A Política Nacional do Meio Ambiente visa compatibilizar o desenvolvimento socioeconômico com a qualidade ambiental. A Avaliação de Impacto Ambiental, um de seus instrumentos, utiliza-se do Estudo de Impacto Ambiental (EIA) na sua aplicação em projetos ou empreendimentos. A elaboração do EIA envolve a etapa de diagnóstico para análise da qualidade ambiental da área. A qualidade do EIA e do diagnóstico tem sido objeto de críticas e descrédito junto à sociedade, principalmente à comunidade científica e às associações ambientalistas. Sabe-se que a qualidade do diagnóstico influencia diretamente a efetividade processual do EIA e seu papel como influenciador da tomada de decisão; assim, uma avaliação da qualidade dessa etapa do EIA contribui com a aplicação mais efetiva desse instrumento. A pesquisa visou avaliar a qualidade do diagnóstico biótico dos EIAs do Estado de São Paulo elaborados entre 2005 e 2014. Para isso, proposições ao diagnóstico biótico foram reunidas em uma lista de verificação, utilizada para a avaliação de 55 diagnósticos bióticos e 35 termos de referência de EIAs. Os resultados foram analisados qualitativamente e em comparação com as recomendações dos termos de referência (TRs) analisados. Posteriormente, a qualidade dos diagnósticos foi analisada sob três perspectivas: aprovação dos estudos, tipo de empreendimento e ano de elaboração do EIA. Por fim, foi realizada análise de componentes principais não-linear (NLPCA) para os dados de diagnóstico, no intuito de testar a sugestão de aplicação dessa ferramenta para a identificação dos critérios determinantes para a qualidade dos diagnósticos e possíveis relações entre esses critérios e entre os estudos. A qualidade dos diagnósticos bióticos analisados foi mais satisfatória para aspectos descritivos do que analíticos. Foram determinantes para a qualidade dos estudos critérios relativos à coleta de dados quantitativos e levantamentos para espécies raras, segundo a NLPCA. Tempo de levantamento e sazonalidade foram considerados insatisfatórios, e apresentaram relação estatística com a identificação do grau de vulnerabilidade da área. Os resultados realçaram a importância da sistematização de dados de biodiversidade em fontes confiáveis e atualizadas para elaboração e análise de diagnósticos, e para TRs mais específicos, uma vez que, apesar de estarem sendo cumpridos pelos estudos, os TRs são genéricos e apresentam mais recomendações descritivas do que analíticas. Não houve diferença representativa entre a qualidade dos diagnósticos referentes a estudos aprovados e não aprovados, o setor de Obras Hidráulicas apresentou avaliações mais satisfatórias, o que foi salientado pela NLPCA e pode estar relacionado ao porte do projeto, e a análise temporal evidenciou uma tendência de melhora dos estudos e TRs. Tanto a lista de verificação quanto a NLPCA se mostraram ferramentas adequadas para a investigação da qualidade de diagnósticos biológicos de EIA / The Brazilian National Environmental Policy established Environmental Impact Assessment (EIA) as one of the 13 tools to reconcile socio-economic development with environmental quality. EIA involves the Environmental Impact Statements (EIS) in its application to development projects. EIS drafting involves a baseline step for analysis of environmental quality of the area. The quality of the EIS and the baseline process has been criticized by society, especially by scientific community and environmental groups, and this quality directly influences the effectiveness of the EIA procedure and its role as a decision making tool. Thus, an evaluation of the quality of this EIS step contributes to a more effective application of this instrument. The research aimed to evaluate the quality of biotic baseline studies of EIS drawn up between 2005 and 2014 in the state of São Paulo. We assessed 55 biotic baseline studies and 35 terms of reference (TRs) of EISs by a checklist which consists of a set of recommendations from literature and regulations to biotic baseline studies. The results of baseline and TRs were analyzed qualitatively and compared to one another. Then, we looked at the baseline quality under three approaches: license emission, sector and project type of activity, and year of EIS preparation. Finally, multivariate analysis was performed by Nonlinear Principal Component Analysis (NLPCA) for the baseline quality data in order to test the application of this analysis for the identification of critical and determinant criteria for the quality of baseline and the investigation of how these criteria and the EISs are related to one another. Results point to more satisfactory descriptive than analytical issues. Criteria of quantitative data collecting and surveys of rare species were determinants for baseline quality. Time of survey and seasonality was an unsatisfactory criterion, and statistically related to the vulnerability degree of the area. Results highlighted the importance of systematization of biodiversity data in reliable and updated sources useful for EISs preparation and analysis and for the draft of TRs in a more specific way. TRs were satisfactorily complied by the baseline content, but they are generic and present more descriptive than analytical recommendations. There was no representative difference between the quality of baseline of approved and not approved EISs. Hydraulic project showed more satisfactory evaluations, emphasized by NLPCA, and it may be related to the size of the project. Temporal analysis highlighted an improvement trend of studies and TRs. Thus, both the checklist as NLPCA proved to be suitable tools to the assessment of biological baseline studies of EIS

