1.0 INTRODUCTION 

1.1 Overview 

Energy Answers Arecibo, LLC (Energy Answers or the applicant) proposes to a construct a waste-toenergy (WTE) generation and resource recovery facility in the Cambalache Ward of Arecibo, Puerto Rico,

and may request financial assistance from the United States Department of Agriculture (USDA) Rural 

Utilities Service (RUS) for the project. Energy Answers has stated that it may request a loan from RUS.

RUS has determined that the agency’s decision to finance the proposed project would constitute a 

major federal action that may have a significant impact upon the environment within the context of the 

National Environmental Policy Act of 1969 (NEPA) and has also determined that an Environmental 

Impact Statement (EIS) is the appropriate level of environmental review. Prior to making a decision on 

Energy Answers’ request, RUS must consider possible environmental impacts of the proposed project.

RUS will use the NEPA planning process to encourage agency and public involvement in the review of 

the proposed project and to identify the range of reasonable alternatives.

The EIS will be prepared in accordance with the Council on Environmental Quality’s regulations for 

implementing NEPA (40 CFR Parts 1500–1508), and RUS’ Environmental and Policies and Procedures 

(7 CFR Part 1794). RUS is the lead federal agency, as defined at 40 CFR 1501.5, for preparation of the EIS.

In addition, as part of its broad environmental review process, RUS must take into account the effect of

the proposal on historic properties in accordance with Section 106 of the National Historic Preservation

Act (Section 106) and its implementing regulation, ‘‘Protection of Historic Properties’’ (36 CFR part 800).

Pursuant to 36 CFR 800.2(d)(3), RUS is using its procedures for public involvement under NEPA to meet

its responsibilities to solicit and consider the views of the public during the Section 106 review.

Among the alternatives that RUS will address in the EIS is the No Action alternative, under which the

proposal would not be undertaken. In the EIS, the effects of the proposal will be compared to the

existing conditions in the proposal area. Public health and safety, environmental impacts, and

engineering aspects of the proposal will be considered in the EIS.

Any final action by RUS related to the proposal will be subject to, and contingent upon, compliance with

all relevant executive orders and federal, state, and local environmental laws and regulations in addition

to the completion of the environmental review requirements as prescribed in RUS’ Environmental

Policies and Procedures, 7 CFR Part 1794, as amended.

1.2 Public Outreach 

On April 12, 2013, RUS published in the Federal Register a Notice of Intent (NOI) to Prepare a 

Supplemental Final EIS (SFEIS) in connection with potential impacts related to the proposal by Energy 

Answers (78 FR 21908). In accordance with 7 CFR 1794.74 and 40 CFR 1502.21, RUS intended to 

incorporate by reference the 2010 environmental impact analyses and documentation prepared by the 

Puerto Rico Industrial Development Company (PRIDCO). PRIDCO served as a lead agency in preparation 

of an EIS prepared under the Puerto Rico Environmental Public Policy Act, Article 4(B)(3), (Law No. 416, 

September 22, 2004). The EIS is referred to as the PRIDCO EIS in this scoping report.
Arecibo Waste-to-Energy Project Scoping Summary Report

According to the April 12, 2013, NOI, the SFEIS was scheduled for publication in March 2013 and the 

public was invited to submit comments on the proposal to prepare an SFEIS, to inform RUS decisionmaking in its environmental review process.

On November 28, 2014, RUS published in the Federal Register a Notice of Cancellation of the SFEIS and 

Notice of Public Scoping and Intent to Prepare an Environmental Impact Statement (79 FR 70846).

Through this notice, RUS announced that it was cancelling its NOI for the SFEIS and announced its intent

to conduct public scoping and prepare an EIS. The public was invited to submit comments concerning 

the public scoping, the NOI, or to participate as a ‘‘consulting party’’ under Section 106. These 

comments were to be submitted to RUS on or before December 29, 2014.

