Environmental Complaint Form Spain (Denuncia Medioambiental)

An Environmental Complaint Form Spain (Denuncia Medioambiental) is a formal written complaint submitted by a natural person, legal entity, or NGO to the competent environmental authority — the autonomous community's consejería de medio ambiente, the Ministerio para la Transición Ecológica y el Reto Demográfico (MITECO), the Confederación Hidrográfica (river basin authority) under the Ministerio de Transición Ecológica, the Agencia Estatal de Meteorología (AEMET), or the Guardia Civil's SEPRONA (Servicio de Protección de la Naturaleza) — alleging that a public or private actor has violated Spanish environmental law or European Union environmental law applicable in Spain. The environmental complaint is grounded in Ley 21/2013, de 9 de diciembre, de Evaluación Ambiental, which under Article 1 establishes the legal framework for environmental assessment of plans, programmes, and projects with significant environmental effects, and in Ley 26/2007, de 23 de octubre, de Responsabilidad Medioambiental, which transposes EU Directive 2004/35/CE on environmental liability and establishes the operator's obligation to prevent and remediate environmental damage.

Spain's environmental regulatory framework is extensive and multi-layered. At EU level, key instruments applicable in Spain include: EU Directive 2010/75/EU on industrial emissions (transposed through Real Decreto 815/2013); EU Directive 2011/92/EU on environmental impact assessment of projects (transposed through Ley 21/2013 and Real Decreto 2/2020); the Water Framework Directive 2000/60/EC (transposed through the Ley de Aguas — Real Decreto Legislativo 1/2001); the Habitats Directive 92/43/CEE and Birds Directive 2009/147/CE (transposed through Ley 42/2007 del Patrimonio Natural y de la Biodiversidad, as amended by Ley 33/2015); the Air Quality Directive 2008/50/EC (transposed through Real Decreto 102/2011); the Waste Framework Directive 2008/98/EC (transposed through Ley 7/2022 de Residuos y Suelos Contaminados para una Economía Circular); and EU Regulation 2018/842 on national emissions reductions. At national level, key legislation includes Ley 26/2007 de Responsabilidad Medioambiental, Ley 21/2013 de Evaluación Ambiental, Ley 33/2015 de Patrimonio Natural, and the Código Penal (LO 10/1995) Articles 325–331 which establish criminal environmental offences (delitos contra el medio ambiente).

Environmental complaints in Spain may be directed at: (1) private operators (empresas, autónomos, agricultural enterprises) for polluting activities, illegal waste disposal, illegal construction in protected natural areas, or operation without required environmental permits; (2) public administrations for failure to assess environmental impacts of infrastructure projects, failure to enforce environmental obligations on permit holders, or operation of public facilities in violation of environmental permits; and (3) individuals for specific activities such as burning waste, hunting protected species, or dumping waste in unauthorised locations.

The Guardia Civil's SEPRONA is the primary environmental law enforcement body in Spain for field investigations — operating under the Ministerio del Interior and coordinating with autonomous community environmental agencies, it investigates suspected environmental crimes under Articles 325–331 of the Código Penal and administrative infractions under autonomous community environmental legislation. SEPRONA patrols protected natural areas (Red Natura 2000 — established under Directive 92/43/CEE and 2009/147/CE), river courses, coastlines, and waste disposal sites throughout Spain. Environmental complaints involving criminal conduct should be submitted both to the competent administrative authority and as a denuncia penal (criminal complaint) before the Juzgado de Instrucción of the relevant jurisdiction or directly to SEPRONA.

An Environmental Complaint Form Spain is needed whenever a citizen, community association, or environmental organisation observes environmental damage, pollution, or a breach of environmental law and wishes to trigger an official administrative investigation or criminal enforcement action under the framework established by Ley 21/2013 de Evaluación Ambiental, Ley 26/2007 de Responsabilidad Medioambiental, or the Código Penal Articles 325–331.

The complaint is needed when illegal waste dumping (vertido ilegal de residuos) is observed — whether industrial waste in a river or ravine (barranco), agricultural waste in unauthorised locations, or construction debris (escombros) dumped in natural areas in violation of Ley 7/2022 de Residuos y Suelos Contaminados para una Economía Circular. The complaint should be directed to the autonomous community's consejería de medio ambiente and SEPRONA, specifying the GPS coordinates, cadastral reference (referencia catastral), and any photographs with date and location metadata. The Agencia Estatal de Administración Tributaria (AEAT) may also be involved where unreported business activity generated the waste stream.

An Environmental Complaint is needed when a factory, agricultural operation, or municipal wastewater treatment plant (EDAR — estación depuradora de aguas residuales) discharges pollutants into rivers, groundwater, or the sea in violation of the Water Framework Directive (Directiva Marco del Agua 2000/60/EC), transposed through Real Decreto Legislativo 1/2001 (Ley de Aguas), or in violation of their discharge authorisation (autorización de vertido) issued by the Confederación Hidrográfica. The Confederación Hidrográfica del Ebro, del Tajo, del Guadalquivir, del Júcar, del Segura, or of the relevant basin authority is the competent body for water-related complaints, and can order immediate inspections of discharge points and collection of water samples for laboratory analysis.

The complaint is needed when construction or development activities are carried out in a protected natural area — Red Natura 2000 site, Natural Park (Parque Natural), National Park (Parque Nacional), or area protected under Ley 42/2007 del Patrimonio Natural — without the required environmental impact assessment (EIA) under Ley 21/2013 or without authorisation from the competent authority. The autonomous community's consejería de medio ambiente and the Juzgado de lo Contencioso-Administrativo under Ley 29/1998 (LJCA) are the relevant forums for challenging unlawful construction permits issued without mandatory EIA.