O aumento da inundação em áreas do baixo curso do rio Taquari, no Pantanal do estado do Mato Grosso do Sul, tem transformado a pecuária desta região numa atividade com baixa rentabilidade, à medida que extensas áreas de campo passaram a ser inundadas vários meses durante o ano a partir da década de 70. A pecuária realizada em campos naturais de regiões úmidas do Pantanal indica que há necessidade de se investigar metodologias apropriadas para avaliação de impacto ambiental, que abordem impactos diretos, indiretos, cumulativos e processos do meio físico que alteram, de maneira prejudicial, o meio ambiente. Supõe-se que a inundação na planície do rio Taquari esteja relacionada com a ocupação antrópica nas áreas de planalto da bacia do rio Taquari. O presente trabalho tem por objetivo avaliar os impactos ambientais na planície de inundação do baixo curso do Taquari, decorrentes da ocupação antrópica da bacia hidrográfica do rio Taquari em sua totalidade, considerando os impactos ambientais causados pela pecuária à medida que se configura como principal atividade econômica da bacia bem como os processos erosivos e de assoreamento no quadro atual do regime de inundações. As etapas de caracterização da área, de análise dos impactos e as propostas de ações mitigadoras, previstas num Estudo de Impacto Ambiental, foram aqui analisadas. Foram utilizadas informações sobre as características do meio físico, biótico e socioeconômico, selecionadas a partir do levantamento dos dados existentes com recorte efetuado para a bacia hidrográfica do rio Taquari. Na maior parte dos temas, este foi um processo de levantamento, ordenamento e recuperação de informações, na escala original de 1:250.000, do Plano de Conservação da Bacia do Alto Paraguai-PCBAP, gerenciado no SPRING. Foram também realizadas viagens de campo para a complementação dos dados e para o levantamento de atividades antrópicas com verificações \"in loco\" da ocorrência de impacto ambiental. A maioria dos dados socioeconômicos compilados para o presente trabalho teve por base os censos agropecuários e demográficos realizados pelo IBGE. Os resultados obtidos demonstram que os impactos ambientais decorrentes da pecuária no planalto interferem no regime de inundação na planície da bacia, o que só foi possível de ser identificado a partir de análises integradas em toda a bacia hidrográfica do rio Taquari. Verificou-se que os métodos de EIA são adequados para identificar os impactos diretos decorrentes da pecuária, mas não são adequados para identificar os processos e seus efeitos cumulativos na extensão da bacia hidrográfica do rio Taquari. Além disto, a abordagem da avaliação ambiental estratégica, como procedimento para análise ambiental em políticas, planos e programas, mostra-se adequada para as análises na BHRT à medida que está centralizada nos efeitos do ambiente sobre as necessidades e oportunidades de desenvolvimento. Contudo, somente a recuperação de danos ambientais, o controle das origens dos impactos no ambiente e um sistema de gestão consciente de seus compromissos podem levar, juntamente com a melhora dos procedimentos técnicos e administrativos para análises ambientais, à uma maior proximidade da sustentabilidade ambiental na BHRT. / The increase of flooding in the low course areas of Taquari river in the Pantanal - Mato Grosso do Sul state, has been transforming the cattle raising activity to a low profit activity in the region, when that extensive areas of pasture started to be flooded throughout several months a year from the 1970s. Since these areas are located in the Pantanal region where cattle raising activity is carried on in natural pasture it is necessary to investigate suitable methodologies for evaluation of the ambiental impact, approaching direct, indirect and cummulative impact as well as the processes that change, in a harmful way the environment. The flooding in the floodplain in Taquari river is supposed to be related to the anthropic ocupation in the upland areas of the Taquari river watershed. This work aims to evaluate the environmental impact caused by the anthropic ocupation, the cattle raising activity in the basin and the erosion and silting process in the flood plain of the Taquari river low course. The steps for the area characterization, the analysis of the impact and proposals viewing to diminish the problem, projected in an EIA (Environmental Impact Study), were also considered here. Information