At IES inc., we specialize in comprehensive environmental engineering
solutions, helping clients achieve sustainable and compliant operations.
Our expertise spans emissions inventories, regulatory consulting,
and environmental impact assessments, ensuring your
business meets all necessary standards efficiently.
Compliance support for operators navigating state mandatory GHG reporting - applicability determinations, source identification, and strategy as rules evolve.
Multi-year compliance support covering facility screening, emissions calculations, annual report preparation, and internal data workflow development.
Facility-specific GHG monitoring plans covering sources, methodologies, measurement devices, QA/QC procedures, and recordkeeping requirements.
Summary memoranda and internal reporting tools for operators managing GHG obligations across multiple facilities and regulatory programs.
Led end-to-end emissions quantification projects beginning with field measurement campaigns and culminating in fully documented GHG reports.
Facility-scale studies comparing remote sensing measurements against source-level inventories to identify discrepancies and improve reporting accuracy.
Designed and validated portable measurement protocols for quantifying emissions from natural gas infrastructure sources.
Designed and built custom high-volume sampler instruments to support field measurement campaigns.
Technical working groups for pipeline operator coalitions — consensus positions, regulatory clarification requests, and member coordination.
Provided written regulatory analyses and formal comment letters to state and federal agencies on proposed rule makings affecting oil and gas operators.
Assisted clients in preparing for and participating in regulatory proceedings, agency meetings, and stakeholder engagement processes.
Designed and implemented LDAR programs for natural gas facilities subject to federal and state leak detection requirements.
Conducted field inspections at natural gas storage and transmission facilities to support compliance verification and emissions data collection.
Conducted AERMOD-based dispersion modeling analyses in support of air permit applications and compliance demonstrations for natural gas and energy facilities.
Provided technical support for air permit applications at natural gas compression, processing, and storage facilities. Work included emissions calculations, applicability determinations, BACT/LAER analyses, and coordination with state permitting agencies.
Participated in the development and field validation of through-valve acoustic leak detection technology designed to identify internal valve leakage in natural gas pipeline systems without requiring pipeline isolation or pressure testing.
Contributed technical expertise to federally sponsored research programs focused on characterizing and reducing methane emissions from natural gas infrastructure.
Developed novel measurement methodologies for quantifying GHG emissions from sources lacking established EPA reference methods.
Whether you're facing a new reporting requirement, planning a field measurement campaign, or navigating a shifting regulatory landscape, the right guidance early on saves time and reduces risk down the road. Schedule a free consultation and let's map out what your next project needs to succeed.
