Previous issue date: 2011-01-31 / Today a major responsibility for the contamination of soil and groundwater and surface water
are establishments known as gas stations of fuel which has attracted increasing attention from
both the general population as the state agencies of environmental control due to leaks in
storage tanks and mainly to disruption of pipe corrosion of tanks and pumping. Other
services, like oil changes and car wash are also causes for concern in this type of
establishment. These leaks can cause or waste produced, and the contamination of aquifers,
serious health problems and public safety, since most of these stations located in urban areas.
Based on this, the work was to evaluate soil contamination of a particular service station and
fuel sales in the city of Natal, through the quantification of heavy metals like Cd, Cu, Cr, Ni,
Pb, Zn of total organic carbon (TOC) and organic matter using different techniques such as
optical emission spectrometry with inductively coupled plasma source (ICP OES), Total
Organic Carbon analyzer and gravimetric analysis respectively. And also to characterize the
soil through particle size analysis. Samples were taken in 21 georeferenced points and
collected in the same period. The soils sampled in sampling stations P3, P5, P6, P10, P11,
P12, P13, P14, P15, P17, P18 and P20 showed the smallest size fractions ranging from fine
sand to medium sand. The other study sites ranged from fine sand to medium sand, except the
point P8 showed that only the type size medium sand and P19, indicating a particle size of the
coarse type. The small correlation of organic matter with the elements studied in this work
suggests that these are not of anthropogenic origin but geochemical support / Hoje um dos grandes respons?veis pela contamina??o do solo e ?guas subterr?neas e
superficiais s?o os estabelecimentos conhecidos como postos de revenda de combust?veis que
vem merecendo cada vez mais aten??o tanto da popula??o em geral como dos ?rg?os
estaduais de controle ambiental devido a vazamentos em tanques de armazenamento, e
principalmente ao rompimento da tubula??o de bombeamento e corros?o dos tanques. Outros
servi?os como, troca de ?leo e lavagem de autom?veis tamb?m s?o motivos de preocupa??o
neste tipo de estabelecimento. Estes vazamentos ou residuais produzidos podem causar, al?m
da contamina??o de aq??feros, graves problemas de sa?de e de seguran?a p?blica, visto que a
maioria destes postos localiza-se em ?reas urbanas. Baseado nisto, o trabalho realizado teve
como objetivo avaliar a contamina??o do solo de um determinado posto de servi?os e revenda
de combust?veis na Cidade de Natal, RN, por meio da quantifica??o de metais pesados como
Cd, Cu, Cr, Ni, Pb, Zn, do teor de carbono org?nico total (COT) e da mat?ria org?nica
utilizando t?cnicas distintas como espectrometria de emiss?o ?ptica com fonte de plasma
indutivamente acoplado (ICP OES), analisador de Carbono Org?nico Total e an?lise
gravim?trica respectivamente. E ainda caracterizar o solo por meio de an?lise granulom?trica.
As amostragens foram realizadas em 21 pontos georeferenciados e coletadas no mesmo
per?odo. Os solos amostrados nas esta??es de coleta P3, P5, P6, P10, P11, P12, P13, P14, P15,
P17, P18 e P20 apresentaram as menores fra??es granulom?tricas variando de areia muito fina
a areia m?dia. As demais esta??es de coleta variaram de areia fina a areia m?dia, exceto o
ponto P8 que apresentou somente granulometria do tipo areia m?dia e P19, indicando
granulometria do tipo grossa. A pequena correla??o da mat?ria org?nica com os elementos
estudados neste trabalho sugere que estes n?o sejam de origem antr?pica e sim de suporte
geoqu?mico

Previous issue date: 2010-09-06 / This study approaches the question of the administrative procedure of the environmental
licensing of ranks of fuel resale, taking as basis a study case of the reality of the City of
Natal/RN (Brazil). For in such a way, it was done a retrospect on the evolution of the
system of road transport in Brazil, having started to briefly analyze the urbanization
process that if after accented in the capitals of the Brazilian States the decade of 1950,
relating these subjects with the growth of the sector of fuel resale. After that, it was
transferred boarding of the defense of the national environment to the light of ambient
principles constitutional. In the sequence, a boarding on the ambient guardianship in the
Federal Constitution of 1988 was made, treating basically specifies and on the national
urban politics and the national politics of the environment, with its instruments. In the
sequence, it was transferred the analysis of the abilities and attributions of the National