on the physical, biologic and socio-economic environment, selected from pre existent data survey, carried on for the Taquari river watershed (BHRT) were used here. For most of the themes, this was a process of surveying and recovering information in the original scale of 1:250.000 from the PCBAP managed in the SPRING GIS model. Field work to complement the existent data to survey the environmental impact of anthropic activities were also carried on. Most of socio-economic data used here were based on the cattle raising activity and demographic census data from IBGE. The results show that the environmental impact caused by cattle raising in the upland interferes in the flooding system in the watershed flood plain, and this fact could only be identified from the integrated analysis of the whole Taquari river watershed. It was observed that the EIA methods are suitable to identify the direct impact caused by the cattle raising activity, but they are not suitable to identify the process and its cummulative effects along the Taquari river watershed. Moreover, it was observed that the approach of the Strategic Environmental Assessment (SEA) as a procedure for environmental analysis in the policies, plans and programs is suitable for the analysis in the BHRT when it is centralized in the effects of environment on the necessities and opportunities of development. However, only the recovering of ambiental damage, the control of the effects caused by impacts on the environment and a system of conscient management can lead to an improvement in the technic and administrative procedures for a really possible ambiental sustentability in the BHRT.

A study was undertaken to determine if light-weighting orbital launch vehicles (rockets) improves lifetime environmental impacts of the vehicle. Light-weighting is performed by a material substitution where metal structures in the rocket are replaced with carbon fiber reinforced polymers (CFRP’s). It is uncertain whether light-weighting the rocket in the same way as traditional vehicles are light-weighted would provide similar environmental benefits. Furthermore, the rocket system is significantly different from traditional vehicles and undergoes an atypical lifecycle, making analysis non-trivial. Seventy rocket configurations were sized using a Parametric Rocket Sizing Model (PRSM) which was developed for this research. Four different propellant options, three staging options, and eighteen different lift capacities were considered. Each of these seventy rockets did not include CFRP’s, thus establishing a baseline. The seventy rockets were then light-weighted with CFRP’s, making a total of seventy pairs of rockets. An environmental Life Cycle Assessment (LCA) was performed on each of the rockets to determine lifetime environmental impacts. During the Life Cycle Inventory (LCI), a Carbon Fiber Production Model was developed to determine the environmental burdens of carbon fiber production and to address issues identified with carbon fiber’s embodied burdens. The results of the LCA were compared across all rockets to determine what effects light-weighting had on environmental impact. The final conclusion is that light-weighting reduces lifetime environmental impacts of Liquid Oxygen-Rocket Propellant 1 and Nitrogen Tetroxide-Unsymmetrical Dimethylhydrazine rockets, while it likely benefits Liquid Oxygen-Liquid Hydrogen rockets. Light-weighting increases lifetime environmental impacts of Solid Propellant rockets.

Across the globe, both developed and developing countries strive to continuously increase economic growth. Many strategies have been developed to guide these countries towards achieving growth and development in a sustainable manner. For many of these countries, cites have become the hubs with regards to the various socio-economic activities taking place within countries. This has in turn subjected cities to tremendous growth. The increased growth of cities has been characterized by radial expansion, wherein development spreads out from the city center to the fringes. The radial expansion of cities has not always been under control or properly managed by government or the private sector as well as the relevant role playing stakeholders. Many socio-economic and environmental challenges have been associated with the rapid urban development that spreads into urban fringes. This dissertation focuses on assessing the sustainability of urban fringes and their developments. It presents a conceptual framework that tackles multiple urban fringe challenges and their various causes as well as the possible solutions thereof. It also focuses on empirically assessing the sustainability of the Cato Ridge urban fringe development in eThekwini Municipality, KwaZulu-Natal Province. The study discovers that the challenges of urban fringe development are economic, social and environmental. It concludes with recommendations for addressing policies of urban fringe developments in order to ensure sustainability. / M.T.R.P. University of KwaZulu-Natal, Durban 2013.