An Environmental Complaint Form is needed when an industrial facility (instalación industrial) operates without the required Autorización Ambiental Integrada (AAI) under Real Decreto Legislativo 1/2016 (which codified Ley 16/2002 de Prevención y Control Integrados de la Contaminación — IPPC), or exceeds the emission limits (valores límite de emisión — VLE) set in its AAI, contributing to air, water, or soil pollution. Non-compliance with the AAI triggers administrative sanctions ranging from €10,000 to €2,000,000 under RDL 1/2016 and may also constitute a criminal offence under Article 325 of the Código Penal.

The complaint is needed when a species of wild fauna or flora protected under Ley 42/2007 del Patrimonio Natural y de la Biodiversidad or the Catálogo Español de Especies Amenazadas is being harmed — through illegal hunting (caza furtiva), trapping, collection, or destruction of habitat — triggering enforcement action by SEPRONA and potential criminal prosecution under Article 334 of the Código Penal. Protected species include wolves (Canis lupus), Iberian lynx (Lynx pardinus), lammergeier (Gypaetus barbatus), brown bear (Ursus arctos), and thousands of plant and invertebrate species listed in the Catálogo Español de Especies Amenazadas.

The complaint is also warranted when noise pollution (contaminación acústica) from industrial, commercial, or leisure activities exceeds the limits established by Ley 37/2003 del Ruido and its implementing Real Decreto 1513/2005, or when artificial light (contaminación lumínica) from poorly designed or unshielded installations damages protected natural areas contrary to Real Decreto 1890/2008. The Ayuntamiento handles urban noise complaints, while MITECO and the autonomous community handle noise in protected natural areas.

A complete Environmental Complaint Form Spain must contain the following key elements to allow the competent authority — the autonomous community's environmental agency, SEPRONA, or MITECO — to investigate effectively and take enforcement action under Ley 21/2013, Ley 26/2007, and the Código Penal.

Complainant Identification: Full name, DNI/NIE or company NIF, address, telephone, and email of the complainant. Under Article 62 of Ley 39/2015 (LPAC), anonymous complaints are admissible as a basis for initiating an administrative investigation (actuaciones previas), but identified complaints are given greater weight and the authority must formally respond to the complainant. For NGOs and citizen associations (asociaciones de defensa del medio ambiente), the entity's NIF, registered address, and the name of the legal representative must be provided. Environmental associations registered in the Registro Nacional de Asociaciones (Ministerio del Interior) and operating for at least two years have full legal standing under Ley 27/2006 (Aarhus Convention transposition) to file complaints and challenge administrative environmental decisions before the Juzgados de lo Contencioso-Administrativo.

Location and Identification of the Violation: The precise location of the environmental violation — municipality, province, GPS coordinates if available, cadastral reference (referencia catastral), river name and kilometre point, or natural area designation. The more precise the location data, the easier it is for SEPRONA or the environmental agency to inspect the site. Photographs, videos, or satellite imagery attached to the complaint significantly strengthen its evidential value and are admissible as documentary evidence in both administrative and criminal proceedings before Spanish courts.

Identification of the Alleged Violator: Name, address, and NIF/CIF of the individual or company allegedly responsible for the violation, if known. For industrial facilities, the Número de Identificación del Registro (NIR) or the AAI permit reference number as published in the Boletín Oficial del Estado (BOE) or the relevant Boletín Oficial de la Comunidad Autónoma (BOCA). If the violator is unknown, the complaint can still proceed as an anonymous environmental violation investigation, with SEPRONA or the environmental agency conducting field work to identify the source.

Description of the Environmental Violation: A factual, specific, and detailed account of the environmental violation — the type of pollution or damage (air, water, soil, biodiversity), the estimated quantity and nature of pollutants or waste, the duration and frequency of the violation, and any prior complaints or reports already made. Reference to the specific legal provision allegedly violated — for example, Article 92 of Ley de Aguas (RDL 1/2001) for water pollution, Article 45 of Ley 42/2007 for species protection, or Article 7 of Ley 26/2007 for failure to prevent environmental damage — strengthens the complaint and guides the investigating authority toward the correct legal framework.

Evidence and Documentation: All available evidence — photographs (with date and location metadata), water or soil samples, laboratory analysis results, witness statements, documents obtained from public registries (AAI permits, environmental impact declarations — DIA), or media reports. Under Ley 27/2006, de 18 de julio, por la que se regulan los derechos de acceso a la información, de participación pública y de acceso a la justicia en materia de medio ambiente (transposing the Aarhus Convention), the complainant has the right to access environmental information held by public authorities relevant to the complaint, including AAI permits, inspection reports, and sanction records.

Requested Action: A statement of the enforcement action or remedy being sought — administrative investigation and sanction, immediate inspection of the site, suspension of the polluting activity, remediation of environmental damage under Ley 26/2007, or criminal referral to the Fiscalía de Medio Ambiente (specialist environmental prosecutors attached to the Fiscalías Provinciales and the Fiscalía de Sala de Medio Ambiente y Urbanismo at the Fiscalía General del Estado). Where potential criminal environmental offences under Articles 325–331 of the Código Penal are involved, the complaint should also be submitted as a denuncia penal before the Juzgado de Instrucción for criminal investigation alongside the administrative route.

Forms-legal.com provides this Environmental Complaint Form Spain template as a practical tool for citizens, associations, and businesses reporting environmental violations. The Dirección General de Calidad y Evaluación Ambiental within MITECO (miteco.gob.es) and each autonomous community's environmental authority can advise on the correct filing procedure for specific violations. Complaints involving potential criminal environmental offences under Articles 325–331 of the Código Penal should be filed directly with the Juzgado de Instrucción as a denuncia penal or submitted to SEPRONA for criminal investigation.