On January 14, 2015, following the closing of the comment period, RUS published in the Federal Register

a Notice of Extension of Public Comment Period, Notice of Public Scoping Meeting and Intent to Prepare 

an Environmental Impact Statement (80 FR 1892). Through this notice, RUS extended the comment 

period by an additional 30 days from the date of the notice to February 13, 2015. The notice also 

announced that a public scoping meeting would be held on January 28, 2015, from 3:00– 7:00 p.m. at 

the Colegio de Ingenieros y Agrimensores de Puerto Rico, Capıtulo de Arecibo, Ave. Manuel T. Guillan 1,

Arecibo. Project-related information was available at RUS’ web site (http://www.rurdev.usda.gov/ UWPAreciboPuertoRico.html) and at the Tribunal General de Justicia, Centro Judicial, and the Casa Alcaldıa 

del Municipio de Arecibo.

In addition, individuals who contacted RUS were provided with information on the date and format of 

the proposed public scoping meeting. Copies of the Federal Register notices are provided in Appendix A. 

Appendix B contains copies of the newspaper notices and affidavits.

The public scoping meeting was conducted in an open house format with a court reporter available for 

transcription of verbal comments. The meeting provided the public with the opportunity to learn more 

about the proposed project and to provide comments on potential environmental issues associated with 

the project. Overall, 134 attendees registered on the sign in sheets (see Appendix C). Additionally, 38 

members of the public signed up to provide verbal statements, and 34 people gave verbal comments at 

the meeting; their comments were transcribed by court stenographer. The transcript is provided in 

Appendix D. There were 46 written comments submitted at the meeting using the comments sheets 

provided, and an additional 4 prepared comments were submitted at the meeting, including comments 

from the Puerto Rico Mayor’s Association. Those, along with the comments received via other avenues 

during the 2014 and 2015 scoping periods are provided in Appendix E.

In general, the following concerns were expressed during the public scoping meeting:

• The meeting attendees were upset with the government of Puerto Rico review and approval 

process of the 2010 PRIDCO EIS and expressed that the proposed project was rushed through 

without adequate oversight.

• The attendees stated that the air emissions permit issued by the United States Environmental 

Protection Agency (USEPA) did not adequately protect the health of the community. Particular 

concerns were expressed with emissions of lead and a high incidence of childhood lead 

poisoning in the area. Concerns were also expressed that the air dispersion modeling was 

inadequate and did not use proper data and assumptions.

• Commenters expressed concern that the applicant’s health and safety risk assessment was 

inadequate and sufficient documentation or explanation was not provided to allow for the 

community to evaluate the results of the analysis. 

• Comments were expressed that the project will prevent or discourage the recycling of municipal 

solid waste.

• The public expressed concerns that the format of the scoping meeting was not conducive to 

people providing comments because they were used to the format of public hearings.

• The public expressed concerns about the public notifications for the RUS scoping meeting and 

the lack of explanation of its purpose.

In addition to the comments received during the scoping meeting, RUS received scoping comments in 

the form of written letters or emails from private citizens, government agencies, and nongovernmental 

organizations during the 2014 and 2015 public scoping comment periods. Copies of comment letters 

and written materials submitted for the record during the two scoping periods are included in Appendix 

E to this report and are also available at: http://www.rd.usda.gov/publications/environmentalstudies/impact-statements/arecibo-waste-energy-generation-and-resource. Overall, 160 individuals 

provided comments related to the proposed project during the scoping period with 21 individuals 

contributing via multiple pathways (e.g., a verbal comment and written comment). 

RUS’ Draft EIS (DEIS) will also contain a subsection that summarizes the comments received during the

scoping period.

1.3 Public Scoping Timeline 

The following timeline summarizes the scoping period events:

April 12, 2013 RUS issued a Federal Register NOI to prepare an SFEIS (78 FR 21908).

November 28, 2014 RUS published in the Federal Register, a Notice of Cancellation of the 

SFEIS and Notice of Public Scoping and Intent to Prepare an EIS (79 FR 

70846).

January 14, 2015 RUS published, in the Federal Register, a Notice of Extension of Public 

Comment Period, Notice of Public Scoping Meeting and Intent to 

Prepare an EIS (80 FR 1892).

January 28, 2015 RUS held a public scoping meeting at the Colegio de Ingenieros y 

Agrimensores de Puerto Rico in Arecibo.