The increase in global population and high urbanisation rates characterised by high resource consumption and waste generation levels has led to challenges in waste management around the world. Waste management remains one of the most critical challenges faced by local governments in developing countries. Informal business enterprises have come under the spotlight for their high waste production and poor waste management practices. Many arguments have been put forward as to the real environmental impacts caused by informal business enterprises due to their waste practices. This research aimed at assessing the waste management practices in the informal business sector in Olievenhoutbosch Township, Pretoria. Data collection was carried out between March 2016 and September 2016. The research utilised both qualitative and quantitative methods. The methodology employed techniques that included structured questionnaires, structured interviews and field observations. Semi- structured face to face interviews were carried out with key informants. These interviews provided information on the frequency of waste collection, available waste management awareness and challenges faced in delivering the service. The research also involved 230 field observations to study the pattern and frequency of waste collection and waste behaviours by informal business enterprises. Questionnaires were administered to 120 informal business enterprises with a response rate of 84.17%. Data from questionnaires and field observations indicated that waste generated by informal business enterprises (plastic bags, card board, packaging plastics, glass bottles and plastic bottles) was mainly recyclable waste. The most preferred disposal methods were use of refuse plastic bags (31%), open space dumping (20%) and burning (30%). Analysis of the results showed that there was lack of information on waste management and that also influenced waste behaviours. Preferences for waste disposal methods were influenced by many factors including lack of information, shortage of waste disposal facilities and waste collection frequency by the local town council. The research found that waste collection in various sections of the township was done once per week which has led to increased indiscriminate waste dumping and burning of waste. It was recommended that waste management information be provided to informal business enterprises especially on waste separation and recycling. The municipality should increase frequency of waste collection or provide central point waste facilities to business operators. / Environmental Sciences / M. Sc. (Environmental Science)

O etanol de cana-de-açúcar tem se destacado no cenário mundial como uma potencial fonte de energia alternativa aos combustíveis fósseis. Entretanto, sua produção é fortemente baseada na monocultura, intensificando os impactos adversos nos recursos ambientais. Esses impactos podem se combinar e persistir ao longo do tempo, possibilitando o acúmulo destes nos recursos ambientais, tornando-se necessário um planejamento mais adequado da produção do bioetanol, para que uma abordagem mais sistêmica seja integrada a esse processo. Em meio a esses fatores, a consideração de impactos cumulativos é um elemento essencial para a sustentabilidade do etanol, por conseguir avaliar de maneira mais holística as implicações da monocultura, sendo obrigatória durante o processo de licenciamento ambiental do setor. Essa prática pode ser viabilizada por meio da AIA, possibilitando que esses impactos possam ser identificados e avaliados para que a viabilidade ambiental dos empreendimentos do setor possa ser atestada, principalmente pela elaboração de um EIA. Apesar da exigência, há indícios de que a prática da inserção destes impactos não tem sido realizada adequadamente. Diante do exposto, a pesquisa teve como objetivo analisar de que maneira os impactos ambientais cumulativos estão sendo inseridos em Estudos de Impacto Ambiental do setor sucroenergético paulista, à luz dos elementos preconizados pela AIC. Para tal, foram caracterizados potenciais impactos ambientais cumulativos provenientes da monocultura de cana-de-açúcar nos componentes ambientais águas superficiais, águas subterrâneas, biota aquática e fauna e flora terrestre; além da definição de critérios para as análises nos estudos ambientais. Assim, verificou-se a prática atual da consideração desses impactos nos EIAs do setor canavieiro. A metodologia foi baseada em pesquisa bibliográfica, entrevistas semiestruturadas, modelo causal e análise documental. Como resultados, constatou-se que os impactos ambientais cumulativos não têm sido considerados adequadamente nos EIAs, tendo como base os critérios adotados na análise. Dentre as fragilidades encontradas, destaca-se a falta da identificação e consideração nas análises de outras atividades do passado, presente e futuro, bem como a definição de limites temporais. Além disso, observou-se que alguns dos impactos cumulativos identificados pela pesquisa são contemplados nos estudos como impactos diretos e indiretos. Considerando que as monoculturas podem ser caracterizadas como fontes de mudanças ambientais sob ampla perspectiva espacial e temporal, e diante de sua natureza repetitiva, há uma necessidade de estabelecimento de