Advice of the Environment (CONAMA) and its Resolutions, for then only enter in the
most important part of this work: an analysis of the environmental licensing of ranks of
fuel resale, in the reality of the City of Natal/RN. Before this specific boarding, it was
proceeded specifically a survey and communication from the applicable norms to such
establishments (Resolutions of the CONAMA and norms of the ABNT), for after that
carrying through an geo-ambient characterization of the City of Natal/RN. Finally, a
reflection was made on the possibility of magnifying of the state activity, in terms of
guarantees for the responsible members for the environmental policy and of
administrative efficiency, through the idea of the ambient regulation. For the
accomplishment of this study, it was proceeded research in diverse sources such as
books, magazines, sites of the Internet, periodicals, thesis and dissertations, among
others material, beyond visits the agencies that direct or indirectly act with the ambient
defense and as fuel resale, such as Secretariat of Environment and Urbanism of the City
of Natal (SEMURB), Institute of Economic Development and Environment of RN
(IDEMA), Brazilian Institute of the Environment and the Natural resources You renewed,
Executive Management of RN (IBAMA/RN), Public prosecutor's office of the
Environment of Natal (Public prosecution service of the RN), National Agency of Oil
(ANP) and Union of the Retailing of Derivatives of Oil of the RN, among others. To the
end, satiated regulation is observed that although on the substance of the ambient
licensing in ranks of fuel resale, also with federal, state and municipal norms, the
municipal Public Power is very far from the fulfilment of its institutional functions, in the
question environmental policy of these establishments, a time that few are the permitted
ranks of resale in the city of Natal/RN / Esta disserta??o aborda a quest?o do procedimento administrativo do licenciamento
ambiental de postos de revenda de combust?veis, tomando-se como base um estudo de
caso da realidade do Munic?pio de Natal/RN. Para tanto, partiu-se de um retrospecto
sobre a evolu??o do sistema de transporte rodovi?rio no Brasil, passando a analisar
brevemente o processo de urbaniza??o que se acentuou nas capitais dos Estados
brasileiros ap?s a d?cada de 1950, relacionando estes temas com o crescimento do
setor de revenda de combust?veis. Em seguida, passou-se a abordagem da defesa do
meio ambiente nacional ? luz de princ?pios constitucionais ambientais. Na seq??ncia, foi
feita uma abordagem sobre a tutela ambiental na Constitui??o Federal de 1988,
tratando especifica e basicamente sobre a pol?tica urbana nacional e a pol?tica nacional
do meio ambiente, com seus instrumentos. Na seq??ncia, passou-se ? an?lise das
compet?ncias e atribui??es do Conselho Nacional do Meio Ambiente (CONAMA) e de
suas Resolu??es, para s? ent?o adentrar na parte mais importante do trabalho: uma
an?lise do licenciamento ambiental de postos de revenda de combust?veis, na realidade
do Munic?pio de Natal/RN. Antes desta abordagem espec?fica, procedeu-se a um
levantamento e explana??o das normas aplic?veis especificamente a tais
estabelecimentos (Resolu??es do CONAMA e normas da ABNT), para em seguida
realizar uma caracteriza??o geo-ambiental do Munic?pio de Natal/RN. Por fim, realizouse
uma reflex?o sobre a possibilidade de amplia??o da atividade estatal, em termos de
garantias para os membros respons?veis pela fiscaliza??o ambiental e de efici?ncia
administrativa, atrav?s da id?ia da regula??o ambiental. Para a realiza??o deste estudo,
procedeu-se a pesquisas em diversas fontes tais como livros, revistas, s?tios da internet,
jornais, teses e disserta??es, entre outros materiais, al?m de visitas a ?rg?os que direta
ou indiretamente atuam com a defesa ambiental e como revenda de combust?veis, tais
como Secretaria de Meio Ambiente e Urbanismo do Munic?pio de Natal (SEMURB),
Instituto de Desenvolvimento Econ?mico e Meio Ambiente do RN (IDEMA), Instituto
Brasileiro do Meio Ambiente e dos Recursos Naturais Renov?veis, Ger?ncia Executiva
do RN (IBAMA/RN), Promotoria do Meio Ambiente de Natal (Minist?rio P?blico do RN),
Ag?ncia Nacional do Petr?leo (ANP) e Sindicato do Com?rcio Varejista de Derivados de
Petr?leo do RN, entre outros. Ao final, observa-se que apesar de farta regulamenta??o
sobre a mat?ria do licenciamento ambiental em postos de revenda de combust?veis,
inclusive com normas federais, estaduais e municipais, o Poder P?blico municipal est?
muito aqu?m do cumprimento de suas fun??es institucionais, no quesito fiscaliza??o
ambiental destes estabelecimentos, uma vez que poucos s?o os postos de revenda
licenciados na cidade de Natal/RN