February 13, 2015 Public scoping period ended.

1.4 Project Overview 

The proposed facility would process approximately 2,100 tons of municipal waste per day and generate 

a net capacity of 67 megawatts (MW). The Puerto Rico Electric Power Authority (PREPA) would purchase 

power generated from the facility. In addition to municipal solid waste, the proposed facility would be 

designed to combust up to 286 tons per day of auto-shredded residue (ASR), 330 tons per day of tire-
Arecibo Waste-to-Energy Project Scoping Summary Report

derived fuel (TDF), or 898 tons per day of processed urban wood waste (PUWW) as supplementary fuel.

The proposed facility would also recover and recycle 240 tons per day of ferrous metals (such as iron 

and steel, among others) and nonferrous metals (aluminum, copper, and tin, among others).

The proposed project would also include a system for processing bottom ash. This system is designed to 

recover ferrous and non-ferrous metals and would produce a granular material known as Boiler 

AggregateTM. Boiler Aggregate can be used as filler for roadway asphalt and in the manufacturing of 

concrete blocks, among other applications. Energy Answers also proposes to process the fly ash using a 

separate and independent system to condition it for disposal in a landfill or reuse as a marketable 

material.

The facility would be located at the former site of the Global Fibers Paper Mill, and it would cover 

approximately 79.6 acres of the 90-acre parcel. The proposal would include the following facility 

components: a municipal solid waste receiving and processing building; processed refuse fuel storage 

building; boiler and steam turbine; emission control system; ash processing and storage building; and 

other associated infrastructure and buildings. Two other connected actions, which would be constructed 

by Energy Answers, include an approximately 2.0-mile underground raw water line and a 38-kilovolt (kV) 

transmission line approximately 0.8 mile in length.

The proposed project would consist of two spreader-stoker boilers, each with a design heat input rate of 

500 MMBtu/hr, which translates to an approximate waste feed rate of 1,053 tons per day per boiler. 

Each boiler would have three auxiliary oil burners to be used to control system temperatures during 

startup, shutdown, and upset conditions. The boilers would produce steam that would be used to 

generate electricity using a turbine generator. The proposed project would be capable of extracting 

some steam for sale at up to 600 pounds per square inch gauge, or condensing all of the steam for reuse 

using a four cell cooling tower. Electricity would be produced for in-facility usage and for sale to PREPA.

An overhead electric transmission line would connect to the preferred electrical interconnection point 

at the Cambalache Transmission Center (CTC), located at approximately 0.5 mile south of the site. The 

transmission line and the interconnection point in the CTC would have a voltage of 38 kV. The aerial 

power line would run on steel poles 70 feet high and spaced approximately 150 feet apart.

Combustion gases from each boiler would be treated to meet emission regulations using an air quality

control system (AQCS) consisting of an activated carbon injection system, a dry lime injection system, a 

circulating dry fluid bed scrubber, a fabric filter baghouse, and a regenerative selective catalytic 

reduction (RSCR) system for nitrogen oxides (NOx) control. Potable water would be supplied for 

personnel use and consumption. Cooling tower and boiler makeup water would be obtained from the 

existing Department of Natural and Environmental Resources (DNER) discharge from Caño Tiburones to 

the Atlantic Ocean, through an underground force main from the Vigía Pumping Station to the proposed 

facility.

2.0 SCOPING COMMENTS 

An overview of the public concerns expressed during the public scoping meeting is presented in Section 

1.2, Public Outreach, and a summary of comments received during the 2014 and 2015 public scoping 

periods, catalogued by general topic, is provided in Table 2. Issues potentially relevant to the scope of 

the RUS EIS will be considered by RUS during development of the DEIS.

As noted in Section 1.2 and Table 2, many commenters expressed that the public was unaccustomed to 

the format of the scoping meeting and requested additional public scoping meetings and extension of

the scoping period. After reviewing and considering the comments received during the entire scoping 

process, RUS determined that the public has been afforded several avenues to provide comments and 

input into the scoping process and that RUS has received substantive comments that will inform the 

DEIS preparation. RUS will provide the public timely updates on the process and ensure that there is 
Arecibo Waste-to-Energy Project Scoping Summary Report

adequate time for the DEIS review. RUS will also hold public hearings in Puerto Rico for the DEIS. 

