The Reynolds Group performed 32 Phase I Environmental Site Assessments and Priority Ranking Studies in the country of Mexico. The engagement required rapidly accessing critical environmental information, performing site inspections around the country, interviewing key personnel, and providing an immediate priority ranking of potential environmental concerns. These concerns were identified at the 32 manufacturing plants that were involved in a highly confidential acquisition. The engagement dealt with heavy industrial manufacturing sites, some of which were two miles square in area. TRG was able to mobilize to ten different states in Mexico and rapidly access critical environmental information by performing site inspections and interviewing key personnel. With this information, TRG provided the Client with frequent updates and finally a priority ranking of the 32 manufacturing plants. TRG coordinated with the fast-moving Fortune 500 client, conducting extensive research and interviews to acquire difficult to obtain information for a large number of sites. At the completion of the project, TRG completed a summary of the findings in an eye chart, a user-friendly format that highlighted the risks and environmental concerns at each site. TRG has maintained a presence in Mexico for nearly 12 years and performs more than 300 due diligence studies per year.
