Federal Register API

Busca cada norma, propuesta, aviso y orden ejecutiva del Federal Register por palabra clave, agencia y fecha

El diario oficial del gobierno de EE.UU., consultable. Busca cada documento del Federal Register — reglas finales, propuestas, avisos y documentos presidenciales — por palabra clave, tipo, agencia y fecha (reglas finales de 'artificial intelligence': 318 y contando), con titulo, resumen, agencias, fecha de publicacion y enlaces HTML y PDF, mas detalle completo con referencias CFR, expedientes, fechas de vigencia, plazos de comentarios y URLs de texto crudo. Un endpoint dedicado de ordenes ejecutivas cubre cada EO desde la administracion Clinton con numero, fecha de firma y presidente — filtra por presidente (Obama: exactamente 294) o rango de fechas; nombres como 'obama' resuelven a los identificadores oficiales. Un directorio de agencias (con los slugs que esperan los filtros) lo completa. Las respuestas proxean la API oficial de los Archivos Nacionales con cache de 1 hora, y la peculiaridad del upstream que impone un minimo de 20 por pagina esta manejada para que las paginas nunca salten documentos. Legal tech, monitoreo de cumplimiento, investigacion de politicas, inteligencia de lobby y redacciones.

Cada llamada necesita la cabecera X-Api-Key. Una clave gratuita incluye 500 tokens al mes, sin tarjeta. 2 tokens por llamada, así que el plan gratuito cubre unas 250 llamadas al mes.

Colorado's 2022 regional haze SIP revision addresses the requirement that states revise their long-term strategies every implementation period to make reasonable progress towards the national goal of preventing any future, and remedying any existing, anthropogenic impairment of visibility, including regional haze, in mandatory Class I Federal areas (Class I areas). We are disapproving Colorado's 2022 regional haze SIP revision pursuant to the CAA and regulatory regional haze requirements. The EPA is not taking final action at this time on a separate revision to Colorado's SIP that consolidates existing, previously approved regional haze provisions into the same regulation where Colorado's new, second planning period provisions are located.",

      "subtype": null,
      "abstract": "The U.S. Environmental Protection Agency (EPA, or Agency) is finalizing amendments to the new source performance standards (NSPS) for stationary combustion turbines and stationary gas turbines pursuant to a review required by the Clean Air Act (CAA). As a result of this review, the EPA is establishing subcategories for new, modified, or reconstructed stationary combustion turbines based on size, rates of utilization, design efficiency, and fuel type. The EPA determined that combustion controls are the best system of emission reduction (BSER) for nitrogen oxide (NO<INF>X</INF>) emissions for most new, modified, or reconstructed stationary combustion turbines. For one subcategory, the BSER for NO<INF>X</INF> is combustion controls with the addition of selective catalytic reduction (SCR). The EPA further determined that the BSER for sulfur dioxide (SO<INF>2</INF>) emissions has not changed since the last NSPS review. Based on these determinations, the Agency is promulgating standards of performance in a new subpart of the Code of Federal Regulations (CFR). The Agency is also adding a subcategory for stationary combustion turbines that are used in temporary applications, exempting certain sources from title V requirements, and finalizing other provisions. The EPA is finalizing amendments to existing regulations to address or clarify specific technical and editorial issues.",