Therefore, RUS does not intend to extend the scoping period and hold additional scoping meetings.

Table 2 Summary of Scoping Comments Received by RUS 

Subject Area Comment Summary

NEPA Process (EIS scope, public 

information process, need for 

project)

Purpose and Need

• Commenters objected to the classification of the project as a 

renewable energy activity because they stated that it should be 

clearly defined as a municipal waste incinerator or with the more 

refined term of a WTE system.

• Commenters questioned the purpose of and need for the project, 

noting that the RUS EIS must establish the evidence that the 

demand for solid waste disposal exists (or would exist) for the 

proposed project.

• Commenters questioned the need for the project, stating that

there is an excess of installed energy capacity in Puerto Rico and,

with declining population, less may be required in the future. 

Commenters also stated that the project would produce energy 

that is less than 1% of the energy produced on the island.

• Commenters questioned the viability and need for the 

incineration facility and stated that the PRIDCO EIS used outdated 

population estimates from 2006, that there are one million fewer

people than the projection included in the document, and that 

the reduced population translates to one million tons less of 

waste.

• Commenters stated the need for new comments from local and 

federal agencies regarding project need and impact as a major 

solid waste management project and a minor energy generation 

project.

• Commenters stated that the need identified in the previous EIS as 

it relates to the 2010 Executive Order declaring an energy 

emergency no longer exists, nor is an energy emergency 

identified in Executive Order 2013-038.

Public Involvement 

• Prior to the extension of the scoping period and the public 

meeting, commenters requested public meeting(s) in Puerto Rico;

that the scoping meeting notice and the EIS must be in Spanish to

allow for a more transparent permitting and review process; and 

that public outreach and participation must be expanded.

• Commenters noted that the format of the scoping meeting was 

confusing and not conducive to people providing comments 

because they were used to the format of public hearings. 

Commenters also stated that a description of the proposed project 

was not available at the scoping meeting.

• Commenters requested additional public scoping meetings and 
Arecibo Waste-to-Energy Project Scoping Summary Report

Subject Area Comment Summary

extension of the scoping period.

• Commenters requested additional public scoping meeting(s) 

during off-working hours to facilitate public participation.

• Commenters asked that RUS provide proof of the public 

announcements in local media.

• A commenter stated that RUS should solicit expertise from other 

agencies. 

• Commenters requested an additional scoping meeting without the 

applicant being present.

• Commenters stated that the RUS point of contact had not been 

functioning because the public had not received responses to their 

emails or voicemails and because the RUS website changed and 

did not function for a few days.

Process

• Commenters expressed objection to RUS’ plan to incorporate by 

reference the PRIDCO EIS.

• Commenters questioned why RUS is the lead federal agency for 

the EIS and why USEPA, USACE, or FEMA did not also require an 

EIS.

Permits

• Commenters expressed that the Prevention of Significant 

Deterioration (PSD) permit issued by the USEPA was not 

protective of the health of the community and would not provide 

emissions sufficient controls.

Proposed Project and Alternatives

Alternative to Waste-to-Energy

• Commenters stated that other alternatives with less 

environmental and health impacts such as waste management 

alternatives (reducing, reusing, and recycling) and energy 

generation alternatives (such as solar and wind) must be analyzed.

• Commenters stated that it was important for the EIS to analyze 

the recent demonstration of the viability of profitable recycling 

alternatives for the island's solid waste problem. Municipalities 

such as Carolina and Guaynabo export recycled materials from 

solid waste, make a profit, and provide jobs to people.

• Commenters stated the need to evaluate the project in the 

context of current local policy regarding waste management and 

the hierarchy established in Article 3 of Law No. 70 of September 

18, 1992, as well as subsequent policy statements from the Puerto 

Rican executive and legislative branches.

• Commenters stated the need to reassess the impact on 

municipalities that would not be able to implement effective 

reduction and recycling programs because of possible fines and 

penalties to be imposed through the Solid Waste Authority, as 
Arecibo Waste-to-Energy Project Scoping Summary Report

9

Subject Area Comment Summary

specified in the Waste Delivery and Support Agreement.

