In 1987, Mr. Piazza was named President of the Operational Forecast Division, in 1991, Executive Vice President of the Company and in 2001, President and CEO. In addition to his administrative responsibilities as President, he is a Certified Consulting Meteorologist holding Certificate #661.

The experts at Minnich and Scotto, Inc. are Meteorologists – each with 40+ years' experience in providing a wide range of ambient air-related and meteorological services to attorneys, local communities, industry, and government.  

Litigation Support - Established in 1996, their business has evolved over the years based on changing client needs – originally providing predominantly high-end, “boutique” consulting services to industry and government (such as real-time, emission-rate measurements of airborne toxins from hazardous waste sites and other large area sources), and today offering a variety of technical services to environmental attorneys in support of toxic tort cases, including reconstructive analyses to assess past exposure to hazardous air pollutants (HAP) and other air toxins.

Minnich and Scotto's unique skill set – owing to a high level of proficiency in diverse disciplines such as ambient air monitoring, air dispersion modeling, CERCLA (Superfund) and Clean Air Act regulations, forensic meteorology, and environmental quality assurance – has often led to development of winning legal strategies for our attorney clients which otherwise might not have been envisioned. They have extensive knowledge in the following areas:

Regulatory:

• CERCLA and Clean Air Act Compliance

Ambient Air Monitoring and Sampling: Strategy and Design Technology Selection Analysis Techniques

Air Dispersion Modeling: Strategy and Design Model Selection and Execution Model Calibration / Validation

HAP Emission Investigations: Real-Time Emission-Rate Assessments Exposure Assessments and Reconstructions

Meteorological Consulting: Chemical Accidents Reconstruction Toxicology Investigative Support

Quality Assurance: 

• DQO Process Compliance
• Monitoring / Sampling Plan Assessment

Timothy R. Minnich, President, MS, QEP, is a Meteorologist and Atmospheric Scientist with over 40 years experience in the design and management of a wide range of ambient air and meteorological investigations under CERCLA and the Clean Air Act. He is a recognized technical expert on high-profile legal cases, with assignments involving forensic meteorology and reconstruction of inhalation scenarios in relation to community exposure to hazardous air pollutants (HAP). 

Mr. Minnich is accomplished in presenting conclusions and opinions derived from analysis of complex technical data in a well-reasoned and easily understood manner. He is a skilled technical writer and proven manager in a highly specialized arena. He is a nationally recognized expert in the application of optical remote sensing (ORS) for hazardous waste site remediation. He has designed and managed more than 25 ORS field investigations and air dispersion model validation studies since the promulgation of U.S.EPA (EPA) Method TO-16 for open-path FTIR (Fourier-transform infrared) spectroscopy in 1988. 

Mr. Minnich was an instructor for several half-day continuing education courses on calculating emission rates from ground-level sources.

Robert L. Scotto is a Meteorologist with over 40 years of experience in the design, management, and execution of a variety of air quality investigations. He is a specialist in Clean Air Act permitting, and is an expert in a broad range of CERCLA-related QA/QC issues.
