What's New

Hospitals operate like small cities. On any given day, they manage hazardous waste and pharmaceutical waste, generator air permitting, wastewater considerations, chemical storage, oil management, and emergency reporting. All of this happens while supporting patient care around the clock.

At ONE Environmental Group, we help hospital systems bring structure, consistency, and confidence to environmental compliance across facilities. Our work is designed to reduce risk, support operations, and make compliance manageable for internal teams.

Healthcare Compliance is Multimedia by Nature

Hospital environmental compliance is rarely limited to a single program. Many healthcare organizations must coordinate requirements across air, stormwater, wastewater, hazardous waste, pharmaceutical waste, community right-to-know reporting, and Spill Prevention, Control, and Countermeasure (SPCC) planning. That complexity increases quickly when a system includes multiple hospitals, different permitting histories, and evolving infrastructure.

ONE helps hospitals take a system-wide view, so requirements are understood, managed, and sustained across locations.

A System-Wide Approach Starts with Knowing Where You Stand

For multi-facility healthcare systems, one of the biggest challenges is simply establishing a clear baseline.

• Which permits apply at each site
• What reporting obligations exist
• Where deadlines and renewals are coming up
• What gaps create the most risk

We begin by compiling available regulatory information and building a compliance snapshot that provides leadership and environmental, health and safety (EHS) teams with clarity on the current state and the most urgent needs.

We Validate Compliance Where It Matters Most

Hospitals are high-intensity operating environments. Compliance programs need to reflect the realities of day-to-day operations and staff turnover.

We conduct on-site walkthroughs of key areas such as laboratories, pharmacies, waste accumulation locations, chemical storage rooms, maintenance shops, and generator areas. This allows us to confirm whether what is required is aligned with what is happening in practice and identify opportunities to strengthen consistency and reduce exposure.

Hospitals Need Priorities and Practical Tools

A long list of issues is not helpful if it does not come with priorities and a path forward.

The ONE team delivers clear, ranked action plans that help teams focus on what matters most first. We also provide tools that support execution and accountability, such as compliance calendars, responsibility assignments, recordkeeping trackers, training support, and waste program improvements aligned with current regulations.

The Bottom Line

Hospitals do not need another compliance report. They need an approach that works across facilities and supports real operations.

ONE helps healthcare systems build scalable environmental compliance programs that strengthen performance, reduce risk, and support patient-focused operations. Contact us today if your hospital system is expanding, modernizing facilities, or looking to bring consistency across sites. We would welcome the chance to support your team.

Outside of work, Kailee has been practicing Jiu-Jitsu for more than three years. She also enjoys video games and playing chess.

What Kailee enjoys most about working at ONE is the team environment and the culture of the Charlotte office. She values the mix of routine and variety in her work, as well as the opportunity to grow alongside supportive colleagues.

As the calendar turns, many organizations are shifting focus from day-to-day operations to a critical part of environmental compliance: annual and recurring regulatory reporting. Several key federal and state environmental reports tied to calendar year 2025 activities are due in 2026, and early preparation can help avoid last-minute stress, reporting errors, and potential enforcement issues.

Below is a summary of some of the key requirements and what companies need to know:

EPCRA Tier II Reporting – Due March 1, 2026 – Under Section 312 of the Emergency Planning and Community Right-to-Know Act (EPCRA), facilities may be required to submit Tier II chemical inventory reports if they stored hazardous chemicals on-site during 2025. In general, Tier II reporting applies to facilities that stored 10,000 pounds or more of a hazardous chemical at any one time during the year, or Extremely Hazardous Substances (EHSs) at or above their lower regulatory thresholds.

RCRA Biennial Hazardous Waste Reporting – Due March 1, 2026 – Facilities classified as Large Quantity Generators (LQGs) must submit a biennial hazardous waste report covering calendar year 2025. This report summarizes hazardous waste generation, management, and disposal activities.

Annual Air Updates and Emissions Statements – Due March 1, April 15, or June 30, 2026 – Air compliance reporting timelines vary depending on permit type and jurisdiction. Many facilities are required to submit annual updates, emissions statements, or operational summaries. Permit conditions should be reviewed carefully to confirm applicable deadlines.

Title V Semi-Annual Reports – Typically Due End of January and End of July – Facilities operating under Title V air permits are generally required to submit semi-annual monitoring or deviation reports summarizing compliance status.

Title V Annual Compliance Certification – Due March 1, 2026 – Title V sources must also submit an annual compliance certification certifying compliance with all applicable permit conditions for calendar year 2025.

Toxics Release Inventory (TRI) Reporting – Due July 1, 2026 – TRI reporting under Section 313 of EPCRA applies to facilities in covered industry sectors that exceed employee thresholds and manufacture, process, or otherwise use listed TRI chemicals above regulatory thresholds during 2025.

Plan Ahead to Stay Compliant

Environmental reporting requirements continue to grow more complex. Reviewing inventories, waste records, air emissions data, and permit conditions early can help ensure accurate and timely submittals.

ONE Environmental Group is here to help, with regional teams of experienced consultants who can:

• Assess your reporting requirements to ensure accuracy.
• Help you gather and organize the necessary data.
• Complete and submit reports on your behalf to meet deadlines.

GIS Analyst

Jenna Mayfield joined ONE Environmental Group in August 2025, bringing with her a rare blend of technical skill, creative perspective and genuine enthusiasm for geospatial problem-solving. Today, she serves as a GIS Analyst based out of ONE’s Charlotte office, applying her deep knowledge of mapping, data visualization and environmental science to support clients and teams across the company.

Raised in Mooresville, North Carolina — a place she still calls home — Jenna’s path into environmental GIS work began at the University of North Carolina at Chapel Hill. There, she earned dual bachelor’s degrees in Environmental Science and Information Science & Technology, along with a minor in Geographic Information Systems. She built a strong foundation in tools like ArcGIS Pro, QGIS, Python and remote sensing workflows, complementing her hands-on field experience with drone mapping, LiDAR and machine learning applications.

Before joining ONE, Jenna gained experience through several research-driven, conservation-focused positions. She supported The Nature Conservancy by using drone and camera imagery to assess pollinator habitats at solar facilities. She contributed to coastal and flood resiliency research for the North Carolina Collaboratory — work that helped shape policy papers shared with state leaders.