Alternate Waste Processing Technologies

• Commenters stated that, although the proposed project is 

primarily a solid waste management strategy, the PRIDCO EIS 

does not evaluate well-known and available alternatives, such as 

solid waste reduction, reuse, and recycling.

• Commenters stated that the alternatives analysis in the EIS should 

examine how the infrastructure choice to handle solid wastes 

would compare to other infrastructure alternatives that would 

favor lower carbon impacts and those alternatives should include 

recycling.

• Commenters discussed that, if the proposed project commits 

Puerto Rico to a particular solution for its solid waste disposal and 

closes out many local recycling, reuse, and reduction of waste 

initiatives, the EIS should present a more comprehensive analysis 

of alternatives.

Alternatives to Water Supply

• Commenters noted that no alternative to water supply was 

evaluated as part of the PRIDCO EIS, and the document needs to 

be revised and updated to include the analysis.

Disposal of Ash

• Commenters requested including the existing ash disposal 

requirements in Arecibo in impact assessment, including ash 

disposals from Safetech Corporation Carolina and the Battery 

Recycling Company Inc.

• Commenters stated that there is a need to conduct an ash 

characterization, disposal, and fate and transport study to define 

health and environmental risks and to define and make public an 

ash management and disposal strategy.

• Commenters recommended conducting a chemical analysis of the 

ashes under an accredited laboratory to ensure the reliability of 

the results and their impacts on public health.

Solid Waste

• Commenters stated that the implementation of the proposed 

project, when acceptable recycling rates have not yet been 

attained and no reduction, reuse, or recycling plans are in place, 

would jeopardize the effective implementation of reducing, 

reusing, and recycling efforts. 

• The commenters stated that the impact assessment in the 

previous EIS regarding the effect on reduced contamination on 

landfills is highly overstated and lacks precision and quantifiable 

data and that the ash disposal on landfills would have a higher 

concentration of contaminants than regular municipal waste 

stream on a per volume basis. The commenters also noted that,

because the information regarding the handling of this residual 

ash was not discussed as part of the PRIDCO EIS, the conclusion in 
Arecibo Waste-to-Energy Project Scoping Summary Report

10

Subject Area Comment Summary

the PRIDCO EIS regarding decreased impact on landfills is false 

and misleading.

• Commenters asked whether solid waste would be imported from 

off of the island because the 2,100 tons required by the proposed 

project would not be generated on the island.

Soils and Geology

Contamination

• Commenters noted that using ash deposit as fill would 

contaminate the soils.

• Commenters noted that the proposed project would contaminate 

the agricultural area surrounding the proposed facility with 

dioxins and heavy metals.

Water Resources

Impacts to Floodplains

• Commenters expressed concern over the potential flooding 

impacts from constructing the plant in the floodplain of the Rio 

Grande de Arecibo River and potential for contamination.

• Commenters stated that locating an incineration facility within 

the floodzone of one of Puerto Rico’s main rivers should be 

questioned particularly when the PR DNER has identified the area 

as the ecologically rich last miles of the Arecibo River.

• Commenters stated that the location of the proposed ash landfill 

should be made known to the residents and whether or not the 

site has ever been affected by flooding.

• Commenters stated the need to assess the impacts of channeling 

of the Rio Grande de Arecibo by the U.S. Army Corp of Engineers, 

specifically impacts on the river’s water levels, speed, and 

concentration at any given moment, but particularly on major 

events such as hurricanes because it is within FEMA’s flood zone.

• Commenters noted that, according to FEMA, the location of the 

proposed project is under a "no-use" area because of floods.

• Commenters noted that the selection of the recycling of sanitary 

waters was done without an analysis of the ecological effects of 

reducing freshwater input into coastal wetlands and coastal 

waters while increasing marine influence on the coastal zone.

Commenters also stated that assurances are needed to the effect 

that the water withdrawal can be sustained without irreversible 

change in salinity or functioning of coastal wetlands.