requisitos, procedimentos e métodos a serem empregados para avaliação destes impactos. Neste contexto, os Termos de Referência poderiam direcionar essa avaliação por meio da definição de critérios a serem contemplados nos estudos, possibilitando uma compreensão das perturbações das áreas de cultivo em sistemas ambientais e a definição de limites a serem observados, além de agregar valor aos processos de tomada de decisão sobre a viabilidade ambiental de empreendimentos do setor sucroenergético no estado de São Paulo. / Sugarcane ethanol has distinguished itself worldwide as a potential alternative energy source to fossil fuels. However, its production is heavily based on monoculture, intensifying the adverse impacts on environmental resources. These impacts may combine to persist over time, allowing the accumulation of these on environmental resources, making necessary a more appropriate planning of bioethanol production, for a more systemic approach into this process. Amidst these factors, addressing cumulative impacts is an essential element for the ethanol sustainability, able to assess a more holistic manner the implications of monoculture, being required during the environmental licensing process industry. This practice can be conducted through the EIA, enabling these impacts can be identified and assessed for environmental feasibility of projects in the sector can be attested, mainly by establishing an EIS. Despite the demand, there is evidence that the practice of addressing these impacts have not been adequately performed. Given the above, the research aimed to analyze how the cumulative environmental impacts are being entered into the Environmental Impact Statements of São Paulo sugarcane industry in light of the elements recommended by the CIA. To this end, potential cumulative environmental impacts from sugarcane monoculture in the environmental components surface waters, groundwater, aquatic biota and terrestrial fauna and flora were characterized, beyond the definition of criteria for analysis in environmental studies. Thus, we found the current practice of considering these impacts in EIS of sugarcane industry. The methodology was based on a literature review, semi-structured interviews, document analysis and causal model. As a result, it was found that the cumulative environmental impacts have not been adequately considered in EIS, based on the criteria used in the analysis. Among the weaknesses found, there is a lack of identification and the analyze of other activities of the past, present and future, as well as setting time limits. Moreover, it was observed that some of the cumulative impacts identified by the survey are included in the studies as direct and indirect impacts. Whereas monocultures can be characterized as sources of environmental changes on large spatial and temporal perspective, and before their repetitive nature, there is a need to establish requirements, procedures and methods to be employed for the assessment of these impacts. In this context, the Terms of Reference could direct this review by defining the criteria to be included in the studies, enabling an understanding of the disturbances growing areas in environmental systems and setting limits to be observed, besides adding value to decision- making process on the environmental feasibility of the sugarcane industry developments in the state of São Paulo.

No Brasil, a Avaliação de Impacto Ambiental (AIA), devido a exigência legal e por estar vinculada ao sistema de licenciamento ambiental, é o instrumento/procedimento de gestão ambiental mais conhecido. Porém somente após a publicação da Resolução CONAMA 001/86 é que a AIA, por meio da elaboração do EIA/RIMA e sua análise e discussão, passou efetivamente a ser implementada. Apesar de existirem exemplos de aplicação bem sucedida do processo, verifica-se que os resultados esperados não têm sido satisfatórios para o que se pretende com ele. Falhas tanto na elaboração dos EIAs como na condução das demais fases da AIA têm sido verificadas. Empresários vêem o processo de AIA, principalmente a elaboração do EIA/RIMA, como empecilho legal e burocrático. Enfim, têm-se verificado deficiências na condução, na eficácia da AIA e naquilo que se pretende com esse instrumento de política pública, que é a busca da sustentabilidade do desenvolvimento. Alguns o enxergam, inclusive, como um processo falido. Diante desse quadro, o presente trabalho buscou, principalmente com base em documentos disponíveis no órgão ambiental estadual e em informações obtidas junto às empresas, avaliar a eficácia da AIA como instrumento de gerenciamento ambiental junto de empreendimentos minerais localizados no Quadrilátero Ferrífero de Minas Gerais. Os resultados permitem observar, apesar das deficiências verificadas no seu desenvolvimento, que a AIA em função da gestão ambiental foi mais eficaz em alguns casos que em outros, porém em nenhum deles teve desempenho nulo. As principais falhas verificadas estão na análise dos impactos ambientais do projeto, na fragilidade dos levantamentos de dados de base relacionados ao plano de monitoramento e na condução dos planos de monitoramento. Para os empreendedores, a AIA pouco se relaciona com a pretensa certificação ambiental do empreendimento e unanimemente todos