Environmental Compliance at NuStar Energy: Regulations and Costs
This paper examines NuStar Energy L.P.'s operations within the framework of federal and state environmental regulations. It outlines the company's infrastructure, including 9,063 miles of pipeline and 86 terminal facilities, and details the regulatory landscape governing air emissions, water quality, hazardous waste, and pipeline integrity. The paper analyzes NuStar's capital expenditures for environmental compliance ($6.5–6.9 million annually) and contextualizes these costs within broader industrial competitiveness concerns. It also presents an overview of major environmental legislation including the Clean Air Act, Clean Water Act, and CERCLA, concluding that environmental compliance costs remain modest relative to industry benefits and economic gains.

What makes this paper effective
- Provides a concrete case study of a real, major energy company facing actual regulatory obligations, making abstract environmental law tangible and applied.
- Systematically maps multiple regulatory domains (air, water, waste, pipeline safety) without overwhelming the reader, creating a coherent compliance landscape.
- Anchors cost discussion in real numbers ($6.5–6.9 million) and then situates those figures within wider industry data, showing compliance is economically feasible.
- Balances legal/compliance content with economic analysis, addressing genuine business concerns about competitiveness without dismissing regulatory necessity.
Key academic technique demonstrated
The paper employs a regulatory audit structure: identify the company, enumerate applicable laws, explain compliance requirements, assess financial impact, then contextualize within industry benchmarks. This approach is common in business law and environmental policy analysis. Rather than arguing for or against regulation, the paper documents its real-world application, using both primary company sources (annual reports) and peer-reviewed economic research to ground claims.
Structure breakdown
The essay opens with NuStar's profile and operations, then expands outward in concentric circles: first the general regulatory framework, then specific compliance costs, then deep dives into individual law domains (air, water, waste, pipelines), then a capstone section comparing compliance costs to industry benefits. This arrangement moves from particular to general, making the company's constraints intelligible before generalizing to sector-wide economic effects.
Company Overview and Operations
NuStar Energy L.P. is a limited partnership that is publicly traded and headquartered in San Antonio. The company operates an extensive infrastructure comprising 9,063 miles of pipeline, eighty-six terminal facilities, four crude oil storage facilities, and two asphalt refineries. As the second-largest independent liquid terminal operator in the United States, NuStar maintains a global presence with operations in the U.S., Netherlands, Canada, United Kingdom, Antilles, and Mexico. The company's integrated storage infrastructure can hold up to 86 million barrels and includes refineries for asphalt and crude oil, pipelines for refined products, terminals for refined products, petroleum storage facilities, and crude oil storage and terminal operations.
Environmental stewardship is a stated priority for the company. NuStar works to improve its programs and processes to meet stringent environmental standards, resulting in better overall environmental performance. Reportable releases have drastically reduced over the past eight years, demonstrating the company's commitment to environmental responsibility.
Environmental and Safety Regulation Framework
NuStar's operations are controlled by extensive local, state, and federal laws concerning environmental protection. These regulations cover modes of waste disposal, waste management, pollution prevention measures, operator qualifications, and pipeline integrity requirements. Numerous federal and state safety and health regulations apply to the company, including those that ensure pipeline safety.
The primary environmental concerns for NuStar include unauthorized air emissions, releases of waste into soil, groundwater, or surface water, and potential injury to people or damage to property. Compliance with these laws and regulations results in high capital expenditures and increases the overall cost of doing business. Violations of environmental laws or permits can result in heavy criminal and civil liabilities, penalties, and injunctions.
To manage these risks, NuStar has incorporated comprehensive procedures, practices, and policies governing pollution control, pipeline integrity, public education and relations, process safety management, product safety, material handling, and occupational health. These measures are designed to protect pipelines, employees, the public, and the environment while limiting liability from malfunctions or errors. However, future changes or additions to environmental laws could necessitate further capital expenditures and operational costs that cannot be ascertained in advance. Additionally, spills may cause contamination and create unforeseen liabilities, which are inherent risks in the energy transportation and storage industry.
Capital Expenditures for Compliance
NuStar's capital expenditures for environmental compliance totaled $6.9 million in 2012 and decreased slightly to $6.5 million in 2013. These investments reflect the company's ongoing commitment to meeting and exceeding regulatory requirements.
One major driver of these expenditures relates to air quality standards. The Clean Air Act Amendments of 1970 directed the Environmental Protection Agency (EPA) to establish national ambient air quality standards—the minimum air quality that every county is required to meet. The standards apply to four criteria pollutants: tropospheric ozone (O₃), carbon monoxide (CO), total suspended particles (TSPs), and sulfur dioxide (SO₂). Each county in the United States receives attainment or nonattainment designations for each of these four pollutant classes. Nonattainment means that a county has exceeded the EPA's set limit for that pollutant, which triggers more stringent scrutiny of emitters in that county than those in attainment areas. Institutions classified as non-polluters are exempt from many of these laws and regulations.
The increasing stringency of air quality standards creates pressure on companies like NuStar to upgrade equipment and monitoring systems. Companies operating in nonattainment areas face heightened compliance costs due to more rigorous emission controls and reporting requirements. These economic pressures are offset, in part, by the public health and environmental benefits achieved through improved air quality nationwide.