Impacts to Ecosystems and Potable Water

• Commenters noted that no hydrology and hydraulics (H/H) study 

was presented in the PRIDCO EIS to evaluate the impact of water 

extraction from the Caño Tiburones Reserve. Commenters noted 

that any proposed additional extraction from the Caño Tiburones 

requires a new H/H water study to evaluate the accumulated 

impact of the Dos Bocas extraction during the past decade, as 

well as the impact of future extractions that may be required 
Arecibo Waste-to-Energy Project Scoping Summary Report

Subject Area Comment Summary

from the Superaqueduct system.

• Commenters also noted that, in February 2014, the PR DNER

denied the applicant’s request to extract water from Caño 

Tiburones because of the environmental impacts such an 

extraction would impose on the natural ecosystem. The 

commenters asked, if the alternative source to Caño Tiburones 

would be under the Autoridad de Acueductos y Alcantarillados 

(Water and Sewer Authority), how would the water shortage to 

5,250 families be mitigated.

• Commenters asked how the changes to the water temperature 

would be avoided with the outflow of the water that cools the 

plant.

• Commenters stated the need to assess the impact on the existing 

water project ordered by USEPA through a settlement in Court 

with the Municipality of Arecibo to mitigate and control water 

discharges and flood control on the Rio Grande de Arecibo in La 

Puntilla Sector located 3 to 5 miles downstream from the 

proposed project.

Air Quality

Impacts on Human Health

• Commenters stated that the USEPA PSD permit is inadequate and 

that it allows burning of toxic wastes. They stated that EPA did 

not adequately address the emissions of lead from the facility and 

pointed to a high incidence of childhood lead poisoning in the 

surrounding community.

• Commenters also noted that, since 2011, USEPA declared an area 

of 4 kilometers around the lead smelter facility a nonattainment 

area for lead.

• Commenters noted that the air emissions from garbage trucks 

transporting waste from one corner of the island to get to the 

Arecibo site were not accounted for in the PRIDCO EIS.

• Commenters noted that there were inadequate emission controls 

on the stacks.

• Commenters questioned the indirect impact of use of limestone 

(impacts from quarrying) on air quality.

• Commenters cited problems from incinerators in other countries 

and used Syracuse, New York, ash dispersion problem as an 

example.

Impact Assessment Methodology

• Commenters stated that the explanation of emissions during 

periods of shutdown and startup is extremely limited in the 

PRIDCO EIS and needs to be studied and explained in detail.

• Commenters noted that the EIS should include a health risk 

assessment including impact of nanoparticles.
Arecibo Waste-to-Energy Project Scoping Summary Report

12

Subject Area Comment Summary

• Also see comments under Public Health and Safety.

Acoustic Environment

Facility and Traffic Noise

• Commenters stated that the previous EIS disregards the noise 

impact that would be caused by the operation of the facility, 

particularly the dramatic increase in garbage trucks in the area 

that will transit through PR-2.

• Commenters stated the need to conduct a new noise level study 

that accounts for predictable noise polluting activities that would

be expected and the impact on quiet zones and residential areas.

Biological Resources

Protected/Special Species

• Commenters stated that the EIS must analyze the impacts from 

the ashes and other chemicals on the Puerto Rican parrot, an 

endangered species.

Protected Lands/Reserves

• Commenters stated that the EIS must analyze the impact of the 

quality of water discharge on the river and its ecosystems, 

especially on the Ceti in Arecibo’s Rio Abajo Natural Reserve 

forest.

Land Resources

• Commenters noted that the project is within 1 mile of an airport.

• Commenters noted that the project location is not in a rural area, 

but a residential area with educational institutions that may be 

affected by the project.

• Commenters noted that, in the area of the proposed project, 

there is productive land used for agriculture.

Visual Resources

• Commenters noted that there are no renditions of the visual 

impact of the project on the region and particularly from 

reference points outside property boundaries.

• Commenters stated that there would be visual impacts from the 

waste collection centers and that the project would bring more 

waste to the surrounding areas.

Transportation 

• Commenters stated that the transport of the ash represents an 

additional impact.

• Also see comments under Noise and Air Quality.

