Leak Detection and Repair (LDAR) is no longer a niche compliance service, it’s a critical part of environmental performance, regulatory compliance, and reputational risk management for oil and gas operators.

From newly constructed gas plants to aging compressor stations and well pads, facilities across the oil and gas value chain face growing pressure to detect, report, and repair fugitive emissions.

For operators that lack in-house LDAR capabilities, or even for those with internal teams, Encino Environmental Services (Encino) provides a full-service, expert-driven solution tailored to regulatory obligations and facility needs.

The Problem LDAR Solves

LDAR requirements are designed to reduce emissions of volatile organic compounds (VOCs) and greenhouse gases from equipment leaks, a major contributor to air pollution. The need for LDAR is largely regulatory — shaped by the Clean Air Act and reinforced by state-level mandates and local air district rules. Facilities can additionally find themselves subject to federal rules such as:

• Method 21 (40 CFR Part 60, Appendix A)
• NSPS Subparts KKK, VVa, OOOOa (Quad OA), and OOOOb (Quad OB)
• GHG Monitoring Regulations (GHGRP Subpart W)

These regulations apply differently depending on the facility’s type, location, and emissions potential.  Additionally, some facilities can be subject to LDAR requirements from their air permits. Operators must not only detect and quantify leaks — they must also perform timely repairs and maintain detailed records for audits and enforcement.

Who Needs LDAR Services?

Encino serves a wide variety of facilities in both attainment and nonattainment zones, including:

• Natural gas processing plants
• Compressor stations
• Well pads and production sites
• Refineries and terminals
• Midstream gathering infrastructure

In many cases, operators do not have the internal resources to manage LDAR. They may lack:

1. Regulatory expertise – Understanding which LDAR programs apply and how to comply.
2. Trained personnel – Performing surveys and managing compliance tasks.
3. Capital investment – High-end equipment like Optical Gas Imaging (OGI) cameras can cost six figures.
4. Repair support – Knowing when and how to conduct compliant repairs within regulatory timelines.

Whether you have no LDAR program or an overwhelmed internal team, Encino fills the gap with a proven, experienced solution.

Encino’s LDAR Services

Encino provides comprehensive LDAR services across all major regulatory frameworks:

1. Optical Gas Imaging (OGI)

Used primarily for Quad OA and OB compliance, Encino’s certified technicians use state-of-the-art OGI cameras to identify emissions sources. OGI is also central to modern voluntary programs like Oil and Gas Methane Partnership (OGMP 2.0).

2. Method 21 Surveys

Though many facilities are moving toward OGI, Method 21 remains mandatory for certain permits and facilities. Encino’s trained technicians conduct Method 21 surveys using flame ionization or photoionization detectors.

3. Rod Packing Surveys on Compressors

Using high-volume samplers, Encino assesses emissions from rod packing on reciprocating compression and dry and wet seal on centrifugal compressors, critical for midstream and processing assets.

4. Greenhouse Gas Emissions Monitoring

For facilities reporting under the EPA’s Greenhouse Gas Reporting Program (GHGRP), Encino provides the combined OGI and quantitative sampling services needed for compliance.

5. Quantitative OGI for OGMP 2.0

Encino supports operators participating in voluntary methane initiatives like OGMP 2.0. We’ve helped clients achieve Level 4 and Level 5 compliance by integrating OGI with quantification tools and robust emissions data analysis.