consideram, principalmente, a elaboração da AIA como apenas uma exigência para o licenciamento ambiental do empreendimento. / In Brazil, the Environmental Impact Assessment (EIA) is a legal requirement and has being linked to the environmental licensing system. In addition, the EIA has been the most well known tool of environmental management. However, just after the approval of CONAMA Resolution 001/86, the EIA has been implemented through the elaboration of the EIA/RIMA report, its analysis and discussion. Although there are examples of wellsucceed process application, most of the results have been unsatisfactory. This is a consequence of errors both in the EIA\'s design and application.Many entrepreneurs have considered the EIA process, mainly the EIA/RIMA report, as a legal and bureaucratic constraint. Some see it as a tool with a failed process. In fact, a series of deficiencies have compromised the EIA efficiency, the results are expected from its application, and the search for environmental sustainability. Considering the situation described above, the present studies have the objective of evaluating the EIA efficiency as an environmental managing tool in mining companies of the Quadrilátero Ferrífero, Minas Gerais, Brazil. Most of the basic information was obtained from the governmental environmental agency and the mining companies referred to above. The results of this work have allowed to conclude that the EIA, due to different environmental managing effort, has been more efficient in some cases than in others. Nonetheless, no null result was detected. Main deficiencies of the process reside in the analysis of the project environmental impacts, in the fragility of the field data, on the conduction of the monitoring plan, and the way those data are archived. According to the entrepreneurs, the EIA is poorly related to the environmental certification of the project, all of them consider the EIA application just a legal requirement for the project licensing.

Embora recente em termos históricos, a preocupação de indivíduos e governos quanto à capacidade de suporte do meio, face aos efeitos das intervenções antrópicas e da enorme probabilidade de danos irreparáveis para as condições de todas as formas de vida, implicou na necessidade da gestão dos recursos ambientais e do disciplinamento dessas intervenções, buscando-se instrumentos técnicos e jurídicos adequados. A avaliação de impacto ambiental (AIA) e o licenciamento ambiental com eficaz participação da sociedade, são cruciais para abalizar decisões e garantir um mínimo de sustentabilidade ambiental. A inserção do Brasil nesse contexto se dá com a lei nº 6938/81, que estabelece a Política Nacional do Meio Ambiente (PNMA), porém, ganha corpo na Constituição Federal de 1988, com a exigência sine quan non de prévia elaboração e publicidade do Estudo de Impacto Ambiental (EIA) para as hipóteses de degradação ambiental significativa. Nada obstante, a Secretaria do Meio Ambiente do Estado de São Paulo edita a Resolução SMA nº 42/94, permitindo o licenciamento subsidiado apenas em um incógnito Relatório Ambiental Preliminar (RAP), instrumento técnico de elaboração prévia obrigatória, quebrando a aparente harmonia normativa até então vigente. Restou evidenciado neste trabalho que a própria Resolução SMA nº 42/94, assim como o RAP, que não tem seu conteúdo mínimo fixado na regra jurídica que o criou, são objetos de dissensões técnicas e jurídicas que possibilitam o questionamento do procedimento de licenciamento ambiental quanto à sua legitimidade, o que pode levar à anulação da licença ambiental expedida por vício de origem. / Although historically recent, the individual and governmental preoccupation towards the capacity of nature to provide for the human beings, due to their interventions and the enormous probability of irrecoverable damage to the conditions of life for all forms of lives, has engendered the necessity for the orderly management of the natural resources, seeking technical and legalized instruments for the task. The Environmental Impact Statement (EIS), and the environmental licensing, plus the efficient society participation, are crucial to backup decisions and assure a minimum of environmental sustainability. Brazil\'s insertion in this context begins with the Law nº6938/81, which establishes the National Environment Policy (PNMA, in Portuguese), and is enhanced in the Federal Constitution of 1988 by the sine qua non requirement of previous elaboration and publicity of the EIS. Notwithstanding, the rules imposed by the Environmental Office of the Government of São Paulo State (SMA, in Portuguese) Resolution nº 42/94 endorsing the licensing subsidized solely by an incognito Preliminary Environmental Report (RAP, in Portuguese), shattered the seemingly normative harmony existent and became a source for dissensions that make it possible to question the legitimacy of the license issued. It is evinced in this work that the very Resolution SMA nº 42/94, along with the RAP - which has not its minimum contents described by the rule that created it - are subject to technical and juridical dissensions that might give room to the questioning of the environmental licensing as to its legitimacy by a flaw, that might lead to the annulment of the issued license.