Cultural Resources/Historic 

Properties

• Commenters noted that the areas of potential effects of the 

project extend beyond the archaeological surveyed areas 

included in the PRIDCO EIS and that the documentation is 

insufficient to evaluate the potential effects on historic 

properties. A commenter also noted that no studies have been 

conducted in the areas where the pipelines that are to bring 

water to the plant from Caño Tiburones would be installed and 

that the segment along PR 681 crosses areas that are 

archaeologically sensitive.

• Commenters requested to become consulting parties to the 

Section 106 process.

Public Health and Safety

• Commenters noted that Arecibo and Hatillo, adjacent cities have 

among the highest prevalence of asthma (~16%) and very high 

mortality, both well above the national averages.

• Commenters noted that the fact that Arecibo is a non-attainment 

area should also constitute an important element of the 

environmental justice evaluation in the EIS.

• Commenters expressed concerns that the project would increase 

air pollution in a community that has already suffered for more 

than 10 years from the impact of contaminating industries and 

stated the need for a cumulative analysis of the contamination.

• Commenters noted that Human Health Risk Assessment (HHRA) 

referenced in the PRIDCO EIS document must be revised because 

it is based on incomplete information. The commenter expanded 

that the need for a revised HHRA is because it must be based on 

an updated waste characterization study for Puerto Rico and not 

the SEMASS facility in Massachusetts, include a cumulative impact 

analysis, and incorporate local studies made by Colegio de 

Médicos de Puerto Rico and the Centers for Disease Control. 

• Commenters stated that the EIS should include a health risk 

assessment including heavy metals such as mercury.

• Commenters stated that risk assessment procedures established 

by the World Health Organization should be used.

• Commenters stated that the project represents a threat not only 

to human health but also to agriculture because the smoke stack 

of an incinerator disperses pollutants such as dioxin, which affects 

agriculture and cattle and concentrates in animal fat. 

Commenters noted that more than 25,000 people depend on the 

areas of Arecibo, Hatillo, and Camuy, which is Puerto Rico’s “Dairy 

Belt,” for their living.

• Commenters noted that the entire food chain would be 

contaminated.

• Commenters stated that the EIS must specify the health risks to 

the workers at the WTE plant.

• A commenter asked how the applicant would manage a fire. 

Another commenter noted the need for contingency plan in case 

of a fire because SEMASS had a fire that lasted for 3 days that 

required several fire departments and the neighbors were 

confined to their houses for days because of the toxic emissions.

Socioeconomics and 

Environmental Justice

• Commenters questioned the projection of jobs in the PRIDCO EIS 

and stated that, compared to similar facilities in the United 

States, the number seemed to be overstated. Commenters stated 

that a more in-depth analysis of job creation from the project is

needed.

• Commenters stated that the PRIDCO EIS used outdated 

population estimates from 2006. They stated that there are one 

million fewer people than the projection included in the 

document and that the reduced population translates to one 

million tons less of waste.

• Commenters stated that a large proportion of the money invested 

would not benefit the economy of Puerto Rico because it would

go to the purchase of technology off-island.

• Commenters stated the need to conduct an in depth and 

thorough environmental justice study as required by NEPA and 

Council on Environmental Quality regulations, specifically taking 

into account the persistent siting of contaminating and polluting 

industries and activities in the Arecibo Region within economically 

depressed communities.

• Commenters stated that the proposed project violates the 

principles of environmental justice because incinerators are 

disproportionately sited in poor or rural communities and areas of 

least political power.

• Commenters noted that the proposed project would impact ecotourism in places such as the Cuenca de Caño Tiburones, Bosque 

Cambalache, and Playa Posa as well as universities, schools, and 

day care facilities.

• Commenters noted that the proposed project would not benefit 

the economy in the area.

Climate Change

• Commenters stated that the proposed project’s contribution to 

global climate change must be evaluated because incinerators 

emit significant quantities of direct greenhouse gases (GHGs), 

including carbon dioxide and nitrous oxide, that contribute to 

global climate change and because their greatest contribution to

climate change is through undermining waste prevention and 

recycling programs, and encouraging increased resource 

extraction.

• Commenters stated the need to assess the emissions of GHGs that 

would be associated with the proposed project during its lifetime. 

