CONTROL: 332001601074 SUBJECT: Site Reconnaissance: August 19, and October 7, 2011 Scorpio Recycling, Inc. Remedial Investigation/Feasibility Study Toa Baja, Puerto Rico Dear Mr. Bosque: This letter provides a summary of the conditions observed by CDM at the Scorpio Recycling, Inc. (SRI) site on August 19, and October 7, 2011 during site reconnaissance. Photos taken during the visit are included as Attachments A and B. August 19, 2011 Site Observations Attendee: Jose Reyes (CDM Field Technician) Operations: Four people (Mr. Manuel Figueroa, Gloria Rodriguez and two labors) were observed working at the facility picking through scrap. Mr. Figueroa informed CDM that they continue to separate tires from their rims and store them (without decontamination) in the former Aluminum and Copper Brass Building. Equipment at the Site: Bob Cat, Digger and a Track Excavator that appears to be damaged. Southern Area: No active work observed; no change apparent since prior visit with one large vinecovered soil pile and one tire pile. Observation: Some apparent new material was observed inside a warehouse on site. Northern Area: Four soil piles, four large scrap piles, ponding of water along an interior road and near the base of several piles. A subcontracted surveyor marked the Northern Area grid locations; five locations of the grid are pending location due to restricted access to these locations. Central Area: Piles are mostly composed of tires with scrap material in various proportions. Some puddles were observed along the interior dirt roads. New clearings in the area suggest that displacement and/or removal of material had occurred at these areas. Northern Access Road: Up to 2 feet of soil/sediment has accumulated within approximately 20 feet of the access road as a result of a metal obstruction. R2-0001310

October 12, 2011  Mr. Adalberto Bosque Remedial Project Manager U.S. Environmental Protection Agency Caribbean Environmental Protection Division Centro Europa Building, Suite 417 1492 Poncé de Leon Avenue San Juan, Puerto Rico 00907‐4127  PROJECT:  RAC 2 Contract No.: EP‐W‐09‐002 

Work Assignment No.: 016‐RICO‐02HA  DOC. CONTROL:     3320‐016‐01074  SUBJECT:  Site Reconnaissance: August 19, and October 7, 2011   Scorpio Recycling, Inc.   Remedial Investigation/Feasibility Study    Toa Baja, Puerto Rico  Dear Mr. Bosque:  This  letter provides a summary of the conditions observed by CDM at the Scorpio Recycling,  Inc.  (SRI) site on August 19, and October 7, 2011 during  site  reconnaissance. Photos  taken during  the visit are included as Attachments A and B. 

 August 19, 2011 ‐ Site Observations  Attendee: Jose Reyes (CDM Field Technician)  Operations:  Four people  (Mr. Manuel  Figueroa, Gloria Rodriguez  and  two  labors) were observed 

working  at  the  facility  picking  through  scrap. Mr.  Figueroa  informed  CDM  that  they  continue  to separate tires  from their rims and store them  (without decontamination)  in  the  former Aluminum and Copper Brass Building. 

Equipment at the Site:  Bob Cat, Digger and a Track Excavator that appears to be damaged.  Southern Area: No active work observed; no change apparent since prior visit with one  large vine‐

covered soil pile and one tire pile.  Observation: Some apparent new material was observed inside a warehouse on site.   Northern Area: Four soil piles,  four  large scrap piles, ponding of water along an  interior  road and 

near the base of several piles.  A  subcontracted  surveyor marked  the Northern Area grid  locations;  five  locations of  the grid are 

pending location due to restricted access to these locations.  Central Area: Piles are mostly composed of  tires with scrap material  in various proportions. Some 

puddles  were  observed  along  the  interior  dirt  roads.  New  clearings  in  the  area  suggest  that displacement and/or removal of material had occurred at these areas. 

Northern Access Road: Up to 2 feet of soil/sediment has accumulated within approximately 20 feet of the access road as a result of a metal obstruction.

Monitoring Wells: Both MW‐1  and MW‐4A were  in  good  condition,  yet MW‐1 was  covered with mud.  SRI’s  subcontractor  blocked  and  locked  the  northern  access  to  avoid  the  entrance  of trespassers.  

Accessible  Onsite  Structures:  Areas  appear  cleaner  and with  less  trash/debris  than  in  the  past, except  for  the  unused  structure  in  the  Southern  Area  which  remains  filled  with  assorted trash/debris. 

 October 7, 2011 ‐ Site Observations  Attendee: Jose Reyes (CDM Field Technician)  Operations:  Three  people  (Mr. Manuel  Figueroa  and  two  labors) were  observed working  at  the 

facility picking through scrap. Mr. Figueroa informed CDM that they continue to separate tires from their  rims  and  store  them  (without decontamination)  in  the  former Aluminum  and Copper Brass Building. 

Equipment at the Site:  One Digger and a Track Excavator that appears to be damaged.  Southern Area: No active work observed; no change apparent since prior visit with one  large vine‐

covered soil pile and one tire pile.  Observation: Most of the piles are becoming vegetated.   Northern Area: No change.  Central Area: No change.  Northern Access Road: Up to 2 feet of soil/sediment has accumulated within approximately 20 feet 

of the access road as a result of a metal obstruction, and dense vegetation has begun to cover this main accessway. 

Monitoring Wells: MW‐4A and MW‐1 remain in good condition.   Accessible Onsite Structures: No change.  Key Issues in Moving the RI Forward  Current  conditions within  the Northern Area would not  support  implementation of  the proposed 

subsurface  investigation.  Therefore,  CDM  and  EPA  have  established  an  alternative  approach  for completing the field investigation, including the excavation of test pits at each boring site to confirm the  absence  of  utilities.  Shallow  soil  samples  will  be  collected  while  the  excavation  is  open. Composite  characterization  samples  will  be  collected  from  within  the  soil/scrap  stockpiles  to characterize material  expected  to  be  removed  during  remedial  action  and  inform  the  feasibility study. 

Eliminate  potential  recontamination:  Via  enforcement,  such  that  no  portion  of  the  site  that  is cleared and/or investigated is re‐inhabited by scrap/waste/operations. 

Establish  site  controls:  It  is  critical  that  (1)  PRP  establish  physical  controls  at  SRI  to  eliminate potential migration of contaminants offsite or to areas  investigated to date, and  (2) PRP eliminate further  damage  to  existing  site  wells  and  any  other  project‐related  installations  due  to  SRI operations. Any plan developed/implemented by SRI  to control  the site perimeter with respect  to potential contaminant migration should be provided to CDM. 

 Schedule  CDM and EPA expect to begin final field investigation activities by October 31, 2011.
