily methane, which has no color and no smell. While this makes it efficient as a fuel, it also means leaks are invisible and undetectable without specialized measures. To solve this, gas companies add odorants—usually sulfur-based compounds called mercaptans—to the gas stream. These chemicals create the familiar “rotten egg” smell associated with natural gas leaks.
This simple addition saves lives. Federal regulations require odorization so that gas is detectable at concentrations far below explosive limits. Odorization is not optional—it’s a critical safety standard.
Odorization Systems: Technology and Compliance
Adding odorant to natural gas is not as simple as pouring a chemical into a pipeline. It requires precision-engineered systems designed for safety and efficiency. These systems include:
Odorant Storage Tanks: Built for durability and equipped with secondary containment to prevent leaks.
Injection Systems: Technologies like wick odorizers, bypass systems, and drip odorizers ensure consistent odorization.
Monitoring and Compliance: Advanced sensors and controllers maintain compliance with federal standards, even during low-flow conditions.
These systems are designed to meet or exceed regulatory requirements, including 49 CFR 192.625, which governs odorization of gas in the United States.
Pipeline Pickling: Eliminating Odor Fade Before It Starts
Before a new pipeline is commissioned, it undergoes pickling, a conditioning process that removes oxygen, moisture, and contaminants. This step is critical for preventing corrosion and stabilizing odorant levels. Without pickling, pipelines can experience odor fade, where odorant absorbs into the pipe walls, reducing its effectiveness.
Why does odor fade happen?
Steel pipelines can absorb sulfur compounds, especially when they’re new or have residual moisture. Pickling creates a protective environment inside the pipeline, ensuring odorant remains effective from day one.
Benefits of Pickling:
Extends pipeline life.
Prevents odor fade.
Improves operational efficiency.
Local Challenges and Environmental Considerations
Bloomington’s climate and geography present unique challenges for natural gas operations. Seasonal temperature swings can affect gas flow and odorant dispersion. Additionally, environmental regulations in Illinois require strict adherence to safety and containment standards.
The proximity to McLean County’s agricultural and industrial zones underscores the importance of environmental stewardship. Burgess Pipeline Services ensures that odorant tanks and containment systems meet or exceed compliance requirements, protecting both people and natural resources.

Extended FAQs
Q: What makes natural gas smell?
A: Mercaptans added during odorization.
Q: Why does natural gas smell like rotten eggs?
A: The odor comes from sulfur compounds used as odorants.
Q: What is pipeline pickling?
A: A process that removes contaminants and stabilizes odorant levels before pipeline commissioning.
Q: Can odor fade happen in cold climates?
A: Yes, and pickling helps prevent it.
Q: Is methane odorless?
A: Yes, methane has no smell.
Q: How much odorant is added to natural gas?
A: Enough to detect leaks at one-fifth the lower explosive limit.
Q: What happens if odor fade occurs?
A: Leak detection becomes unreliable, increasing safety risks.
Q: Does natural gas have a color?
A: No, it’s colorless and odorless without additives.
Q: Why is mercaptan used?
A: It provides a strong, distinctive odor for safety.
Q: How does Burgess prevent odor fade?
A: Through advanced pickling and conditioning processes.
Q: What is the federal regulation for odorization?
A: 49 CFR 192.625 governs odorization of gas.
Q: Does odorization affect gas quality?
A: No, it only adds a detectable smell for safety.
Q: What is secondary containment for odorant tanks?
A: A safety feature that prevents leaks from reaching the environment.