This includes both direct and indirect emissions attributable to the 

construction and operation of the incinerator (including the 

transportation of solid wastes and ash wastes to and from to the 

facility)

• A commenter noted that the RUS EIS must discuss the impacts of 

the proposed project on broader foreign policy objectives, 

including a comprehensive strategy to address climate change.

• Commenters stated the need to assess the emissions of GHGs and 

their interrelationship with dust from the Sahara Desert, which 

has been flown in by air currents over the entire island of Puerto

Rico on an increasing regular basis.

Energy Use and Sustainability

• Commenters stated that WTE wastes energy, recovering energy 

by burning costs more energy, and the use of raw material (if 

available) to replace burnt products would require even more 

energy.

Cumulative Impacts

• Commenters expressed concerns that the project would increase 

air pollution in a community with existing polluters, including a 

lead smelter facility that is located approximately 2,000 feet from 

the project location. Commenters stated the need for a 

cumulative analysis of the contamination. 

• Commenters stated that a comprehensive cumulative impact 

analysis that considers impacts on ecologically sensitive and 

environmentally rich areas of the Arecibo Region is needed. 

Project Finances and Use of 

Public Funds

• Commenters questioned the use of the public funds for the 

project because there is an excess of installed energy capacity in 

Puerto Rico and with declining population may require less in the 

future. Commenters also stated that the project would produce 

energy that is less than 1% of the energy production on the island.

• Commenters questioned whether the location of the project, 

Arecibo, meets the criteria of rural as defined under 7 USC 1926 

(D) (13).

• Commenters stated that Title 7 U.S.C. 1926 funds would not be 

available when the proposed project violates compliance with the 

Safe Drinking Water Act.

• A commenter noted that 7 CFR, Subtitle B, Chapter XVII, Subpart 

D, Section 1700, establishes that, if funds are already invested 

producing energy, RUS is required to determine whether a debt 

exists for such technology. From there, RUS is required to 

evaluate whether the applicant has a private interest that 

endangers public use.

• Commenters requested that RUS make public the entire 

information regarding the financial aid solicited by the applicant.

• A commenter noted that, if RUS is interested in subsidizing a 

project that truly supports agriculture, it should withhold loans

from the applicant and provide assistance for clean water in 

Arecibo.

• Commenters stated that overall costs of the project must be 

reassessed in the light of lower oil prices and the benefits of a 

municipal waste incineration facility in lieu of other alternatives 

with less environmental and health impacts such as waste 

management alternatives (reducing, reusing, and recycling) and 

energy generation alternatives such as solar and wind.

• Commenters asked who would have the financial liabilities if the 

project goes bankrupt.

Subject Area Comment Summary

PRIDCO EIS

• Commenters stated that the public review period for the PRIDCO 

EIS was inadequate.

• Commenters stated that the PRIDCO EIS document must be 

revised because it is based on incomplete and outdated 

information.

Additional Studies

• Commenters stated that, because the applicant proposes to 

change the topography of the area and would impact public 

wetlands for private economic benefit, the public deserves a 

cost/benefit analysis for such a tradeoff.

• Commenters noted that, at a minimum, a new waste 

characterization study should be completed to better assess the 

type of pollutants and amounts that can be expected to be 

released, thus allowing for a better assessment of the 

environmental and health impacts. Commenters also noted that 

the study would provide the specific volumes of recyclables and 

toxic materials that would enter the incineration waste stream 

and also determine the project’s viability.

• Commenters also noted that no studies have been conducted in 

the areas where the pipelines that are to bring water to the plant 

from Caño Tiburones are to be installed and that the segment 

along PR 681 would cross areas that are archaeologically 

sensitive.

• Commenters suggested that RUS require the applicant to use the 

most advanced scientific model, known as the leaching 

environmental assessment framework, to consider the impacts of 

the ash disposal.

• Commenters requested a new noise level study that accounts for 

noise polluting activities that could be expected and the impact 

on quiet zones and residential areas.

• Commenters noted that no H/H study was presented in the 

previous EIS document to evaluate the impact of water extraction 

from the Caño Tiburones Reserve.
